AMD is definitely not done with Threadripper. According to the latest reports the company is working on a massive 64-core, 128-thread Threadripper part which is set to launch in late Q4 of this year. A 64-core HEDT part would be pretty impressive considering AMD’s highest-core Threadripper part currently is the W2990X, which has 32 cores.
Right now it appears the platform AMD will be using will be called X599, although AMD is considering changing the name to avoid any confusion with Intel. AMD still does plan to retain the “99” suffix though. Since AMD plans to launch this platform in late Q4, expect to see motherboards popping up soon enough. It is not confirmed but this chip should use the same TR4 socket so current AMD HEDT motherboards should receive BIOS updates to support the new processor. We also don’t know if this is a 7nm part or a 14nm part trickling down from the server space.
You can expect this part to be anywhere from $2500 to $3000, which actually would make it pretty affordable based on the number of threads you would be getting. Intel’s 18-core HEDT chip is around $1800, so AMD could be really giving professionals a lot for their money.
AMD expects to have this chip ready for Q4 2019 as they have something else special planned for CES 2020.
