Background on AMD Threadripper PRO CPUs
AMD's Threadripper PRO processors are designed for heavy workstation usage, and adapted from their EPYC server line. While core counts and clock speeds are similar to the normal Threadripper series, these PRO versions offer more PCI-Express lanes, more memory channels, and higher RAM capacities. Those advantages make Threadripper PRO a great choice for memory dependent workloads, as well as hardware configurations which need a lot of PCI-Express lanes.
These differences also require a unique chipset, which in turn means different motherboards. Threadripper PRO boards tend to be larger than standard ATX size, limiting their usage to full tower cases and rackmounts. Both motherboards and CPUs in this product line are also more expensive than AMD's mainstream models, but for applications which can utilize the extra bandwidth or memory capacity the additional price is well worthwhile.
