I don't know the nitty-gritty of why, but some compute intensive tasks don't benefit from hyperthreading. If the processor is destined for those tasks, you may as well use that silicon for something actually useful.

- bgnn 7mo agoYeah of you are running Comsol you need real cores + high clock frequency + high memory bandwidth. Gaming CPUs and some EPYCs are the best
- to11mtm 7mo agoIt's a few things; mostly along the lines of data caching (i.e. hyper threading may mean that other thread needs a cache sync/barrier/etc). That said I'll point to the Intel Atom - the first version and refresh were an 'in-order' where hyper-threading was the cheapest option (both silicon and power-wise) to provide performance, however with Silvermont they switched to OOO execution but ditched hyper threading.
