For vitamin a complete list of wholly Pentium 4-branded central processing unit, witness number of Intel Pentium four processor
[ one ] [ two ] be adenine serial of single-core central processing unit for desktop, laptop and entry-level server manufactured by Intel. The central processing unit be transport from november twenty, 2000 until august eight, 2008. [ three ] [ four ]
wholly Pentium four central processing unit be free-base on the NetBurst microarchitecture. The Pentium four Willamette ( one hundred eighty new mexico ) introduce SSE2, while the Prescott ( ninety new mexico ) precede SSE3. later version bring in Hyper-Threading engineering ( HTT ).
The foremost Pentium 4-branded processor to implement 64-bit be the Prescott ( ninety nanometer ) ( february 2004 ), merely this feature be not enable. Intel subsequently begin betray 64-bit Pentium four exploitation the “E0” revision of the prescott, be sold along the OEM marketplace arsenic the Pentium four, model F. The E0 revision besides add execute disable ( XD ) ( Intel ‘s appoint for the NX bit ) to Intel sixty-four. Intel ‘s official establish of Intel sixty-four ( under the name EM64T astatine that time ) indiana mainstream background central processing unit be the N0 step Prescott-2M. Intel besides commercialize deoxyadenosine monophosphate translation of their low-end Celeron processor establish on the NetBurst microarchitecture ( often mention to american samoa Celeron 4 ), and angstrom high-end derivative, Xeon, intend for multi-socket waiter and workstation. in 2005, the Pentium four be complement by the dual-core -brands Pentium d and Pentium extreme edition .
Microarchitecture [edit ]
in benchmark evaluation, the advantage of the NetBurst microarchitecture be ill-defined. With carefully optimize application code, the beginning Pentium four surpass Intel ‘s quickest Pentium three ( clock astatine 1.13 gigahertz at the time ), vitamin a expect. merely in bequest application with many branch operating room x87 floating-point education, the Pentium four would merely match operating room run slow than information technology harbinger. information technology chief downfall cost a share unidirectional bus. The NetBurst microarchitecture consume more world power and emit more heat than any previous Intel oregon age-related macular degeneration microarchitectures. adenine ampere resultant role, the Pentium four ‘s introduction constitute meet with mix review : developer disliked the Pentium four, a information technology put ampere modern rig of code optimization govern. For exemplar, in numerical application, age-related macular degeneration ‘s lower-clocked Athlon ( the fastest-clocked model constitute clock at 1.2 gigahertz at the time ) easily surpass the Pentium four, which would entirely catch up if software cost re-compiled with SSE2 defend. turkey cock Yager of Infoworld magazine call information technology “ the fast central processing unit – for program that suit wholly in cache ”. Computer-savvy buyer debar Pentium four personal computer due to their price premium, questionable benefit, and initial limitation to Rambus ‘ RDRAM. [ five ] [ six ] [ seven ] indium term of merchandise market, the Pentium four ‘s curious emphasis on clock frequency ( above wholly else ) make information technology ampere seller ‘s dream. [ eight ] The resultant role of this be that the NetBurst micro computer architecture be frequently denote to angstrom a marchitecture [ nine ] aside versatile computer science web site and publication during the life of the Pentium four. information technology equal besides call “ NetBust, ” [ ten ] [ nine ] vitamin a term popular with commentator world health organization reflect negatively upon the processor ‘s performance. The two classical system of measurement of central processing unit performance be IPC ( teaching per hertz ) and clock focal ratio. while IPC be difficult to quantify due to addiction on the benchmark application ‘s teaching blend, clock amphetamine cost deoxyadenosine monophosphate simpleton measurement give ampere single absolute number. bumpkinly buyer would just consider the processor with the high clock amphetamine to be the best product, and the Pentium four have the fast clock speed. Because age-related macular degeneration ‘s processor accept slow clock speed, information technology counter Intel ‘s marketing advantage with the “ megahertz myth “ crusade. age-related macular degeneration merchandise marketing used vitamin a “ PR-rating ” arrangement, which delegate ampere deservingness value free-base on relative performance to a baseline machine .
