Bottlenecking a myth

post #1 of 38
Thread Starter 
I went to search 3dmark.com and interesting enough with a single GTX 580 in an i7 set up vs a core2duo run neck and neck except for the physics and combined test here are the results
--------------------------------------------------------------------------------

i7 E8400

GraphicsTest1 25.8 27.62 FPS


GraphicsTest2 27.2 29.03 FPS
--------------------------------------------------------------------------------

GraphicsTest3 37.94 40.29 FPS
--------------------------------------------------------------------------------

GraphicsTest4 19.27 19.99 FPS
--------------------------------------------------------------------------------

PhysicsTest 27.32 11.74 FPS
--------------------------------------------------------------------------------

CombinedTest 27.8 16.12 FPS

so what can be said about this I am actually shocked myself that the c2d was ever so slightly faster in the graphics tests ,, opinions?

The graphics tests are meant to rate the GRAPHICS performance of your computer. The CPU doesn't really affect that score by design. The overall score is what gives the entire performance of the computer, which is what matters and IS bottlenecked by slower CPUs.

The C2D probably does a little better in the graphics sections because the platform has less overhead.

The E8400 is not a slow or inefficient processor; its just an older one. Try that with a Pentium D 930 and then you will see your bottleneck.

Well in terms of bottlenecking I believe that if it were happening the GPU would perform poorly being that it's waiting for info from the CPU and that's clearly not the case here. However, when you check the sli results the i7 runs awayfrom the c2d . I think it's clear that a fast c2d can handle a single gtx 580 just fine !

Play BFBC2 or GTA 4 and then claim bottlenecking is a myth. There are some CPU dependent games you know.

Don't make me sad.

I have a 930.

when i gain 5 fps by getting a new processor, you think bottlenecking is a myth

At a low resolution a bottleneck does occur if the CPU isn't overclocked, but who is going to be playing at 1280x1024 now adays?

Bottlenecks vary from program to program. Depends on which part is a greater dependent.

This thread is so fail. OP you should probably just leave because you are going to get flamed so hard.

Anyway, to contribute something useful to this thread, benchmarks sometimes don't mean a whole lot in real world performances. (Unless you are one of the people who finger themselves while looking at benchies).This is a perfect example. That test you ran stresses the GPU only, its doesnt stress the CPU. Now, play a game like GTA4 or BC2, and you will see a huge processor bottleneck. To make the claim that CPU doesn't bottleneck FPS is completely outlandish.
