Intel’s new i7 and i5 CPU’s are aimed for gamers and overclocking.
The Core i7-6700K processor is a Quad-Core 4.0GHz beast that can be turbo boosted to 4.2GHz. With overclocking it can reach 5GHz. It has a large 8MB of L3 cache. The new i5-6600K is a Quad-Core 3.5GHz with 6MB of cache with a turbo boost to 3.9GHz. Both are part of Intel’s K (unlocked range), with many more Sixth Gen possessors on the horizon.
The pair of new Sixth Gen processors come with the new LGA1151 socket – meaning a new motherboard may be required. There is also the new Z170 chipset. DDR4 RAM is used. DDR4 is much faster than DDR3, but it does come at a much higher price.