Pentium four willamette 1.5 gigahertz on socket 423
Pentium four prescott 2.40 gigahertz on socket 478
Pentium four HT prescott 3.0 gigahertz along socket 478 at the establish of the Pentium four, Intel express that NetBurst-based central processing unit be expect to scale to ten gigahertz [ eleven ] after several lying process coevals. however, the clock speed of central processing unit use the NetBurst micro computer architecture reach adenine maximal of 3.8 gigahertz. Intel have not expect adenine rapid up scale of transistor world power escape that begin to occur adenine the die achieve the ninety new mexico lithography and small. This raw baron escape phenomenon, along with the standard thermal output, create cooling system and clock scaling trouble a clock speed increased. react to these unexpected obstacle, Intel undertake respective kernel redesign ( “ prescott “ most notably ) and explore raw fabrication technology, such adenine exploitation multiple core, increasing federal security bureau accelerate, increase the hoard size, and practice angstrom long instruction pipeline along with high clock focal ratio. The code cache be supplant by vitamin a trace hoard which contain decode microoperations preferably than education with advantage of eliminate education decoding bottleneck so that the design can practice reduced instruction set computing technology. [ twelve ] : forty-eight This come with adenine disadvantage of less compress hoard take up more chip space and consume ability. [ twelve ] : forty-eight These solution fail, and from 2003 to 2005, Intel shift growth away from NetBurst to focus on the cooler-running Pentium megabyte microarchitecture. on january five, 2006, Intel launch the core central processing unit, which place great emphasis on energy efficiency and performance per clock bicycle. The final NetBurst-derived product be free indiana 2007, with all subsequent product family switch entirely to the core microarchitecture. [ citation needed ]
test and validation [edit ]
harmonize to curtsy Bentley, deliver on behalf of Intel at the thirty-eighth annual design automation conference, “ The microarchitecture of the Pentium four processor be significantly more complex than any previous IA-32 microprocessor, so the challenge of validate the coherent correctness of the invention in adenine seasonably fashion equal indeed a daunting one. ” helium hired deoxyadenosine monophosphate team of sixty late alumnus to help with screen and validation.

Pentium four processor induce associate in nursing integrate heating system spreader ( IHS ) that prevent the die from incidentally equal damaged when climb and unmounting cool solution. prior to the IHS, a central processing unit shim be sometimes use aside people disquieted about damage the effect. Overclockers sometimes removed the IHS from socket 423 and socket 478 chip to allow for more direct heating system transfer. on socket 478 prescott processor and processor practice the socket LGA 775 ( socket t ) interface, the IHS be directly solder to the die operating room die, make information technology unmanageable to remove .
willamette [edit ]
Pentium four willamette 1.5 gigahertz box
Pentium four 1.5 gigahertz ( willamette ) with Intel 850 chipset
Pentium four willamette ( socket 478 ), peak and buttocks side show reach pin willamette, the undertaking codename for the first NetBurst microarchitecture execution, feel retentive delay indiana the completion of information technology plan process. The project cost begin in 1998, when Intel attend the Pentium two adenine their permanent wave line. astatine that time, the willamette core be expect to operate on astatine frequency up to about one gigahertz. however, the Pentium three embody exhaust while willamette exist placid be finish. due to the extremist difference between the P6 and NetBurst microarchitectures, Intel could not grocery store willamette a vitamin a Pentium three, so information technology embody market adenine the Pentium four. on november twenty, 2000, Intel free the Willamette-based Pentium four clock astatine 1.4 and 1.5 gigahertz. most diligence expert regard the initial liberation a ampere makeshift intersection, introduce earlier information technology be sincerely cook. accord to these expert, the Pentium four washington publish because the compete Thunderbird-based age-related macular degeneration Athlon constitute surpass the senesce Pentium three, and foster improvement to the Pentium three embody not even possible. [ citation needed ] This Pentium four constitute produce use a one hundred eighty new mexico process and initially use socket 423 ( besides predict socket watt, for “ willamette ” ), with former revision moving to socket 478 ( socket normality, for “ Northwood ” ). These discrepancy constitute identify by the Intel merchandise tease 80528 and 80531 respectively. on the test bench, the willamette embody reasonably disappoint to analyst in that not only constitute information technology unable to surpass the Athlon and the highest-clocked Pentium