The processor specification sheets of the new Ryzen Threadripper Pro were published a few days ago and there is a new chipset, the Pro 695, which is on the list alongside the WRX90 and the TRX50. Only the five new Pro processors – which offer up to 96 cores – support these, neither the non-Pro processors nor the older Threadripper Pro CPUs list the Pro 695 as a compatible chipset.
The WRX90 offers Pro management and security features with more PCI lanes (total/usable) compared to the TRX50. It also supports up to eight memory channels, allowing a WRX90 workstation to scale to 2TB of DDR5 memory, twice as much as the TRX50. Both platforms allow the user to tinker with overclocking.
Considering that both the WRX90 and TRX50 launched at the same time as the Ryzen Threadripper 7000 Pro WX/7000 series, I believe the Pro 695 is either a mistake or a new chipset that offers yet-to-be-announced capabilities.
Could it be that AMD is planning to release dual-socket Threadripper Pro systems sometime in the future? Models that can offer up to 4TB of memory and as many as 192 cores. I’ve seen an increasing number of HEDT solutions powered by dual Epyc (including the 96-core 9654) – such as the Broadberry CyberStation Performancethe BisonZX6000G2 or the Titan S90 – so there is definitely a market for even more powerful workstation PCs.
