Is my CPU bottlenecking my GPU?

zandergunn · Feb 21, 2014

Hello, my bad if this is the wrong section to post this but I was really confused and needed to know. So I have:

EVGA GTX 465 4gb vram
Intel i7 950 @ 3.06ghz
6gb ram

I was wondering this because my friend had suggested to me unparking my cpu cores, which I did. When play arma 2 dayz, I noticed a 20-30 fps drop. When I parked my cores, it went back to normal. I was wondering if I was in the wrong with something I did, or it was my CPU bottlenecking. Thanks.

Well it seems like unparking the cores definitely hurt your FPS. I'm not sure why, it shouldn't have any FPS change for ArmA 2 honestly.

The only thing I can think of is that by unparking the cpu cores, the temperatures went too high and the CPU was throttled.

But no, I don't see how your CPU could bottleneck your GPU, especially not after you unparked cores

Try monitoring the temperatures after you unpark it while in game, let me know what they are.

Thanks for the reply, I've always got speedfan running in the background and when I had my cores unparked it was running around 55-60 degrees and parked it runs around 50-53 degrees. This is overall CPU temp btw, not individual cores. My GPU stays around 50-60 in game and both drop to around 38-40 idle.