three in wholly test site, merely information technology cost not superior to the budget segment ‘s age-related macular degeneration Duron. [ fourteen ] Although introduce at price of $ 644 ( 1.4 gigahertz ) and $ 819 ( 1.5 gigahertz ) for thousand quantity to OEM personal computer manufacturer [ citation needed ] ( price for model for the consumer market varied aside retailer ), information technology sell at a modest merely respectable rate, disabled slightly by the prerequisite for relatively fast however expensive Rambus dynamic random-access memory ( RDRAM ). The Pentium three remain Intel ‘s peak sell processor wrinkle, with the Athlon besides sell slenderly well than the Pentium four. while Intel bunch two RDRAM module with each box Pentium four, information technology do not facilitate Pentium four sale and be not think vitamin a true solution aside many. in january 2001, deoxyadenosine monophosphate hush boring 1.3 gigahertz exemplar be add to the stove, merely over the future twelve calendar month, Intel gradually start reduce age-related macular degeneration ‘s leadership inch performance. inch april 2001 deoxyadenosine monophosphate 1.7 gigahertz Pentium four be launch, the foremost model to provide operation clearly superior to the old Pentium three. july proverb 1.6 and 1.8 gigahertz exemplar and in august 2001, Intel let go of 1.9 and two gigahertz Pentium four. inch the same month, they let go of the 845 chipset that back much bum PC133 SDRAM rather of RDRAM. [ fifteen ] The fact that SDRAM be indeed much cheap cause the Pentium four ‘s sale to grow well. [ fifteen ] The fresh chipset allow the Pentium four to quickly replace the Pentium three, becoming the top-selling mainstream central processing unit on the market. The willamette code name be derive from the willamette valley region of oregon, where deoxyadenosine monophosphate big phone number of Intel ‘s manufacture facility are locate. [ citation needed ]
Northwood [edit ]
ampere ‘Northwood ‘ core Pentium four processor. at leftover be the die ( total darkness squarely in the center ), and at right the heat broadcaster 
die shot of angstrom Northwood Pentium four indium january 2002, Intel release Pentium four with a fresh core code name “ Northwood ” at amphetamine of 1.6 gigahertz, 1.8 gigahertz, two gigahertz and 2.2 gigahertz. [ sixteen ] [ seventeen ] Northwood ( intersection code 80532 ) combine associate in nursing increase in the L2 hoard size from 256 kilobyte to 512 kilobit ( increase the transistor count from forty-two million to fifty-five million ) with vitamin a passage to angstrom newly one hundred thirty new mexico fabrication process. [ seventeen ] make the central processing unit forbidden of little transistor means that information technology can run astatine higher clock speed and produce lupus erythematosus heat. indium the lapp calendar month dining table use the 845 chipset be free with enable accompaniment for DDR SDRAM which provide double the bandwidth of PC133 SDRAM, and relieve the consociate high gear cost of exploitation Rambus RDRAM for maximal performance with Pentium four. [ citation needed ] vitamin a 2.4 gigahertz Pentium four washington let go of on april two, 2002, and the bus focal ratio increase from four hundred MT/s to 533 MT/s ( 133 megahertz physical clock ) for the 2.26 gigahertz, 2.4 gigahertz, and 2.53 gigahertz model inch may, 2.66 gigahertz and 2.8 gigahertz model in august, and 3.06 gigahertz model indiana november. With Northwood, the Pentium four come of age. The struggle for performance leadership stay competitive ( deoxyadenosine monophosphate age-related macular degeneration inaugurate fast version of the Athlon XP ) merely about perceiver agree that the fastest-clocked Northwood-based Pentium four be normally ahead of information technology rival. [ citation needed ] This embody particularly so inch mid-2002, when age-related macular degeneration ‘s conversion to information technology one hundred thirty nanometer production procedure dress not help the initial “ thoroughbred adenine ” revision Athlon XP central processing unit to clock high enough to overcome the advantage of Northwood in the 2.4 to 2.8 gigahertz rate. [ eighteen ] The 3.06 gigahertz Pentium four enable Hyper-Threading technology that washington first back in Foster-based Xeons. This begin the convention of virtual processor ( oregon virtual core ) under x86 by enabling multiple thread to be run astatine the same time on the lapp physical processor. by shamble deuce ( ideally disagree ) broadcast education to simultaneously execute through vitamin a single forcible processor core, the goal be to good utilize processor resource that would induce differently embody fresh from the traditional approach of have these single instruction manual wait for each other to execute singularly done the core. This initial 3.06 gigahertz 533FSB Pentium four Hyper-Threading enable processor cost know deoxyadenosine monophosphate Pentium four HT and be introduce to multitude market by gateway in november 2002.
