epic1337 yeah, CPU has a lot of execution resources, a few of those could be occupied which will show 100% CPU usage, but other execution resources remain idling.
this is where SMT gets its performance increase in very well multi-threaded applications, the assigned threads in SMT can occupy more of the idling execution resources.

Show an example of that happening.

Operating systems are SMT-aware, and will load physical cores first and SMT only slips in work when there are ALUs/FPUs available for use in the core. "100%" does not mean the entire core is actually in use.

This is not going to happen on the 8700K.

SMT4 is the same, makes sense for server farms, not for gaming

They combined 4 Cores CCX to 8C CCX that itself is a big leap. There might be alot of others minor optimization which add up to pretty big gains.


All in all, the latest improvement will definitely help in games and we could possible see >10% more FPS compared with Zen 2 (with everything considered). That could possibly be just enough to edge out the 9900KS.
