What customers say about "Details"

Intel Core i5-6600K Desktop Processor

Its pretty fast, and the integrated graphics are doing wonder while I wait for my GPU to arrive!
Integrated graphics are actually doing pretty well. I am playing blade and soul with no gpu at high settings in 1080p and I get around 35-40 FPS.
Works like a charm. Runs real cool and got a good boost clock of 4.2 Ghz.
Great CPU. I'll overclock it when I get a water cooler.
Amazing cpu for gaming. Super fast.

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.

What customers say about "Technical Specifications"

Intel Core i5-6600K Desktop Processor

All i can say is that you can run games in 4k at over 60 fps and OBS rendering at 1080 at 60fps. Running mine at 4.8 ghz on all cores.
When I use Core-temp its free download to look how safe temperature during the game and its seem okay with almost less then 40c (104f) and its very fast processor.
I've had no issues with gaming, software, or any other tasks running on my PC.
I have had very stable temperatures using a Hyper 212 Evo. Would recommend this to anyone upgrading on a budget.
Standard Intel processor. I have not overclocked or adjusted this CPU. The temperature runs around 40C.

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.

What customers say about "Cache And Memory Specifications"

Intel Core i5-6600K Desktop Processor

Used this processor for my friends gaming build. Does the job great and is very fast and cool. Temps do not exceed 43 degrees Celsius on air cooling.
This processor very fast and easy to install, i like it. It worth it. I would recommend it. I am very satisfy with my purchase. I would buy it again. Thank you
I can't complain, this processor is fast and efficient. Right out of the box I was getting 3.9 Ghz without any overclock.
New DDR4 memory has been a disappointment too (but finally improving in price and clock speed).
Also Skylake CPU is overall no faster than the previous generation. New DDR4 memory has been a disappointment too (but finally improving in price and clock speed).

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.
