3D performance

To make a long story short, the Guillemot Xentor (overclocked to 185 MHz core / 195 MHz memory) used in the test setup was a bit out of its league when dealing with the raw power of the Athlon and the K7V.

Still the scores are impressive enough to be shown here. Regardless of the CPU frequency, all Incoming benchmarks gave frame rates of 196.2 - 196.8 (no sound, memory at 4:3) the limit of what the card is able to push. With the memory set to 3:3, frame rates dropped to 186- 190 fps with VCM having a slight edge over SDRAM.

Quake3 Arena

Quake 3 Arena is an extremely good example for the performance impact of increasing the DRAM read latch time latency. Please keep in mind that the card used is a simple TNT2 Ultra and not a GeForce even though the numbers are in the same league.

Quake3 Arena Test 1.08 at 640x480 (normal) resolution at 8x107 (861 MHz) using either VCM (3:3) or HSDRAM (4:3), the latter at 0.5 and 2.0 ns DRAM read latch delay, respectively. Note the dramatic performance increase caused by a higher latency.

Quake3 Arena Test 1.08 at 512x384 (fast) resolution at 8x107 (861 MHz) using either VCM (3:3) or HSDRAM (4:3), same as above.
