In all four time-demo runs of Quake 3 Arena, different pictures emerge. In the first time-demo run, the Pentium 4 comes out ahead of the Athlon XP 2100+. Why? The Athlon XP lacks memory throughput, causing the AMD platform to bring up the rear. The NV15 demo-test is another story, though. The Athlon XP 2100+ outclasses the Pentium 4/2200. A hint - all Pentium 4 CPUs with an FSB clock speed of 133 MHz and 533 MHz Rambus memory that are not yet available on the market were marked with a blue-and-black bar and are there only for reference purposes.
