Intel Launches the Skylake-X Platform

Intel launched Skylake-X processors in 2017 for its high-end desktop platform, offering far more cores than mainstream consumer chips. The Core i9-7900X started the line with ten cores, and Intel later announced models reaching eighteen cores.

The platform introduced a mesh interconnect in place of the ring topology used by earlier many-core desktop parts. As core counts grow, connecting every core efficiently to caches, memory controllers, and I/O becomes increasingly difficult, so interconnect design becomes a major part of CPU scaling.

Skylake-X arrived just as AMD was returning to serious competition with Ryzen and preparing Threadripper. That rivalry pushed workstation-class core counts down into enthusiast desktops much faster than Intel’s previous roadmap had suggested.
