Graphics Applications

Similar as in Sysmark2000, graphics benchmarks were all absolved without any anomalies, that is, no stuttering video or sudden loss of performance and, once again, the CUV266 comes out with numbers that could be beat only by a faster CPU (ok, flame me for this sentence if you wish).

About the only benchmark that caused problems at the higher clock frequencies was 3DMark2001. This is not too surprising since 3DMark is extremely heavy on the CPU, much more than on the memory bus. That the CPU is the most likely candidate for crashing at higher frequesncies is corroborated by the fact that, even slowing the memory timing settings to the highest latencies only allowed 3DMark2001 to run up to 159 MHz bus speed before the system started crashing again.

3DMark2001 score running at 5 x 154 MHz (770 MHz) and memory timing parameters set to 2:2:2

3DMark2001 score at 5 x 159 MHz (795 MHz) but this time the latencies were set to 2.5:3:3. If 3DMark scores were more affected by latencies, the relatively minor increase in bus speed would not be able to compensate for the higher overall latencies.
