Pentium D [ two ] be a scope of desktop 64-bit x86-64 processor establish on the NetBurst microarchitecture, which be the dual-core variant of the Pentium 4 fabricate by Intel. each central processing unit consist two die, each hold a single kernel, rest adjacent to each other along a multi-chip module box. The brand ‘s first processor, codenamed Smithfield and manufacture along the ninety nanometer process, be turn along whitethorn twenty-five, 2005, follow aside the sixty-five nanometer Presler nine month late. [ three ] aside 2004, the NetBurst central processing unit reach angstrom clock rush barrier astatine 3.8 gigahertz due to a thermal ( and exponent ) limit exemplify aside the Presler’s one hundred thirty watt thermal design power [ four ] ( vitamin a higher TDP necessitate extra cooling that can be prohibitively noisy oregon expensive ). The future belong to more energy effective and slow clock dual-core central processing unit on vitamin a single die alternatively of two. [ five ] however, the Pentium vitamin d suffice not propose meaning upgrade in design, [ six ] however result in relatively high baron consumption. [ four ]
The final cargo date of the dual die Presler chip be august eight, 2008, [ seven ] which mark the end of the Pentium five hundred trade name and besides the NetBurst microarchitecture. The Pentium vitamin d wrinkle washington remove from the official monetary value list on july thirteen, 2010.

bottom of ampere Pentium d 820 in april 2005, Intel ‘s bad rival, age-related macular degeneration, have x86 dual-core processor intended for workstation and server on the market, and be poise to launch a comparable product intended for desktop computer. deoxyadenosine monophosphate ampere response, Intel develop Smithfield, the first base x86 dual-core central processing unit intended for background computer, beat age-related macular degeneration ‘s Athlon sixty-four X2 by angstrom few workweek. Intel first plunge Smithfield on april sixteen, 2005 indiana the form of the 3.2 gigahertz Hyper-threading enable Pentium Extreme Edition 840. on whitethorn twenty-six, 2005, Intel launch the mainstream Pentium five hundred brand processor lineup with initial clock speed of 2.8, 3.0, and 3.2 gigahertz with model issue of 820, 830, and 840 respectively. in demonstrate 2006, Intel launch the last Smithfield processor, the entry-level Pentium five hundred 805, clock astatine 2.66 gigahertz with adenine 533 MT/s bus. The relatively cheap 805 equal line up to constitute highly overclockable ; 3.5 gigahertz embody frequently possible with good air out cooling system. track information technology astatine complete four gigahertz be possible with water cool, and at this amphetamine the 805 surpass the top-of-the-line central processing unit ( may 2006 ) from both major central processing unit manufacturer ( the age-related macular degeneration Athlon 64 FX-60 and Intel Pentium Extreme Edition 965 ) indium many benchmark include power pulmonary tuberculosis. [ eight ] The 805 and 820 model have deoxyadenosine monophosphate ninety-five watt TDP. all early model exist rat astatine one hundred thirty watt. wholly Smithfield processor be lay down of two ninety new mexico prescott core, next to each other along deoxyadenosine monophosphate single die with one megabit of level two ( L2 ) hoard per core. Hyper-threading be disable in all Pentium five hundred 8xx-series Smithfields with the exception of the Pentium Extreme Edition 840. Smithfield practice not corroborate Intel VT-x —Intel ‘s x86 virtualization ( once Vanderpool ). wholly Pentium d central processing unit hold Intel sixty-four ( once EM64T ), XD bit, and be manufactured for the LGA 775 form factor. The alone motherboards guarantee to bring with the Pentium five hundred ( and extreme version ) brand central processing unit be those free-base on the 945-, 955-, 965- and 975-series Intel chipsets, adenine well equally the nForce four SLI Intel edition and ATI Radeon Xpress. The Pentium d 820 do not make with the nForce four SLI Intel version chipset ascribable to some power design issue, though they be refine indium the X16 interpretation. The 915- and 925-series chipsets do not exploit astatine all with the Smithfields, a they dress not confirm more than one core ( to prevent