Details of Intel’s Core i7-7700K “Kaby Lake” processor have been leaked from a SiSoft Sandra benchmark. The leaderboard reveals some interesting details about the chip. It will be a quad-core part that will feature HyperThreading, so you will have 8 logical cores. The chip will be clocked at 3.60 GHz, with a TurboBoost frequency up to 4.20 GHz. This seems a bit odd as the current Core i7-6700K has clock speeds of 4.0/4.2 GHz. Keep in mind this is a pre-release engineering sample, so clock speeds may be different on production chips.
The IMC of the chip will be clocked at 4.0 GHz, and its integrated graphics core will have 24 execution unit, much like “Skylake-D”. The cache setup has been unchanged with 256 KB per-core L2 and 8MB shared L3 caches. “Kaby Lake” will be built on Intel’s 14nm node, which is rumored to be more energy-efficient than “Skylake”. “Kaby Lake” will be built in the LGA1151 package and will be compatible with current Intel 100-series and the future 200-series chipset motherboards.
“Kaby Lake” is the third mainline CPU architecture from Intel that is based off the 14nm node. We first had “Broadwell” than came “Skylake”. The first 7th generation Core processors could launch later this year.
