I’m guessing the shader compilation stuff uses multiple threads. And as others are pointing out, be careful with what the single-threaded performance is like on a particular CPU architecture as well.
More generally, with AMD finally getting somewhere with the performance of some of their CPU’s, and Intel responding with a variety of additions and price changes to their range, coupled with a general trend towards game engines trying to make more effective use of multiple cores, we are perhaps at a point where advice may need tweaking. I havent had time to fully absorb all of the info about newer AMD cpu’s or what Intel announced in the last week but it feels like the CPU market may be having a bit of a shakeup.
