ATI's Radeon 9500 Pro

Overclocking

We quickly discovered that the Radeon 9700 Pro was an excellent overclocker, but what about the newcomer Radeon 9500 Pro?

With Powerstrip 3.20 at our disposal we tried to push the Radeon 9500 Pro as far as it could go; our particular sample behaved quite well and granted us a 27% GPU overclock and 17.6% memory overclock (351/635MHz).

You should note that this may not be representative of the capabilities of final hardware, but the overclock we attained was within our expectations for the core.

A 12% boost from overclocking at 1024x768 isn't bad at all.

Overclocking the memory comes in handy at higher resolutions which is why we see an 18% gain here.

The performance gain finally tops off at 1600x1200 with an 18% increase due to overclocking, not too shabby.

In very CPU bound situations, increasing the GPU or memory clocks won't help at all which is why we see relatively no performance difference in any of the Botmatch scenarios.

Once again we have a very CPU bound benchmark where overclocking doesn't buy us much:
