An unlocked 18-core Skylake-X refresh Extreme Edition desktop processor with Hyper-Threading and four-channel DDR4 memory for LGA2066 enthusiast systems.
ComputerBase found worthwhile gains in some heavily threaded applications over the 7980XE, but criticised the small overall refresh and price against Threadripper. Puget’s Premiere Pro 2019 tests found a modest export improvement with almost unchanged live playback. Both see limited reason for owners of the previous flagship to upgrade, with value depending on the workload.
Skylake-X refresh; Hyper-Threading and an unlocked multiplier, confirmed by Intel’s exact-model launch table.
