The Ryzen 7 1800X, Core i7-6900K, Core i9-7900X, and Core i7-8700K all hit very different clock speeds and offer different core configurations, ranging from the "classic" Intel HEDT
configuration (represented by the 6900K), the new Skylake-SP architecture with its larger L2 and small L3 (7900X), Intel's latest desktop CPU with its high core clocks (8700K), and AMD's Ryzen family.
To-date, all of the Core X chips we've seen and the HEDT
chips that preceded them were LCC processors.
AMD's Ryzen 5 1600X is a 6-core/12-thread behemoth at its $249 price point, so bringing six core chips out of the HEDT
market and into upper-mainstream configurations only makes sense.
Overall, AMD is gunning pretty hard for Intel with Threadripper, setting up one of the most interesting comparisons between the two companies' HEDT
(High End DeskTop) platforms that we've ever seen.
