"I think this report also gives proof that Sysmark 2001 is totally unreliable in measuring system performance. it showed a 92% speedup with a 36% increase in CPU clock." The Sysmark does what it is supposed to do - to measure the _system_ performance. The result simply says that the performance of peripherals and memory is more important than the raw CPU speed on the Sysmark-selected set of applications. "This is, of course, physically impossible unless the measurement is faulty." If in your workload the CPU mostly waits for data from memory or for completions of disk transfers (or finishing polygons drawings), and you increase the overall system clock by 2x, your performance will also jump by about 2x regardless of CPU speed.
