We know it, ZEN 4 will also be available one day in the Ryzen Threadripper. AMD should also integrate its architecture into the TR 79xxWso for the HEDT models and in the TR 79xxWX for Worstations.
The former will be in 4-channel DDR5 and 64 PCI Express 5.0 lines while the latter will be in 8-channel DDR5 and 128 PCI Express 5.0 lines.
Then, we will have a 5 nm engraving and we expect 64 Cores and 128 Threads for the W versions and 96 Cores and 192 Threads for the WX versions.
Yes, but when ? Well probably in September 2023.
