What customers say about "Details"

Intel Core i7-6700K Desktop Processor

It doesn't run hot even when under load and turbo boosts normally to 4.2 GHz automatically as well.
Got it at a good oc of 4.25 very fast and really good integrated graphics.
The onboard HD 530 graphics are awesome. This is a great investment and the core of a machine that will be kick-ass for years.
This is a super smart and solid option for gamers because of its high speed (4.2 turbo boosted) and unlocked allows you to squeeze even more free performance out of it.
Great CPU, really fast. Great socket.

Intel Core i7-7700K Desktop Processor

I like it very much. This is the fastest CPU that will fit in my Gigabyte Z170x Gaming 5.
The I7 7700k is a great CPU. Great socket. Easy to install.
Socketed in and started up, no issues whatsoever.
The 7th gen processors are so easy to set in place. I love the spring contacts on the sockets for them.
If you aren't planning using Windows 10 - Kaby Lake will not support previous versions of Windows natively.

What customers say about "Technical Specifications"

Intel Core i7-6700K Desktop Processor

I7 quad core processor will be more than enough muscle for any and all modern games, and probably leave your gaming rig sitting pretty years of games considering that games are much more gpu dependent.
This is a super smart and solid option for gamers because of its high speed (4.2 turbo boosted) and unlocked allows you to squeeze even more free performance out of it
Quad cores also allow worry free gaming performance while still being able to run other programs and not take a hit in performance when your computer is under a heavy workload!
Awesome cpu, really fast and good temperatures.
Seems to run hot, even with multiple thermal paste applications.

Intel Core i7-7700K Desktop Processor

Overclocks just fine from 4.2 GHz to 4.5.
The i7-7700K can be overclocked to a stable 5.1GHz with water cooling.
The i7-7700K first off very noticeably faster than my previous i5, I use this in my gaming build which I paired with an ASUS GTX 1080.
Performance on this CPU is great.
This is a great CPU for both gaming and productivity.

What customers say about "Cache And Memory Specifications"

Intel Core i7-6700K Desktop Processor

The CPU has 8MB of smartcache that is shared amongst the cores. This is much better than normal cache, it allows a program in cache to be shared with another core, when the thread jumps to a new core, without copying the data to another location in cache.
Fast processor when powered with a good socket 1151 motherboard and enough memory.I have an ASRock Fatal1ty Z170 board and 32GB corsair DDR4 memory as well as a smile on my face
Everything is faster opening and switching programs games are amazingly faster was surprised how much better they ran maxed out with this chip. But also this makes the jump to DDR4 so memory has been tremendously improved stock memory is 2.2Ghz to 2.4Ghz.
It works fast, stays cool, and the ddr4 memory helps things stay zippy.
Would have been nice to have 12MB or more of cache, but the cost would have been significantly more. For the price, there is really no downside to this CPU.

Intel Core i7-7700K Desktop Processor

Super fast and works perfectly with my Asus Maximus IX motherboard and G.Skill 3600 Memory.
Paired the 7700k with an Asus Apex using Trident Z memory. Great performance.
There are no problems with memory compatibility.
The memory runs great at full speed with this processor.
Unfortunately the maximum amount of memory is 64GB, which is not enough for my needs.