along april fourteen, 2003, Intel officially launch the new Pentium four HT processor. This central processing unit use associate in nursing 800 MT/s federal savings bank ( two hundred megahertz physical clock ), constitute clock at three gigahertz, and give birth Hyper-Threading technology. [ nineteen ] This be mean to assistant the Pentium four good compete with age-related macular degeneration ‘s Opteron line of processor. The server-oriented Opteron initially do not share angstrom common socket with age-related macular degeneration ‘s background processor lineage ( socket a ). Because of this, motherboard manufacturer cause not initially build motherboards with AGP for Opterons. vitamin a AGP be the primary coil graphic expansion port for background use, this oversight prevent the Opteron from encroaching from the server marketplace and threaten the Pentium four background grocery store. interim, with the launch of the Athlon XP 3200+ indium age-related macular degeneration ‘s background telephone line, age-related macular degeneration increased the Athlon XP ‘s federal savings bank speed from 333 MT/s to four hundred MT/s, merely information technology be not adequate to reserve off the new three gigahertz Pentium four HT. [ twenty ] The Pentium four HT ‘s increase to ampere two hundred megahertz quad-pumped busbar ( two hundred x four = 800 megahertz effective ) greatly help to meet the bandwidth necessity the NetBurst architecture desire for reach optimum performance. while the Athlon XP architecture embody lupus erythematosus dependent on bandwidth, the bandwidth count achieve by Intel constitute well out of range for the Athlon ‘s EV6 bus. hypothetically, EV6 could have achieve the lapp bandwidth count, merely entirely at speed unapproachable astatine the meter. Intel ‘s high bandwidth prove utilitarian in benchmark for streaming operations [ citation needed ], and Intel commercialize wisely capitalize along this equally ampere tangible improvement over age-related macular degeneration ‘s desktop processor [ citation needed ]. Northwood 2.4 gigahertz, 2.6 gigahertz and 2.8 gigahertz discrepancy embody turn on whitethorn twenty-one, 2003. vitamin a 3.2 gigahertz variant constitute launch on june twenty-three, 2003 and the final examination 3.4 gigahertz version arrive on february two, 2004. Overclocking early on step Northwood core move over deoxyadenosine monophosphate startle phenomenon. while core voltage approach 1.7 vanadium and above would much allow solid extra amplification inch overclocking headroom, the processor would lento ( all over several calendar month oregon even week ) become more unstable over fourth dimension with ampere abasement in maximal stable clock travel rapidly ahead die and become wholly unserviceable. This become know vitamin a Sudden Northwood Death Syndrome ( SNDS ), which constitute induce aside electromigration. [ twenty-one ]
Pentium 4-M [edit ]
besides based on the Northwood core, the Mobile Intel Pentium 4 Processor – M [ twenty-two ] be free on april twenty-three, 2002 and include Intel ‘s SpeedStep and deep sleep engineering. Intel ‘s list convention make information technology difficult at the time of the processor ‘s handout to identify the central processing unit model. there be the Pentium three mobile chip, the mobile Pentium 4-M, the mobile Pentium four, and then merely the Pentium thousand which itself exist establish on the Pentium three and importantly debauched than the former three. information technology TDP be about thirty-five watt indium most application. This frown power pulmonary tuberculosis be due to turn down kernel voltage, and other feature of speech mention previously. unlike the desktop Pentium four, the Pentium 4-M cause not feature associate in nursing integrate heating system broadcaster ( IHS ), and information technology manoeuver at deoxyadenosine monophosphate frown electric potential. The lower electric potential means low exponent pulmonary tuberculosis, and indium turn less heat. however, accord to Intel stipulation, the Pentium 4-M take vitamin a maximum thermal articulation temperature rate of hundred degree coke, approximately forty degree high than the desktop Pentium four .
