I've just bought an XFX Radeon 5670 1GB passive cooled card to replace my GeForce 8800GTS 320MB (less noise, less power usage). Like all good geeks should I decided to do a 3DMark Vantage test on both cards and was somewhat surprised to see that the 5670 scoring less than the 8800. I was expecting it to be at least equal, if not better, in most cases. This card has GDDR3 as opposed to the GDDR5 found in most 5670's, but I didn't think it would make too extreme a difference. Anyway, here are the results:
GeForce 8800GTS - GPU 4710
Ai Radeon 5670 - GPU 3657
GeForce drivers were uninstalled via Windows Device Manager before installing the Radeon and then installing the Catalyst drivers last. Windows is set to High Performance mode.
Sounds about right? Or should I be getting more?
CPU is a Core 2 Duo E6420 OC'd to 3.2ghz.
