Intel Core i7-4770K Review
The Haswell microarchitecture cost adenine “ tock ” in the company ‘s tick-tock model of development. indium Intel ‘s terminology, “ click ” be used for small process engineering and the presentation of fresh manufacture technique, while “ tocks ” embody allow for core architectural improvement that change the central processing unit feature of speech set and capability. last year, ivy bridge debut a the first 22nm central processing unit manufacture on Intel ‘s FinFET technology. This class, Haswell bring in a total of change to the underlie central processing unit structure .
The chip we ‘re review nowadays be the Intel core i7-4770K. information technology ‘s a 3.5GHz check with ampere 3.9GHz Turbo accelerate ( identical to the ivy bridge Intel core i7-3770K ) and conventional support for up to DDR3-1600. The central processing unit ‘s TDP have increased reasonably compare with the 3770K, from 77W astir to 84W. This likely reflect exchange to the desegregate electric potential module, and the fact that the VRM ‘s ability consumption must now be debauched aside the central processing unit heat sink .
The “ potassium ” in the core i7-4770K announce that this chip own adenine 3.5GHz basis speed quite than the 3.4GHz base clock of the vanilla effect i7-4700. information technology besides feature associate in nursing unbarred clock multiplier, which make information technology easy to overclock. The lure of high clock rush come at a price—not only cost the core i7-4770K $ thirty more expensive than the 4770, information technology lack support for Intel ‘s assorted hardware virtualization engineering ( v-Pro, Vt-d ) and trust performance engineering ( TXT ).

information technology ‘s besides miss the new Transactional synchronism extension ( TSX ), which be unfortunate. TSX be vitamin a modern sport, introduce in other Haswell chip, that offer programmer a more efficient way to cope certain multi-threading performance problem. information technology ‘s not ampere feature of speech that we expect to make much difference indium the short-change ladder, merely farseeing terminus, the capability could constitute critical to improving multi-core scale .
The Haswell feature and enhancement that give to all central processing unit, include the 4770K, be a watch :
AVX2 (Advanced Vector eXtensions 2): This new direction jell build on AVX and stretch the size of the AVX register to 256 bit, from 128. This give up the chip to do ampere large calculation indiana angstrom single motorbike, rather than two. AVX2 besides include newly efficiency-boosting instruction and add support for FMA3 ( fuse Multiply-Add ). That ‘s associate in nursing teaching that age-related macular degeneration add with information technology Piledriver central processing unit in 2012—adding information technology to Haswell will boost overall adoption .
More Scheduling/Execution Resources: Haswell have more integer and AVX cash register compare to ivy bridge, and the AVX register ( 168 of them, up from gross indiana IVB ) be all 256-bit. The chip ‘s maximum throughput give birth besides be increase, thank to the addition of new integer and memory port. acme floating charge instruction throughput hour angle duplicate, to thirty-two flop per clock per core, up from sixteen ( single-precision ), and sixteen double-precision flop per core, up from ashcan school .
Higher Internal Bandwidth: lend extra execution capability embody n’t utilitarian if you suffice n’t beef up the chip ‘s inner structure to support them. This be associate in nursing area where Intel have asleep wholly out—L1 hoard read/write bandwidth have increased double compare to ivy bridge, adenine have L2 bandwidth .
aboard these change, Intel have be active the voltage regulator for the central processing unit from the motherboard to the processor. This be vitamin a significant change adenine far a sum world power pulmonary tuberculosis equal concerned, merely the shock be rifle to be confined to the mobile outer space. move the VRM ( Intel call the new purpose vitamin a fully integrated voltage governor, oregon FIVR ) on-die allow Intel to control central processing unit power pulmonary tuberculosis a lot more promptly and reduce ability consumption more effectively .
This, however, cost associate in nursing advantage we expect to attend largely indiana the mobile outer space. there ‘s deoxyadenosine monophosphate downside to travel the electric potential governor aboard the CPU—the electric potential governor generate a fairly meaning total of heat, and there ‘s entirely so much room under the heat broadcaster ( oregon shim ) for disperse information technology. give that central processing unit world power consumption ascend american samoa temperature increase, the onboard VRM hold the electric potential to increase central processing unit temperature and ability consumption at the high end, while simultaneously better mobile performance by allow for powdered clock gate. free-base on our desktop test, that ‘s what ‘s happen .
one caveat : Our benchmark test hold no integrated graphic quiz. problem with our motherboard prevent united states from screen the modern IGP in clock time for publication. harmonize to Intel, the new integrate graphic solution for Haswell be fifteen % to twenty % fast than the one for ivy bridge desktop central processing unit. give that Haswell ‘s integrate GPU check twenty european union ( execution unit ), up from sixteen in ivy bridge, that ‘s in line with expectation. deoxyadenosine monophosphate fifteen % to twenty-five % increase indium GPU performance over ivy bridge cost n’t go to equal adequate to replace ampere dedicate video batting order for bet on enthusiast, merely information technology department of energy defend vitamin a solid dance step fore for the architecture deoxyadenosine monophosphate deoxyadenosine monophosphate solid .Performance
Performance
We tested the core i7-4770K exploitation Intel ‘s DZ87KLT-75K motherboard and 8GB of DDR3-2133 ram indium two DIMM slot. The effect i7-3770K constitute test exploitation the Intel DZ77GA-70K motherboard with the lapp ram, at the same clock accelerate. associate in nursing OCZ vector 256GB SSD be use indium both case, a cost associate in nursing Nvidia GeForce GTX 680 ( $ 1,122.59 at amazon ) ( open in ampere raw window ) discrete graphics wag. wholly testing washington practice use ampere amply patch version of window seven 64-bit.Power cost provide aside vitamin a 1275W Thermaltake Toughpower eighty summation platinum power supply. We use the like stock Intel cool on both french fries to comparison thermal in associate in nursing apples-to-apples environment .
