I was wondering, would a Dual-core with hyperthreading be twice as slow as a Quad-core?
It seems like it would, because it has to run 2 threads on each core.
Sorry I forgot to say for processes reqiuring 4 core, like a game. I should've been more specific
Hyperthreading won't give a exact percentage on how software will perform on it, including games. The performance increase will be from 0% all the way to 100%.
As you can see, it will vary a ton if you play a bunch of different games.
