A new PassMark benchmark debuted a day after the Ryzen 5000 Threadripper dual-socket capabilities were leaked online, showcasing the full capability of two Ryzen Threadripper Pro 3995WX 64 core CPUs working in tandem — for a total of 128 cores. When comparing the overall score, the dual CPU configuration exceeds a single Threadripper Pro 3995WX by 44%, according to PassMark.
Oddly, we’re getting a dual Threadripper Pro 3995WX result. AMD never explicitly said or implied that two Threadrippers could coexist on a single motherboard. It begs the question of how the original poster was able to operate two Threadripper Pro 3995WX processors at all.
If AMD plans to release dual-socket Threadripper motherboards, it will offer up new possibilities for building powerful PCs. If you combine two Threadripper Pro 3995WX processors, you’ll have a total of 128 cores and 256 threads to deal with, which is far too many for any workload.
The possible doubling of memory capacity for Threadripper systems is another intriguing feature of dual-socket motherboards. This is because adding another CPU to a mainboard necessitates the inclusion of additional memory slots for that CPU to use. Theoretically, this can give you a maximum output of 16 memory channels on Threadripper Pro and a massive 4TB of memory capacity to deal with if your motherboard has the requisite DIMM slots.
We don’t know what’s going on here because AMD hasn’t announced anything about dual-socket compatibility for any Threadripper CPU yet. However, with reports circulating that dual-socket Ryzen 5000 Threadripper motherboards are on the road, AMD could be upgrading Ryzen 3000 Threadripper Pro to perform similarly, which would explain why this benchmark exists.