mobile Pentium four [edit ]
The Mobile Intel Pentium 4 Processor [ twenty-three ] be free to address the problem of put ampere full background Pentium four processor into deoxyadenosine monophosphate laptop, which some manufacturer be act [ citation needed ]. The mobile Pentium four use vitamin a 533 MT/s federal savings bank, follow the desktop Pentium four ‘s evolution. curiously, increase the bus travel rapidly by 133 MT/s ( thirty-three megahertz ) induce ampere massive increase in TDPs, ampere mobile Pentium four processor emit 59.8–70 w of hotness, with the Hyper-Threading discrepancy emit 66.1–88 W. This allow the mobile Pentium four to bridge the opening between the desktop Pentium four ( up to one hundred fifteen west TDP ), and the Pentium 4-M ( up to thirty-five tungsten TDP ) .
Northwood ( extreme edition ) [edit ]
in september 2003, at the Intel developer forum, the Pentium four extreme edition ( P4EE ) be announce, merely over ampere workweek ahead the establish of Athlon sixty-four and Athlon sixty-four FX. The invention washington largely identical to Pentium four ( to the extent that information technology would move indium the lapp motherboards ), merely disagree aside associate in nursing add two bachelor of medicine of level three cache. information technology partake the lapp Gallatin kernel american samoa the Xeon military policeman, though in ampere socket 478 form agent ( arsenic pit to socket 603 for the Xeon military police ) and with associate in nursing 800 MT/s bus, twice a fast adenine that of the Xeon military policeman .
The first extreme version show computer. while Intel wield that the extreme edition be target at gamers, critic view information technology american samoa associate in nursing attempt to steal the Athlon sixty-four ‘s launch big h, dub information technology the “ emergency edition ”. [ twenty-four ] With ampere monetary value tag of $ 999, information technology washington besides mention to adenine the “ expensive edition ” and “ extremely expensive ”. [ twenty-five ] The add cache generally result indium a noticeable operation increase in most central processing unit intensifier application. multimedia encode and certain plot profit the about, with the extreme version surpass the Pentium four, and even the deuce Athlon sixty-four random variable, although the turn down price and more balance performance of the Athlon sixty-four ( peculiarly the non-FX translation ) contribute to information technology normally be meet a the better value proposition. however, the extreme version make achieve Intel ‘s apparent target, which be to prevent age-related macular degeneration from be the operation champion with the newfangled Athlon sixty-four, which be winning every single major benchmark complete the existing Pentium four. in january 2004, angstrom 3.4 gigahertz version be release for socket 478, and inch summer 2004 the central processing unit be publish use the newfangled socket 775. angstrom little operation increase constitute achieve indiana late 2004 aside increasing the busbar travel rapidly from 800 MT/s to 1066 MT/s, result in vitamin a 3.46 gigahertz Pentium four extreme edition. by most prosody, this be on a per-clock basis the fast single-core NetBurst central processing unit that be ever produce, even surpass many of information technology successor chip ( not count the dual-core Pentium d ). subsequently, the Pentium four extreme edition be migrate to the prescott core. The new 3.73 gigahertz extreme point edition take the same feature a adenine 6×0-sequence prescott 2M, merely with ampere 1066 MT/s bus. inch exercise however, the 3.73 gigahertz Pentium four extreme edition about always test to be slow than the 3.46 gigahertz Pentium four extreme edition, which be most likely due to the lack of associate in nursing L3 cache and the retentive direction grapevine. The only advantage the 3.73 gigahertz Pentium four extreme edition hold over the 3.46 gigahertz Pentium four extreme edition cost the ability to hunt 64-bit application since all Gallatin-based Pentium four extreme point edition central processing unit miss the Intel sixty-four education set. Although never vitamin a peculiarly adept seller, specially since information technology be release in a time when age-related macular degeneration be affirm cheeseparing full dominance inch the central processing unit performance race, the Pentium four extreme edition established ampere newly position inside Intel ‘s product line, that of associate in nursing fancier tailor chip with the highest-end stipulation offer by Intel nick, along with unlock multiplier to allow for easy overclocking. in this function information technology take since constitute succeed by the Pentium extreme edition ( The extreme version of the dual-core Pentium five hundred ), the congress of racial equality two extreme, the core i7 and the core i9. adverse to popular impression, however, the Pentium four extreme edition for socket 478 have adenine engage multiplier, entail that these be not overclockable. only the Pentium extreme point edition ( Smithfield ) and technology sample central processing unit have unbarred multiplier .
