| Intel P4 Extreme Edition Cache Size Matters | |
| (Review by MS, October 11, 2003) |
Maxon's Cinebench is one of the most interesting benchmarks, especially when it comes down to memory utilization in the OpenGL benchmarks. However, it appears as if the algorithms used for ray tracing are somewhat different from what 3dsmax is using, first of all, Hyperthreading is making all the difference in the world, second, the additional cache really pays off as well.
CPU Benchmark

There is no doubt at all about who rules this benchmark, the Extreme Edition is without competition.
C4D Rendering

In C4D shading, the Extreme Edition processor pulls way ahead of the standard P4 but is outperformed by the Athlon FX-51

OpenGL Software T&L

Pretty much the same picture as above.
OpenGL HW T&L

It is rather obvious that memory bandwidth, including cache, plays a major role here. As a nicety, Cinebench actually generates the ratio between software and hardware T&L as the so-called OpenGL speed-up factor.
OpenGL Speedup

It is not surprising that the P4 EE takes the lead here, at first glance it appears somewhat odd that the P4 3.0 beats the P4 3.2, however, keep in mind that lower multipliers also mean lower latencies / CPU clock and, thus, the numbers fit right in.
