Showdown with 8x FSAA

Geforce GTX 295 vs. Radeon HD 4870 X2: Benchmarks with 8x anti-aliasing

As Nvidia's new Geforce GTX 295 beat AMD's Radeon HD 4870 X2 in the first PC Games Hardware preview, people wanted to have results with 8x anti-aliasing. The following test will reveal if AMD's flagship is able to win against the Geforce GTX 295 when running games with 8x FSAA.

Geforce GTX 295 - Benchmarks with 8x anti-aliasing: Introduction
In our GTX 295 preview we only tested the gaming performance of the card with up to 4x FSAA. But since AMD introduced the HD 4800 series 8x MSAA is often used for benchmarks, too. Therefore we decided to test the Geforce GTX 295, the Radeon HD 4870 X2 and the Geforce GTX 280 with the higher anti-aliasing mode.

Geforce GTX 295 - Benchmarks with 8x anti-aliasing: Game roundup
With 4x FSAA the Geforce GTX 295 is far ahead in Call of Duty: World at War (dt.) and AMD's X2 is just as fast as the GTX 280. Running at 8x FSAA the two Geforces lose more ground than the Radeon which can beat the GTX 280 - the GTX 295 is still unreachable though. In Crysis Warhead running in DX10 mode the results become even more interesting: While the GTX 295 dominates the competition with 4x anti-aliasing, it has to suffer a noticeable performance disadvantages with 8x FSAA like the GTX 280. Therefore the Radeon HD 4870 X2 is able to beat the GTX 295 at 1,920 x 1,200, but with only 15 fps the game is unplayable slow. The GTX 280 is too slow for those settings in general. Fallout 3 is almost fully limited by the CPU, but the GTX 280 loses ground with every resolution increase. While the HD 4870 X2 delivers about 60 fps at 2,560 x 1,600, the GTX 295 is stumbling and drops to the level of the GTX 280. Far Cry 2 is accelerated to more than 50 fps by all three competitors if running at 1,680 x 1,050 with 4x FSAA, but with 8x FSAA the GTX 280 and -surprisingly - the HD 4870 X2 are losing ground. At higher resolutions this gets more intense: at 1,920 x 1,200 the X2 is only slightly better than the GTX 280 and drops to unplayable 14 fps at 2,560 x 1,600. If you are playing Far Cry 2 with a Radeon you better don't use 8x FSAA. Left 4 Dead (dt.) runs smooth on all cards at 1,680 x 1.050 and 19,20 x 1,200 with 4x and 8x FSAA, although the Radeon X2 deals a bit better with the latter settings. But at the typical 30 inch display resolution of 2,560 x 1,600 the GTX 295 is up ahead and the GTX 280 drops to a limited or even unplayable performance level.

Geforce GTX 295 - Benchmarks with 8x anti-aliasing: Conclusion
The Geforce GTX 295 is victorious in the five games with 4x and 8x anti-aliasing. The advantage of 25 percent with 4x FSAA is decreased to 18 percent with 8x FSAA, but the difference to the HD 4870 X2 is still noticeable. The Radeon prevails in at very high resolutions only, but this is almost irrelevant because the actual fps are too low.