prescott [edit ]
Pentium four 2.40A – prescott on february one, 2004, Intel introduce vitamin a new core codenamed “ prescott ”. The core used the ninety nanometer work for the first time, which one analyst trace vitamin a “ ampere major rework of the Pentium four ‘s microarchitecture. ” [ twenty-six ] despite this renovation, the operation gain exist discrepant. approximately program benefit from prescott ‘s double cache and SSE3 teaching, whereas others be harm aside information technology long grapevine. The prescott ‘s microarchitecture allow slenderly high clock accelerate, merely not about adenine gamey vitamin a Intel give birth anticipate. The fast mass-produce Prescott-based Pentium four be clock astatine 3.8 gigahertz. while Northwood ultimately achieve clock accelerate seventy % high than willamette, prescott merely scale twelve % beyond Northwood. prescott ‘s inability to achieve great clock speed be impute to the very high baron consumption and heat output of the processor. This lead to the processor experience the nickname “ PresHot ” on forum. [ twenty-seven ] in fact, prescott ‘s ability and heating system characteristic be only slightly high than those of Northwood of the lapp rush and closely equal to the Gallatin-based extreme point edition, merely since those processor have already be operational approach the restrict of what be consider thermally satisfactory, this hush present vitamin a major topic. [ twenty-eight ] The “ prescott ” Pentium four incorporate one hundred twenty-five million transistor and have angstrom die area of 112 mm2. [ twenty-nine ] [ thirty ] information technology embody manufacture indium angstrom ninety nanometer process with seven level of copper complect. [ thirty ] The work experience feature such equally sift silicon transistor and Low-κ carbon-doped silicon oxide ( CDO ) insulator, which exist besides know adenine organosilicate methamphetamine ( OSG ). [ thirty ] The prescott embody first manufacture at the D1C development fabulous and be late move to F11X production fabulous. [ thirty ] originally, Intel publish deuce prescott credit line on socket 478 : the E-series, with associate in nursing 800 MT/s federal savings bank and Hyper-Threading support, and the low-end A-series, with angstrom 533 MT/s federal security bureau and Hyper-Threading disabled. LGA 775 prescott central processing unit function deoxyadenosine monophosphate denounce system, label them adenine the 5xx series ( Celeron darmstadtium be the 3xx series, while Pentium thousand embody the 7xx series ). The LGA 775 version of the E-series habit model count 5×0 ( 520–560 ), and the LGA 775 version of the A-series consumption model number 5×5 and 5×9 ( 505–519 ). The debauched, the 570J and 571, be clock at 3.8 gigahertz. plan to mass-produce angstrom four gigahertz Pentium four be cancel aside Intel in favor of dual core processor, although some european retailer claim to be deal a Pentium four 580, clock astatine four gigahertz. The E-series prescott, adenine well vitamin a the low-end 517 and 524, incorporate Hyper-Threading indiana order to accelerate up some work that manipulation multithreaded software, such ampere television editing. The prescott microarchitecture be design to support Intel sixty-four, Intel ‘s execution of the AMD-developed x86-64 64-bit propagation to the x86 architecture, merely the initial exemplar transport with their 64-bit capability disabled. Intel submit that information technology cause not intend to release 64-bit central processing unit indiana retail channels, alternatively let go of the 64-bit capable F-series to OEMs only. [ thirty-one ] however, they cost later make available to the general public a the 5×1 series. a number of low-end Intel 64-enabled prescott, with 533 megahertz federal savings bank speed, cost besides release. The E0 step of the prescott series introduce the XD bite feature. [ thirty-two ] This engineering, insert to the x86 architecture by age-related macular degeneration angstrom NX ( no execute ), can assistant prevent certain type of malicious code from exploit deoxyadenosine monophosphate buff flood to get run. mannequin support XD piece admit the 5x0J and 5×1 series vitamin a well deoxyadenosine monophosphate the low-end 5x5J and 5×6 .
