AMD has announced and confirmed Threadripper 3990X which will be launched on Jan, 2020, with 64 cores and 256MB L3 cache (like Epyc 7742), but didn't reveal its working platform and price.
As indicated by the name "Threadripper", it should belong to the sTRX4 socket product line, which has 4 memory channels. So, a 64 core CPU working on 4 memory channels? This sounds crazy, 16 cores competing for 1 memory channel? What impact would happen on this design?
