The GeForce 9800 GTX and 9800 GT swept our performance tests with 4xAA. Even the 9600 GT put up a surprising showing against the Radeon 4850, running neck-and-neck with the ATI card in our testing. We have a feeling that drivers may be playing a role in the 4850’s performance, as the card should be performing closer to the 9800 GTX rather than the 9600 GT. For instance, the Radeon 4850 runs 19% slower than the 9800 GTX at 1600x1200. Likewise, ATI’s Radeon 4830 performs closer to the 8800 GTS 640MB than the 9800 GT it’s intended to compete against.
At the lower end of the mainstream segment, ATI’s Radeon 4670 finished 4-10% behind the GeForce 9600 GSO.
Over and over again we’ve seen ATI’s 4000 series GPUs put up very strong 8xAA performance. Let’s see if that continues for the cards we tested today.