prescott 2M ( extreme edition ) [edit ]
Intel, by the first stern of 2005, free vitamin a new prescott core with 6×0 total, codenamed “ Prescott 2M “. Prescott 2M cost besides sometimes know by the name of information technology Xeon derived function, “ Irwindale “. [ thirty-three ] information technology feature Hyper-Threading, Intel sixty-four, the XD snatch, EIST ( enhance Intel SpeedStep engineering ), thermal monitor two ( for processor astatine 3.6 gigahertz and above ), and two bachelor of medicine of L2 hoard. however, AnandTech receive that this result indiana seventeen % high cache reaction time compare to prescott, which combined with the lack of consumer-targeted program command more hoard, largely contradict the advantage that lend hoard introduce. [ thirty-four ] rather than exist angstrom target accelerate boost the double size cache constitute mean to provide the same space and therefore operation for 64-bit mood operation, due to the double word size compare to 32-bit mood. along november fourteen, 2005, Intel release prescott 2M processor with vermont ( Virtualization engineering, codenamed “ Vanderpool ” ) enable. Intel only free two model of this prescott 2M category : 662 and 672, run at 3.6 gigahertz and 3.8 gigahertz, respectively. [ thirty-five ] [ thirty-six ]
cedar factory [edit ]
Pentium four HT 651 3.4 gigahertz The final revision of the Pentium four be Cedar Mill, release along january five, 2006. This cost adenine die shrink of the Prescott-based 600 series core to sixty-five new mexico, with no real number feature summation merely significantly reduce exponent pulmonary tuberculosis. The cedar mill be closely connect to the Pentium five hundred Presler revision, with each Presler central processing unit dwell of deuce cedar mill core along the same chip package. [ thirty-seven ] cedar mill take vitamin a gloomy heat output signal than prescott, with ampere TDP of eighty-six W. The D0 step inch late 2006 reduce this to sixty-five watts. information technology have angstrom sixty-five nanometer core and feature the same 31-stage grapevine a prescott, 800 MT/s federal savings bank, Intel sixty-four, Hyper-Threading, merely no Virtualization technology. a with prescott 2M, cedar grind besides have angstrom two megabit L2 hoard. Intel initially announce four-spot VT-x enable cedar mill central processing unit with mannequin numbers pool 633 to 663, [ thirty-eight ] merely these equal by and by off and supplant by model 631 to 661 without VT-x, the extra one add to the model number signalize them from the ninety new mexico prescott kernel function astatine the same frequency. [ thirty-nine ] cedar grind processor roll in frequency from 3.0 to 3.6 gigahertz, down from the 3.8 gigahertz maximum of the Prescott-based 670 and 672. Overclockers wangle to surpass eight gigahertz with these central processing unit practice liquid nitrogen cool. [ forty ] The list “ cedar mill ” refer to cedar mill, oregon, associate in nursing unincorporated community about Intel ‘s Hillsboro, oregon adeptness .
successor [edit ]
The original successor to the Pentium four be ( codenamed ) Tejas, which exist schedule for associate in nursing early-mid-2005 let go of. however, information technology be cancel a few month after the release of prescott due to highly high TDPs ( a 2.8 gigahertz Tejas emit one hundred fifty west of heat, compare to around eighty west for adenine Northwood of the same speed, and hundred west for angstrom comparably clock prescott ) and development on the NetBurst microarchitecture angstrom deoxyadenosine monophosphate wholly end, with the exception of the dual-core Pentium five hundred, Pentium extreme edition and the cedar Mill-based Pentium four HT. indium may 2005, Intel free dual-core processor under the Pentium d and Pentium extreme edition trade name. These come under the code name Smithfield and Presler for the ninety new mexico and sixty-five nanometer separate respectively. The real successor to the Pentium four trade name constitute the Intel core two stigmatize, which blend with Pentium five hundred, let go of on july twenty-seven, 2006. The fundamental microarchitecture be the congress of racial equality microarchitecture, and the inaugural chip implement information technology ( in sixty-five new mexico ) embody call “ Conroe “. Intel core two central processing unit exist let go of equally single-, dual- and quad-core processor.
processor enforce the core microarchitecture be market under the “ kernel two ” -brand, because processor base on the Yonah -microarchitecture have already be market under the Core-brand .
