ATI has finally put out a high-end card that is able to compete with the likes of NVIDIA and 3dfx. The Radeon features T&L and a good amount of DX8 support, but the card still wasn't able to out-gun the GeForce 2..
First surprise at Q3A: The underclocked Radeon beat our Geforce-1-DDR card! With a 12-percent-under-par frequency it couldn't compete with Geforce-2 and Voodoo-5/5500, though. Exception: At 1.600 x 1.200 and 32 Bit color depth it beat the Voodoo-5-5500, too.
Of course, we dont have any details on system specs or resolutions used etc, but a 12% underclocked card beating out a GeForceDDR card is certainly something worth investigating. here's a quick chart for comparison sake:
| Mtexels/sec | Bus Width | Memory | Bandwidth | |
| GeForce2 | 1600 | 128bits | 32mb(or64) | 5.2GB/sec |
| V5-5500 | 667 | 128bits *2 | 32mb *2 | 5.2GB/sec |
| Radeon | 1500 | 128bits | 32mb | 8.0GB/sec |
| V5-6000 | 1333 | 128bits *4 | 32mb *4 | 10.4GB/sec |
As was mentioned over the weekend, fill rate isnt everything. Memory bandwidth is becoming more of an
issue now that cards are running so fast and it looks like ATI at 8GB/sec (according
to their press release) is right in the middle of things.
update by Maarten: The guys at GA-Hardware got in contact with ATI about this preview, and it seems ATI isn't too pleased about it. They are saying
- ATI has not released any boards for testing. The testing was done on a board that was obtained through irregular channels.
- The A11 is at least two versions behind the RADEON that will ship.
- The shipping RADEON will have higher clock speeds and far more mature drivers.
- The board and tests used by Chip Online Review have no validity.
