So even at the same >clock rate, the Pentium II can run faster than the Pentium Pro. *Can run* being the operative phrase here. According to Intel's Web site: PPro-200, 256 KB L2 cache 8.20 SPECint95 PII-233, 512 KB L2 cache 9.49 SPECint95 So 15.7% higher SPECint95 at 16.5% higher clock rate. Personally, I don't want to draw any conclusions at all from these numbers - they are so very close. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
