Intel’s next generation HEDT platform will be the the 7th generation Core i7 “Kaby Lake-X” family. The platform will be based off of the new LGA2066 socket and will make use of a new motherboard chipset, the Intel X299 express. This platform will succeeds the current Core “Broadwell-E” family processors which make use of the Intel X99 chipset.
The first chip on the X299 platform probably is not what you are expecting. It is actually the 4-core Intel Core i7-7740K. The chip lacks an integrated graphics core, but does have a wider memory interface. The TDP is 112W compared to the 91W of the i7-7700K.
It looks like someone with access to a Core i7-7740K installed it on an ASRock X299 Fatal1ty Gaming i7 motherboard and ran it through SiSoft SANDRA processor arithmetic and multimedia benchmarks. The chip does perform pretty close to the Ryzen 5 1600X, but falls short of the Ryzen 7 1800X.
