The AMD Ryzen Threadripper Pro 3945WX is a 12-core, 24-thread workstation processor built on the Zen 2 architecture. It runs at a 4.0 GHz base clock with 4.3 GHz boost, and it sits on the WRX80 platform with 128 PCIe 4.0 lanes and 8-channel memory support. That platform is what separates it from mainstream desktop chips: it suits people running CAD, simulation, rendering and multi-GPU work who need lanes and memory bandwidth more than the highest clock speeds. Against newer Threadripper Pro 5000 and 7000 parts it is older silicon with lower per-core performance, so it makes sense mainly for buyers already on WRX80 or picking one up cheaply.
