PRO

AMD today announced that the Ryzen Threadripper PRO workstation processors will be directly available for purchase from March 2021. Until now, the processors were exclusively available as options for the Lenovo ThinkStation P620 workstation. The processors are being released alongside a small selection of compatible motherboards by ASUS and GIGABYTE. The Threadripper PRO processors are built in the sWRX8 package, and compatible with the AMD WRX80 chipset. From what we can tell, these processors are not compatible with sTRX4 motherboards.

What sets the Ryzen Threadripper PRO apart from the regular Ryzen Threadripper 3000 series is that it's a fully unlocked "Rome" multi-chip module re-configured for the workstation, with up to 64 CPU cores, 8-channel DDR4 memory, and 128 PCI-Express Gen 4 lanes. In comparison, the Ryzen Threadripper 3000 chips only feature 4-channel memory, and fewer 72 PCIe Gen 4 lanes from the SoC. The PIB (processor in box) retail package of the Ryzen Threadripper PRO looks rather plain compared to the PC enthusiast-focused Threadripper 3000, with a simple paperboard box that packs the processor, an Asetek AIO CLC adapter, and a spring-loaded screwdriver that's tuned for the sWRX80 socket.

I wonder when they'll change the socket again. Next or the generation after next. Most likely the latter, to not anger people too much. DDR5 will be a perfect excuse.

Real hutzpah

Normalized die cost for 64 core CPU is about 1.4x than for 16 core CPU (as it also include GF io chip die).

Just feel that AMD is doing.

As this guys already can move 48 core to 64 core into mainstream market (<$500 CPUs).

This is why capitalist must be hanged.

Short summary - software optimization for such number of cores sucks.

Memory also can pose additional problem as AMD in last moment disabled half of the channels due to fear that they won't be able to solve newer models.

IO Chiplet - same as in Epyc but laser specially disables half of it (4 of 8 memory channels and half of PCIe lines).

Yes, say thanks to AMD friends, technically it has NO reason at all (except slightly more profits for MB vendors).
