As in, are there cache benefits to running a computation on these huge CPUs vs some overclocked 8 core beast? On AMD chip's (I just dunno about the Intel architecture), each chip is divided up into chiplets with their own set of cores and L3 cache. For these Threadrippers, those will be 8 physical cores, and 32MB of L3 cache. Each core can access the L3 cache within their own chiplet only. You'll need to dig into the enabled cores+cache arrangements for any particular chip you might be interested in to figure out what will be good for your workloads.
