Please forgive me that I had to stick to a small amount of benchmarking, simply due to the urgency of the matter. I considered it my responsibility to be the first that reports of a Pentium III processor, which is for once capable of running Sysmark reliably at a speed of 1.13 GHz and beyond.

You can see that the Tualatin-256 is not a whole lot faster than Coppermine when both run at 1 GHz. However, once overclocked to 1.42 GHz, the Tualatin-256 (as we christened it) is able to reach regions that are usually reserved for Athlon and Pentium 4 processors only.
The same as the above said is valid for the infamous NV15-demo run as well. A tuned Tualatin-256 is able to get close to today's high-end processors.
