ICOMP 2.0 index comparison

The Intel Comparative Microprocessor Performance index 2.0 is a revised version of iCOMP index, which was used to compare performance of Pentium and earlier CPUs. Similar to the original version of the index, the iCOMP 2.0 is based on several benchmarks. However, since it is aimed at newer generations of processors, Intel made a few changes to how the final score is calculated. A priority was given to 32-bit applications, and Intel also included one multimedia benchmark, that tests imaging, video, 3D and audio performance. Benchmarks, used to compute the index, are CPUmark32, Norton SI32, SPECfp95, SPECint95 and Intel Media Benchmark. The iCOMP 2.0 index is scaled to the performance of the Pentium 120, which has a score of 100. Faster processors have higher iCOMP 2.0 scores. The Intel Pentium 166 MHz has an iCOMP 2.0 index of 127.

I don't know why, but the ceramic version overclocked easier. I ruined a couple of the plastic ones at ~200MHz, whereas the ceramic ones reached even 250MHz
