Intel Core i7 and Core i9 "Skylake-X," Core i5 and Core i7 "Kaby Lake-X" Sell
Intel announced retail availability of its new Core X-series HEDT (high-end desktop) processors in the LGA2066 package, designed for motherboards based on the Intel X299 Express chipset. These include the 4-core/4-thread Core i5-7640X and 4-core/8-thread Core i7-7740X based on the "Kaby Lake-X" silicon; and 6-core/12-thread Core i7-7800X, 8-core/16-thread Core i7-7820X, and 10-core/20-thread Core i9-7900X chips based on the "Skylake-X" silicon. Compatible socket LGA2066 motherboards based on the X299 chipset began selling, too.
The Core i5-7640X features 4.00 GHz clocks with 4.20 GHz Turbo Boost, and 6 MB of L3 cache. The i7-7740X tops that with 4.30 GHz core and 4.50 GHz Turbo Boost out of the box, 8 MB of L3 cache, and HyperThreading. Both these chips feature just dual-channel DDR4 memory controller, meaning that you'll be able to use just four out of eight DIMM slots in most LGA2066 motherboards. The i5-7640X is priced at USD $242, while the i7-7740X goes for $339. These are the same prices at which you can buy the LGA1151 Core i5-7600K and i7-7700K, respectively, so an attempt is being made to transition all PC enthusiasts over to the HEDT platform.
