Intel's next generation Kaby Lake architecture has been teased, but we haven't seen CPUs in the wild just yet - even though there are countless leaks on the new Core i7-7700K, and the latest one is the best.
The upcoming Core i7-7700K has been overclocked on a 100-series motherboard, with it hitting 6.7GHz thanks to LN2 cooling - and considering its stock 4.2/4.5GHz clocks for base and boost, respectively - this is the fastest Core i7 CPU from the Kaby Lake family.
HKEPC is behind the Core i7-7700K overclocked to 6.7GHz, where he used an ASRock Z170M OC Formula motherboard and GALAX HOF DDR4 RAM. The multiplier on the 7700K was upped to x67, while the bus speed wasn't touched. We don't know what voltage was used, but with HKEPC using LN2, we're sure it was pretty high.
Intel's upcoming Core i5-7600K was also overclocked, hitting a very respectable 5.1GHz on air, all done on the ASUS Maximus VIII Gene motherboard by facebookHK. The multiplier was increased to x40, while the bus speed was adjusted slightly to 127.51MHz, and the voltage set to 1.504v.
Intel has used its latest 14nm+ process node, with 8MB of L3 cache and a TDP of 91W - we should expect the Core i7-7700K to fall somewhere around the $370 mark. Intel's more mid-range Core i5-7600K is a quad-core processor on the same 14nm+ node, with 3.8/4.0GHz+ clocks for base/boost, respectively - while it has 6MB of L3 cache and the same 91W TDP, the price will be lower at around $250.
