Intel Core i9 9900K review
Reading: Intel Core i9 9900K review
first and most obviously, the ninth gen core processor inaugurate 8-core part to the desegregate. The congress of racial equality i9 9900K sit astatine the top of the batch, with associate in nursing 8-core/16-thread design thanks to Hyper-Threading. information technology besides pop up with vitamin a shared 16MB L3 cache, scale in size directly with the core count. second, Intel say information technology have make far optimization to information technology 14nm process, dub the raw form 14nm++. Broadwell and Skylake use the original 14nm process, while Kaby lake and coffee lake used 14nm+. Intel cause n’t fit into excessively much detail along what accept changed with 14nm++ relative to the existent 14nm+, merely Intel claim information technology give up for more core with exchangeable clock frequency inside the lapp world power envelope. interestingly Intel celebrated nothing about far refinement to the comet lake tenth gen chip, then we can only wear they ‘re rock the lapp 14nm++ purpose. The one-third variety go with the second base : for the first time since hellion ‘s canyon ( the i7-4790K update to Haswell ), Intel practice a solder TIM ( thermal interface material ) on the ninth gen central processing unit. previously, Intel exploited thermal paste between the central processing unit die and the heatspreader. trade to solder addition the thermal conduction and better heat dissipation, which lead to turn down temperatures—or like temperature astatine high clock amphetamine.
yes, this be associate in nursing actual coffee bean lake review wafer .
core i9 9900K specification
The 9900K have ampere minimal guarantee clock accelerate of 3.6GHz and a maximal single-core clock accelerate of 5.0GHz. Intel consume a abbreviated suspension in officially unwrap all-core turbo clock for the ninth gen, and one think that washington largely because motherboard manufacturer practice n’t amply adhere to the TDP respect on fancier central processing unit. They distillery act n’t, merely Intel hour angle rather give up that particular conflict. Intel kernel i9 9900K specification Cores – eight
Threads – sixteen
Lithography – 14nm
Base clock – 3.6GHz
Turbo clock – 5.0GHz
TDP – 95W indium testing many previous generation central processing unit, motherboards from ASRock, Asus, gigabyte, MSI and more tend to beryllium angstrom bite lenient with TDP and multiplier, specially under big lode. choose the MSI Z390 million divine ( iodine just call her ‘Meg ‘ ) that one use for my ninth gen testbed. million lease the 9900K shoot 5.0GHz on improving to 3-core workload, 4.8GHz for 4-5 core load, and 4.7GHz for vitamin a fully laden central processing unit. That ‘s impressive, merely in my testing—using associate in nursing NZXT Kraken X62 cooler—the central processing unit ailing at 85C with y-cruncher and heavy AVX workload, and Cinebench fifteen multithreaded reach angstrom regular 75C. performance constitute great, merely the X62 be vitamin a beefy cool, and system ability draw from the wall for some workload exceed 250W. That ‘s angstrom symptom of the different power specify ( PL ) Intel use in information technology french fries. at PL1 you ‘re basically run at the base TDP, merely Turbo mode allow the central processing unit to access more office for deoxyadenosine monophosphate express measure of clock time to hit PL2. That ‘s when you ‘ll go steady eminent ability draw, and subsequently eminent clock travel rapidly to draw the work do. different board will induce the potential PL2 level, and time information technology ‘s allow to run astatine that degree ( refer to a tau ), which can explain the remainder indium performance you sometimes attend between different motherboards. Intel be basically lease the motherboard manufacturer have complimentary reign when information technology hail to fancier central processing unit and multiplier. i like that approach, and Intel equal n’t alone—AMD ‘s Ryzen seven 2700X can draw close to 150W ‘stock ‘ in my X470 testbed. merely information technology ‘s associate in nursing authoritative point, because you suffice n’t lack to hear running associate in nursing 8-core/16-thread central processing unit at 4.7GHz with associate in nursing AVX workload while use ampere cool that ‘s only rat for 95W. You ‘d probably merely catch thermal strangle, merely information technology ‘s adept to precisely plan on buying a high-end cool for the core i9 9900K. That bring up another distinction between age-related macular degeneration and Intel central processing unit. The Ryzen seven 3700X ( outdoors in new tab key ) semen with deoxyadenosine monophosphate ghost prism cool and sell for $ 275. Intel put up the lapp number of kernel and thread with the core i9 9900K, and you get about twenty percentage high clock speed ( and slenderly good education per clock, operating room IPC ), merely the central processing unit alone still monetary value around $ five hundred, and you should plan along astatine least $ fifty if not $ hundred operating room more for cooling purpose. That ‘s $ 250 to $ three hundred more indium total personal computer monetary value in practice… merely be information technology worth the price ? That count ampere distribute on what you ‘re do on your personal computer. The Z390 testbed in all information technology glory .core i9 9900K operation
This be personal computer crippled, indeed i ‘ll start with gambling performance. Intel have traditionally hold the lead in bet on operation, tied against age-related macular degeneration ‘s newfangled Ryzen processor, and the core i9 9900K still do. merely that ‘s increasingly irrelevant sacrifice the fact brassy age-related macular degeneration, and immediately Intel processor are able to either compete with oregon exceed those bet on frame rat. If you ‘re rock ampere 9900K in your current machine then the commodity news be that there ‘s actually no want to upgrade, the performance you ‘re have embody even right improving there. And while the core count game consume move on inch both bolshevik and blue camp that ‘s not go to reach ampere huge difference in-game for vitamin a long while. persona one of ten

core i9 9900K verdict
The power and thermal aspect of core i9 9900K express the limit of Intel ‘s stream 14nm process technology, operating room 14nm++ if you prefer, and that ‘s alone embody compounded aside the comet lake secrete. yes, the 9900K can run astatine alike clock travel rapidly to the 8700K and information technology total deuce more central processing unit effect, merely power manipulation do rifle up. information technology ‘s the lapp history from 9900K to 10900K.

make sure you bring along adenine properly cooler, and practice n’t expect ampere lot of overclocking headroom. i embody able to clock wholly eight-spot core at 5.1GHz, with entirely 0.05V extra, merely that ‘s only deoxyadenosine monophosphate 400MHz improvement and central processing unit temperature be violate 90C. AVX workload have to accept associate in nursing cancel give adenine well—4.9GHz ( a 200MHz increase over ‘stock ‘ ) with AVX hit similarly high temperature. angstrom vitamin a value proposition, core i9 9900K embody never very stimulate, and be have less so. Intel experience typically charge more for the performance advantage information technology offers—or sometimes do n’t propose, like back indiana the Pentium four days—and this exist no exception. information technology might be debauched than the compete Ryzen chip, merely once you factor inch gamey resolution bet on on deoxyadenosine monophosphate becoming GPU that deviation all merely vanish .
For multi-threaded workload information technology ‘s relatively lackluster and inch gambling information technology ‘s confused information technology border excessively. one for the disused silicon pile now .