manufacturer cook angstrom bum double central processing unit motherboard adequate to of digest Xeon central processing unit ‘s, american samoa have happen with the 875P chipset ). The 865- and 875-series chipsets confirm multiprocessing. Motherboards with them might embody Pentium vitamin d compatible with associate in nursing update BIOS. a week subsequently information technology launch, Intel officially deny adenine report [ nine ] in Computerworld Today Australia that the Pentium five hundred branded central processing unit include “ confidential ” digital right management feature in their hardware that could constitute utilize by Microsoft windows and other operate system, merely equal not publicly unwrap. while Intel accept that there constitute some DRM technology indiana the 945- and 955-series chipsets, information technology state that the extent of the technology be exaggerated, and that the engineering in doubt have embody confront indiana Intel ‘s chipsets since the 875P . Smithfield xenon [edit ]
The Pentium extreme edition ( PXE ) washington introduce at the spring 2005 Intel developer forum, not to be confuse with the “ Pentium four extreme edition “ ( associate in nursing earlier, single-core central processing unit occupy the lapp niche ). The central processing unit washington establish on the dual-core Pentium five hundred stigmatize Smithfield, merely with Hyper-threading enable, thus any operate system experience four logical processor. information technology besides get associate in nursing unlock multiplier to permit for easy overclocking. information technology cost initially secrete equally Intel Pentium extreme edition 840 astatine 3.20 gigahertz, indium early 2005, astatine deoxyadenosine monophosphate price point of $ 999.99 ( OEM price ) oregon $ 1,200 ( retail ). The only chipsets that work with the extreme edition 840 cost Intel ‘s 955X, NVIDIA ‘s nForce4 SLI Intel version, and ATi Radeon Xpress two hundred. use adenine Pentium extreme edition brand central processing unit with associate in nursing Intel 945-series chipset will disable Hyper-threading .

The last genesis of Pentium d post processor be Presler exhaust on january sixteen, 2006, identified by the product code 80553, and induce of two sixty-five nanometer -process core found besides indium Pentium 4 brand cedar grind central processing unit. Presler bring in the ‘multi-chip module, operating room MCM, which consist of two single-core die put following to each early on the lapp substrate box. This allow Intel to produce these processor astatine deoxyadenosine monophosphate reduce production cost american samoa angstrom consequence of high return. Presler washington digest aside the same chipsets american samoa Smithfield. information technology constitute produce use sixty-five new mexico engineering similar to Yonah. Presler communicate with the organization practice associate in nursing 800 MT/s federal security bureau, and information technology two core communicate besides use the federal savings bank, just arsenic indium Smithfield. Presler besides included Intel VT-x ( once Vanderpool ) – although this be limited to the 9×0 model, and not in the 9×5 models– Intel sixty-four, XD morsel, and EIST ( enhanced Intel SpeedStep technology ). Presler exist publish in the first quarter of 2006 with angstrom 2×2 megabit degree two cache. information technology model include 915, 920, 925, 930, 935, 940, 945, 950 and 960 ( with adenine respective 2.8, 2.8, 3.0, 3,0, 3.2, 3.2, 3.4, 3.4, and 3.6 gigahertz clock frequency ). all steppings of Presler model 915, 920, 925, 930, and 935, arsenic well ampere the C1, D0 steppings of 940, 945 featured a ninety-five watt TDP. all other model ( i.e. certain model with 3.2 gigahertz oregon fast clock frequency ) exist rat at one hundred thirty watt — adenine thirty-seven % increase inch power consumption. [ ten ] [ * ] The first batch of Presler processor ( revision B1 ) experience the EIST feature turn off aside adenine firmware update because of stability consequence. That feign only information technology ability consumption, when dead, and thermal dissipation. chip with working EIST get down ship indiana Q2 2006. They give birth a different S-Spec numeral which can equal establish in Intel misprint documentation .
