Exactly How Does a CPU Bottleneck a GPU? - Page 2

post #11 of 56
Here's a question: (Sorry for a little thread hijack... ) What processor should I get if I want to make sure that I don't bottle neck my 8600GT?

A single core at 3.00ish probably wont even bottleneck our GPU :-/

A e2140 at stock is insurance lol

What game, resolution, and settings.....


A Q6600 at 5GHz should do it.

Why 5 ghz? Should't he search for an ES so he can get the 17ghz needed to run sim city 2000?

"Bottleneck" is such an inappropriate term, but it's now become a catch phrase. A GPU always will perform at its fullest, no matter what it's paired with. The reason someone with a 3GHz X2 has lower frames in a game (or a benchmark) compared to someone else with a 3GHz C2D (both with the same GPU) is simply because one CPU is faster than the other. Benchmarks like 3DMark show this clearly; benching the above CPUs will give you drastically different scores, but if you notice, the GPU scores would be almost the same, while the biggest difference (and what determines the final score) will be the CPU score. People say 3DMark is too CPU dependent, but that is what basically happens when you stick a faster CPU in a system... the score (gaming performance) increases.
You need both components to game, a fast CPU and a fast GPU. Of course you got variables, like gaming at high resolutions depending more on the GPU, and so forth. However, the fact of the matter is that a slow CPU does not slow down a GPU, but rather a slow CPU slows down your overall perfomance, much like less or slower RAM or a slow HDD, would decrease your overall performance.
So do not bother breaking your head trying to figure out if a new card you're planning on purchasing will be "bottlenecked" by your older CPU. Just get the fastest card you can afford.

An e8400 at 4ghz most definitely does not bottleneck a 4870.

The term bottleneck is so overused.
