Can a CPU bottleneck a GPU?

post #1 of 43
Thread Starter 
hi all,

i'm using a E6400 OC'd to 3.6ghz, but using a 7600GT OC'd to 650/800...

is it possible that the CPU is bottlenecking the gpu as i sometimes get a screen freeze almost as if the gpu is struggling to keep up with the cpu...

thanks...

Hmm.....good question. With that CPU and overclock i would say so. 1GB of ram could be the cause though.....that can be the largest bottleneck of all in a system.

a little bit yes, especially with that overclock you have, if it was at stock, it would probley be fine, but it shouldn't really be anything to worry about

Another 1GB ram and an 8800GTS would be an awesome improvement. The extra 1GB of ram alone gives a massive performance boost. I remember going from 1GB to 2GB of ram and i was shocked by the difference.

*** people?! That GPU will not be bottlenecked by the CPU in the least. I run the same setup but with an E6700 at stock (lower than his CPU overclock) and it does not load the CPU completely.

It's kinda odd seeing a 3.7Ghz core2 with a 7600GT.....they are a generation apart.

The CPU can DEFINATELY bottle neck a CPU, I was doing regular benchmarking while OCing and even on my e6300 (and 8800GTS) my 3dmark score went up around 2,000 marks from 1.8ghz to 2.7.ghz, then only 100 marks from 2.7ghz to 3.2ghz, this clearly shows a bottle neck.
