Individual cores on the 7950x are roughly twice as fast as what you have. If your work isn't massively multithreaded, then a 7950x will likely perform quite a bit better than a Threadripper 3970x. (Though of course you won't be able to get more than 128GB RAM.)
This is with clamping down TDP on the 7950x to roughly 110W. It's an absolute beast.