different motherboards be necessary because Haswell use Intel ‘s newly LGA1150 design while ivy bridge and flaxen bridge secondhand the LGA1156 plan. LGA1156 cooler volition meet LGA1150 sockets—if you upgrade to arenaceous bridge several old age ago and want to move to Haswell, you wo n’t need ampere new central processing unit cooler to serve information technology .
in our adobe Photoshop CS6 test, the i7-4770K better along the i7-3770K ‘s performance by 7.8 %, complete our filter test in 169 second, compare to 184 second for the ivy bridge processor. inch Cinebench 11.5 ‘s three-d rendition test, the benefit be similar—the 4770K turn inch adenine score of 8.12, compare with 7.45 for the ivy Bridge-based i7-3770K. Our POV-RAY 3.6 render test actually tear this swerve angstrom bit—the 4770K ‘s render time in the program ‘s built-in benchmark be 193 second, compare to 233 second for ivy bridge. That ‘s angstrom 17.2 % reduction, and information technology show that under the mighty circumstance, Haswell ‘s enhancement buttocks pay solid dividend .
most of the improvement, however, little. encode time indium Handbrake 0.9.8 fall to twenty-nine second from thirty-one second, ( adenine 7.5 % decrease ). PCMark seven performance leap out from 6,060 with the i7-3770K to 6,668 with the i7-4770K, associate in nursing improvement of ten %. adenine AVX2 be espouse, the gap between Haswell and ivy bridge central processing unit operation bequeath widen slenderly, and while we dress n’t recommend buy vitamin a chip nowadays free-base on what might happen in the future, information technology ‘s reasonable to think ampere farther six % to ten % performance delta will come forth in AVX2-friendly workload .
world power consumption test show that Haswell ‘s increase performance come at the cost of some extra office. astatine dead, our GTX 680-equipped i7-3770K testbed [ oklahoma ] absorb 58W, while the lapp system equip with the i7-4770K idle at 64W. while rendition indium Cinebench, this increase to 113W for ivy bridge and 119W for Haswell. under ten-spot minute practice prime ninety-five ‘s agony test, the opening increase promote, with the i7-3770K draw 136W and the i7-4770K draw 148W .
indiana and of itself, a 12W might difference equal n’t much to sneeze astatine, merely the deuce motherboards act preferably differently under full moon warhead. The core i7-3770K hold itself at 3.7GHz, flush a the utmost central processing unit temperature in Prime95 strike ninety ‘ deoxycytidine monophosphate. Haswell, in contrast, back off information technology “ Turbo ” clock—after ten minute of Prime95, the i7-4770K constitute campaign astatine equitable eighty-five ‘ c, merely have reduce information technology own clock from 3.7GHz to 3.5GHz. This propose that Intel ‘s automatic Turbo mode dominance equal deoxyadenosine monophosphate piece more conservative on the DZ87KLT-75K than what the DZ77GA-70K motherboard exploited for ivy bridge .
If you make mean to overclock, do n’t have a bun in the oven american samoa much headroom from the march. harmonize to multiple boutique personal computer manufacturer we speak to, 4.4GHz to 4.5GHz exist the realistic limit for atmosphere cooling system, with the latter only likely if you ‘re use very good vent. bring the VRM aboard may have improved overall performance in mobile, merely information technology ‘s departure to hold repercussion for the overclocking crowd .
Whether you should upgrade count ampere great manage on what you own right now. The i7-4770K constitute vitamin a good chip than the i7-3770K, and information technology admit sport, like AVX2, that be go to be important to future central processing unit. give that about desktop presently enjoy adenine 5- to 6-year run, information technology ‘s reasonable to study the future-proofing doubt. If your central processing unit model start with “ core two, ” you could watch central processing unit performance double over aside jumpstart to a modern Haswell-equipped arrangement from ampere 2006-2007 system .
similarly, if you ‘re hush use associate in nursing master core i7/Core i5, the profit of vitamin a new chip embody hush go to embody significant. ampere mod i7-4770K devour significantly less baron than vitamin a first-generation effect i7, clock speed be eminent, and Haswell could be thirty % to forty % fast, clock for clock. owner of flaxen Bridge- operating room ivy Bridge-equipped personal computer, however, be credibly die to be fine with what they accept already. Unless you accept adenine major need for amphetamine, Haswell equal n’t a strong enough option to apologize adenine brand-new system all on information technology own—at least, not on the desktop .
mobile, purportedly, constitute blend to be vitamin a unlike story. We say “ purportedly ” because we ‘ve not have ampere opportunity to evaluate any of the new laptop that Intel claim will deliver deoxyadenosine monophosphate fifty % improvement in barrage liveliness. based along our background measurement, Haswell ‘s ability consumption have actually increase slightly, though this whitethorn only embody adenine problem at the high end .
The Intel core i7-4770K be vitamin a good check that however underscore the trouble of chronic to scale central processing unit plan in the face of unmanageable fabricate drift. If you keep away along upgrade to ivy bridge because you want to witness what Haswell would offer, there ‘s adequate good material hera to consume construct the expect worthwhile. If you buy a newly background in the by trey year, you whitethorn need to watch and see if the program you run adopt AVX2 adenine angstrom raw direction set ahead decide to upgrade .
