The reasoning is the following if 6 cores 12 threads is the sweatspot in current games and 8C16T isn't bringing that much on the table then the question you can ask is: if 12T is what current games like what if I give each thread its own core.
Advantage: (if the game really only uses 12 threads)
- Cache isn't punched out by the other thread, so act a bit like it has more (game)cache.
- The threads don't hinder each other that much.
Disadvantage?
- If the game likes more than 12 threads it may slow down when going from 24 to 12. I assume if off is better now in the (far) future more games may like it on to beat an 8C16T
- 12C12T uses more power than 6C12T (but since 9900K we don't care ) but it most likely uses less power per core than the 6C12T
Yeah I see you thinking what does that mean for 3950X 16 cores for games...
Note that setting SMT to off on an 6C12T to 6C6T will probably cost you if the game likes more than 6 threads. (most games I would think)
There is a video out there that doesn't mean much (and could be manipulated) since it compares the 3900X with another system instead of SMT on vs SMT off of the same system (we are waiting for those test)
Compared to 9900K stock, but who uses 9900K stock?
