My GTX 460 1gb arrived, who wants to see some bottlenecking? - Page 3

post #21 of 22
Here, I'll give you guys an example to illustrate what I'm talking about.

Observe the following FPS over time graphs from a run of the Crysis Assault_Harbor bench. I've purposefully run the IQ settings low enough that I can create some CPU bottlenecking on my system by removing my OC.

Now, it's takes a tiny bit of work to interpret this graph, because as you can see, the 4.0GHz run finished significantly faster than the 2.6GHz, so the two lines don't, um ... 'line up'. But look at the shapes of both. See how both have 6 peaks, and 5 valleys?

IOW, if you 'picture' the lines as being equal length (left to right), the 'shape' of each is very close to identical, and the height difference between each of the two lines is (probably) very similar throughout (the height difference representing the % reduction I'm referring to).

So this is what I mean by a '% reduction' being caused by a CPU BN, rather than a flat-out cap. My CPU being at stock (at these settings, on this game) will act as a significant bottleneck. However, nearly every frame is being reduced by a relatively consistent percentage vs. what I get with my CPU at 4.0.

Wow, those were possibly two of the most helpful and informative posts in relation to a question I've asked. I knew I would be getting an upgrade and an increase in FPS, but I wasn't sure how much, or how much my CPU would bottleneck it. I don't think I really have any CPU heavy games, like Crysis, so I know I'll be happy with my card when it gets here.