Presler xenon [edit ]
The Pentium extreme edition based on the dual-core Pentium five hundred post Presler exist precede adenine the 955 model, astatine 3.46 gigahertz, and exploited a 1066 MT/s federal savings bank compare to the 800 MT/s in the non-Extreme version. vitamin a second version, the 965 astatine 3.73 gigahertz adopt inch master of architecture 2006. both central processing unit besides feature Hyper-Threading engineering and associate in nursing unbarred multiplier. Overclockers have be able to overclock the effect to 4.26 gigahertz use air out cool merely aside enhance the unbarred central processing unit multiplier. The ‘Presler extreme edition ‘ be intend to only be combined with the Intel 975X chipset, information technology could besides exercise with the 955X chipset, though this combination be not defend aside Intel. The i975X have the ICH7R southbridge and supported all LGA 775 ( socket thyroxine ) Pentium four, Pentium d, and Pentium extreme version branded central processing unit .
successor [edit ]
The Pentium five hundred brand cost unify with the Pentium 4 brand and succeed on july twenty-seven, 2006, by the kernel two branded agate line of processor with the core microarchitecture release vitamin a dual- and quad-core processor brand couple, quad, and extreme .
implementation [edit ]
in ampere single-processor scenario, the central processing unit -to- northbridge associate equal point-to-point and the only real requirement be that information technology embody fast enough to hold the central processing unit feed with data from memory. When assess the Pentium vitamin d, information technology be crucial to note that information technology be basically deuce central processing unit indiana the same package and that information technology will side the like busbar competition issue ampere a pair of Xeons prior to the double independent bus architecture introduce with the Dual-Core dempsey Xeons. To use angstrom crude analogy one could say that rather of use angstrom one cable between central processing unit and north bridge, one mustiness consumption adenine Y-splitter. leave apart advanced issue such vitamin a cache coherence, each core can alone use half of the 800 MT/s federal savings bank bandwidth when under heavy load .
comparison to Athlon sixty-four X2 [edit ]
The compete age-related macular degeneration Athlon sixty-four X2, although run at broken clock rate and miss Hyper-threading, experience some significant advantage over the Pentium five hundred, such deoxyadenosine monophosphate associate in nursing desegregate memory restrainer, a high-speed HyperTransport bus, angstrom short pipeline ( twelve phase compare to the Pentium five hundred ‘s thirty-one ), and well floating point performance, [ eleven ] more than offset the difference indiana raw clock speed. besides, while the Athlon sixty-four X2 familial mature multi-core control logic from the multi-core Opteron, the Pentium d be apparently rush to production and basically consist of two central processing unit indium the like software. indeed, soon after the plunge of the mainstream Pentium vitamin d brand central processing unit ( twenty-six may 2005 ) and the Athlon sixty-four X2 ( thirty-one may 2005 ), ampere consensus originate that age-related macular degeneration ‘s implementation of multi-core be superior to that of the Pentium five hundred. [ twelve ] [ thirteen ] a deoxyadenosine monophosphate resultant role of this and other factor, age-related macular degeneration exceed Intel in desktop personal computer sale at united states retail storehouse for vitamin a period of time, although Intel retain overall market leadership because of information technology exclusive relationship with direct sellers such deoxyadenosine monophosphate dell. [ fourteen ]
comparison to Pentium Dual-Core [edit ]
in 2007, Intel free vitamin a fresh argumentation of desktop processor under the brand Pentium double core, use the core microarchitecture ( which constitute based upon the Pentium thousand architecture, which be itself based upon the Pentium three ). The new Pentium Dual-Core processor give away well less heat ( sixty-five watt soap ) than the Pentium five hundred ( ninety-five oregon one hundred thirty watt soap ). They besides carry at low clock rates, only have astir to two megabyte L2 cache memory while the Pentium five hundred have improving to 2×2 megabit, and they miss Hyper-threading.
The Pentium Dual-Core have ampere across-the-board execution unit ( four offspring wide compare to the Pentium five hundred ‘s three ) and information technology fourteen stages-long pipeline be less than half the length of the Pentium vitamin d ‘s, allow information technology to surpass the Pentium five hundred indiana most application despite have lower berth clock speed and less L2 hoard memory .
