Intel Kaby Lake-X i7 7740X and i5 7640X

Intel’s direction for the high-end desktop space has taken an interesting turn. After several years of iterative updates, slowly increasing core counts and increasing IPC, we have gotten used to being at least one generation of microarchitecture behind the mainstream consumer processor families. There are many reasons for this, including enterprise requirements for long support platforms as well as enterprise update cycles.

Until Kaby Lake-X-specific motherboards come to market, it’s best to either upgrade your GPU or take the full step up to a true HEDT processor.
