The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15 CPUPro]

Skylake 6th generation Core i5 processor...

I am somewhat disappointed with the performance. It is a bottleneck for my GTX 1070, with the CPU maxing out at 100% during gaming such as Minecraft, Fortnite and Rust at very high settings. That being said, I did not overclock it, but am still annoyed.

Great IPC and at the time was the best gaming CPU available. Dinged a star as hyperthreading should have been a feature. Just a standard boring 4c now.

I have just upgraded from a gaming laptop (MSI GS70 2PE) to a Desktop PC. Such a good decision. I choosed the i5-6600K for it's price-performance factor (no one is surprised here). I paid less then €200 (bought with company, no TVA). It is overclocked at 4,5Ghz and cooled by a Corsair H80i V2. The average temp is 28°C and the highest temp I have seen was 58°C. All Adobe software open in 2 seconds. After effects never lags. I love it.

I was able to overclock to 4600 without knowing much about overclocking, using simple settings in my ASRock Z170M Extreme4. Runs very cool stock, using a Noctua NH-C14S, and only about 30 degC over ambient when overclocked and working hard. Wound up being perfect for my quiet HTPC/Gaming machine. I'm leaving it stock speed for normal use, with the ability to OC if I find I need it in the future, and to tinker and play with to see how fast I can get her.

A rock solid performer. Running a cheap AIO loop I feel pretty confident I can hit a voltage ceiling near thermal max and remain stable. Maybe I just won the silicon lottery but this 6600k is a barn burner.

Nice low power taking, overclocks very well even on air cooler with single fan without having high temps(60-70c while heavy gaming). Got mine to 4.5GHz at 1.35v(will tinker bit more to get voltage lower). 10/10 chip for just gaming. Love it

This cpu is amazing, really easy to overclock too. Got mine up to 4.5ghz using an auto voltage on a sup bar motherboard and it's 109th percentile. You can pick it up for 190 on sites like Jet when you use a first purchase promo. can't recommend enough.
