whats more important? GPU Clock, Memory or Shader?

post #1 of 19
Thread Starter 
right now my 8800GT is at 700/1050/1700
can i still push this thing a little further?

I do not have anything you could call a modern video card, but I do believe I heard people yielded the greatest performance increase per MHz by upping the shader clocks. If i remember correctly this was judged on acquired 3dMard06 points.

They all have a decent effect on performance

Start with Core clocks, shader clocks, then memory

Try up the core clock, will affect the speed performance
i think...

well, for my 8800GTX. i found upping the shaders clock gets more FPS in Crysis than Core, upping the memory clock doesn't nothing!

so i do it: shader then core then (if at all bothered) memory

but for 8800GT, i'd say core then shader then memory.
because GT have less ROP, so higher core will counter for that. and overclock memory is a must, because it doesn't have good enough bandwidth

memory rarely does anything I've noticed in terms of performance, only gives a slight edge.

from an ATI perspective, all that remains is the GPU clock which is really all I need to mess with, so I can't really say..... although the general consensus is gpu first then shaders

Perhaps it goes on a card per card basis. For my 8600GTS it was the core.

Core clock is the actual speed of GPU operates. The shader clock is the speed of the link between unified shaders such as vertex, geometry and pixel shader etc. They usually link to the core clock. That’s why you see in OC tool recommend tight them together. Memory clock is the speed of video memory chip. The good OC will be the good balance among of core, shader and memory clock so data won’t get jammed. Some games utilize shaders more so it will get performance boost as shader clock increases. The key is the balance. Otherwise, the score may be actually lower even GPU OC higher core, shader or memory clock.

Perhaps it doesn't show in the FPS, but in certain games I noticed upping the memory clocks makes the gameplay seem a bit smoother.
