Intel is readying a refresh to its "Basin Falls" HEDT platform (LGA2066 client high-end desktop), with a new 22-core silicon. This part is neither Skylake HCC (20 tiles, up to 18 cores) nor Skylake XCC (30 tiles, up to 28 cores), but a new die with four more tiles than the Skylake HCC silicon, all of which are cores. The new silicon could let Intel design 20-core and 22-core SKUs for the X299 Express chipset, and is seen as a direct response to AMD's 24-core Ryzen Threadripper II processor, which was recently shown beating the 18-core i9-7980X in tech demos. The 32-core Threadripper II could face competition from the 28-core HEDT processor Intel is readying for Q4-2018, but that processor won't be compatible with LGA2066.
In related news, the company is giving finishing touches to a new 8-core "Coffee Lake" die for the mainstream-desktop platform (LGA1151 socket, 300-series chipset). This die features 8 cores, and likely 16 MB of shared L3 cache, while retaining the iGPU and uncore components from the existing Coffee Lake-S die. The chip could retain the classic "Ring Bus" design. The new 8-core mainstream-desktop SKUs, and at least two new high-end desktop SKUs (20-core and 22-core), could be launched in September 2018. The "Basin Falls" refresh, coupled with the new LGA3647 "Purley" derivative for the 28-core monstrosity, will be all Intel has to face AMD this year, with the company's next HEDT silicon, "Cascade Lake-X" being reportedly delayed to the second half of 2019, probably due to foundry problems..
