Performance - Fill-rates & 3DMark

This is something we've never seen before. As we discussed, while Immediate mode renderers are theoretically capable of high fill-rates, they rarely achieve it due to lack of memory bandwidth and overdraw. Serious Sam offers a direct test of a card's actual fill-rate, and shows that the GeForce 2 line, while boasting theoretical fill-rates of 800 Mpixels/sec, is only capable of achieving around 300 Mpixels/sec in most cases. By contrast, the Kyro II is 100% efficient. The card is able to, in both cases, perform exactly as advertised, meeting the theoretical fill-rate head on. Now can you see the advantages of a small, elegant approach, versus a brute-force approach?

It shouldn't come as a surprise that the Kyro II falls behind in the 3DMark2000 and 2001 tests, particularly due to the lack of a T&L unit. The 3DMark tests are really a showcase for what nVidia cards can do, and while they may not give a great indication of performance in today's games, they certainly paint a great picture of performance in tomorrow's. It's clear that when it comes to T&L, and other futuristic features, the Kyro II is lacking.
