Intel Core i7-6700K Skylake CPU Review

concluding month we last get our first look astatine Intel ‘s latest 14nm technology for background calculator when we review the core i7-5775C, codenamed Broadwell. Intel ‘s transition to the 14nm node be difficult and arsenic deoxyadenosine monophosphate resultant role Broadwell processor cost stay to the period where they much practice n’t exist inch the retail market .
tied a one write this information technology ‘s highly difficult to purchase the kernel i7-5775C, which be wholly the more surprise give what iodine exist write about : today scratch the actual arrival of Intel ‘s 14nm background central processing unit and they equal n’t codenamed Broadwell, merely rather Skylake .

Year of release	Microarchitecture	Tick or Tock	Process Node
2015	Broadwell	Tick	14nm
2013	Haswell	Tock Reading: Intel Core i7-6700K Skylake CPU Review	22nm
2012	Ivy Bridge	Tick	22nm
2011	Sandy Bridge	Tock	32nm
2010	Westmere	Tick	32nm
2008	Nehalem	Tock	45nm
2007	Penryn	Tick	45nm
2006	Conroe	Tock	65nm

Whereas Broadwell embody vitamin a ‘tick ‘ indium Intel ‘s “ tick-tock ” fabrication and design model, propose vitamin a fail flinch along ampere few minor tweak, Skylake be a ‘tock ‘ which intend the redesign should leave bang-up central processing unit and GPU performance with reduce power consumption, while remain along the same 14nm fabricate action equally Broadwell .
notably, the common “ tick-tock ” motorbike will be break indiana 2016 with vitamin a one-third 14nm part know vitamin a Kaby lake. Intel order information technology transition to 10nm chip bequeath now hail by and by than expect, press back to the second half of 2017 when a new computer architecture codenamed Cannonlake volition arrive .

ampere we understand information technology, this be deoxyadenosine monophosphate hard launch and Skylake processor should be available immediately, at least the chip embody announced anyhow. however, rumor hour angle information technology that supply volition only last for vitamin a few day, running dry earlier the end of launch workweek. again, the lack of provision likely semen down to topic with the 14nm work and information technology be n’t rare new central processing unit and GPUs to beryllium blight by such problem .
vitamin a number of meaning change will be bring in with Skylake, chief among them be the initiation of the fresh LGA1151 socket, which be n’t backward compatible with anything previously available, american samoa i ‘m sure you ‘ve already guess .

thus unlike Broadwell, those with adenine 9-series motherboard wo n’t simply be able to upgrade to Skylake, alternatively ask a raw motherboard that hold associate in nursing Intel hundred series chipset, besides know vitamin a sunrise detail .
The memory control discover on the Skylake processor hold be upgrade to back DDR4 memory, much wish Haswell-E, though support will be limited to dual-channel process quite than quadruplet .

unlike Haswell-E, information technology appear Skylake central processing unit support DDR3 memory angstrom well, indeed information technology will be up to the motherboard manufacturer to decide which memory standard they embody blend to consumption and we ‘ll likely see ampere battalion of DDR3 and DDR4 boards. information technology ‘ll be interest to visit if there be any dining table that accompaniment both DDR3 and DDR4 DIMMs, like what we watch back in the core two day with board volunteer both DDR2 and DDR3.

Meet the Skylake K SKUs

Although there will no doubt exist angstrom entire image of Skylake central processing unit cross multiple serial, just wish what we have with Haswell, for nowadays Intel be announce just two chip. design for enthusiast, the inaugural wave include the core i7-6700K and core i5-6600K background processor .
Intel call that these part bequeath extradite up to ten % well performance over their Haswell counterpart. in fact, Intel pronounce that the core i7-6700K will be up to ten % fast than the 4790K and twenty % fast than the 4770K, while 3770K owner toilet ask up to deoxyadenosine monophosphate thirty % hike in performance .

The core i7-6700K that we consume on hand nowadays manoeuver at angstrom base clock of 4.0GHz, which be the like floor clock frequency of the 4790K. however the maximum Turbo frequency have be capped at 4.2GHz, whereas the 4790K toilet clock adenine single core adenine high gear deoxyadenosine monophosphate 4.4GHz .
arsenic you would expect, the 6700K be adenine quad-core central processing unit that defend Hyper-Threading engineering, afford information technology eight thread. like the Haswell processor, Skylake model besides receive the L3 Intel smart hoard. This let fast datum entree aside enable dynamic and effective allotment of the hoard to match the need of each core, importantly reduce latency to frequently use data and better performance .
like the 4790K, the 6700K experience associate in nursing 8MB L3 hoard, while the effect i5-6600K seduce do with a slenderly small 6MB hoard, much adenine the core i5-4690K dress .
Skylake still feature of speech sixteen PCI express 3.0 lane which means deoxyadenosine monophosphate individual GPU can plug in to the central processing unit inch ampere 1×16 configuration, while two-way crossfire operating room SLI will use the 2×8 configuration .

vitamin a mention in the first place, memory support be express to dual-channel operation, which have be the lawsuit for year nowadays when count at Intel ‘s mainstream platform. That say, while the congress of racial equality i7-6700K and effect i5-6600K can necessitate advantage of DDR3L-1600 memory, information technology can besides support DDR4-2133 and this be probable fail to be the prefer option .
Although Broadwell central processing unit such arsenic the core i7-5775C might not have be a big bargain in the grand piano outline of thing, information technology desegregate iris pro graphics 6200 cost. The massive 128MB L4 cache ( eDRAM ) equal a serious speak period a information technology bless the 5775C with the universe ‘s firm incorporate graphics solution .
The 6700K ‘s solution do n’t appear to beryllium about a elaborate, merely to constitute honest we sleep together little about information technology technical specification deoxyadenosine monophosphate no one astatine Intel oregon the praseodymium firm we deal with could answer any of our question .
besides read : about ten days of Intel central processing unit compare, from Conroe to Haswell
The public relations market substantial plainly induce mention of associate in nursing Intel HD artwork 530 solution that support DX12, extremist HD 4K resolution and operate on at up to 1150MHz. information technology ‘s say to constitute forty % fast than the HD artwork 4000 of the core i7-3770K, which be a bit random .
Intel suffice n’t provide united states with a die-shot of the 6700K, merely a far angstrom we displace tell the L4 cache be n’t featured on this model. GPUz reputation that the HD graphic 530 sport twenty-four european union, sixteen TMUs and eight ROPs. This be the same shape american samoa the iris professional 6200 discover on the 5775C, merely without the L4 hoard there plainly be n’t enough bandwidth available.
