It's not yet clear how exactly TR4+ will differ from TR4—rumor has it the configuration of the pins will be a little different. Nothing has been officially announced, though, so all we have are leaks, rumors, and speculation to go on.
Looking beyond the socket, this appears to be an extended ATX (E-ATX) motherboard, the same form factor as the X399 Aorus Xtreme. We can see four reinforced PCI Express x16 slots flanked by three covered M.2 ports, and eight DDR4 DIMM slots for quad-channel memory support. And of course RGB lighting is present.
Leaked Third Generation AMD Ryzen Threadripper Models And Preliminary Specs
- Threadripper 3990X: Either 48 cores and 96 threads, or 64 cores and 128 threads
- Threadripper 3970X: 32 cores and 64 threads
- Threadripper 3960X: 24 cores and 48 threads
We're speculation on the core and thread counts of the two higher end models, based on the starting point (24 cores and 48 threads on the Threadripper 3960X). If the leaked information is accurate, the Threadripper 3960X and Threadripper 3970X will both be available to purchase on November 19, while the Threadripper 3990X will make a retail debut in January 2020.
