Splitting Cores/Threads?

post #1 of 9
Thread Starter 
Just had a quick question that may sound dumb. Is it possible to allocate a certain amount of cores/threads of the i7 2600K for video encoding while leaving two left over for gaming?

You want to set the processor affinity like so, you could set the encoding software to use however many threads you want and then the leftover threads will be available.

Thank ya! I never knew about that function in Windows before...this will come in handy! Another quick question the second gen i7s are 4 physical cores and 4 virtual correct? If so will windows show the 4 virtual ones as well?

Yes they are quad cores with HyperThreading, so in task manager you will see 8 threads, and when setting processor affinity you will have 8 threads to choose from.

There is a possibility that this might have some effect, but I normally stagger my CPU affinities. As in, if I'm encoding, I'd assign Core 0,1,2,3,6,7 to the renderer, while leaving 4,5 to the game. That way it'll give the game at least one actual core to work with instead of two virtual cores on the off-chance you pick the wrong combo. That being said, I'm not entirely sure how much of a difference that makes, but its worth a shot.

Also, the above is not pulled out from my a$$, its something that I've noticed when I was monitoring the core usage one day. When turbo kicked in, it seemed to me that specific cores would turn off and boost power to the others. I decided that the ones that turned off were the virtual cores, hence my reasoning above.

You can also set your encoding to low priority as well.

But won't that completely stop/pause the rendering process if the game demands a lot of CPU power?
