Dear CPU Scorekeeper

I have been studying very hard and closely on the AMD vs. Intel controversy of who's chip is faster. I would like to raise the question that you are providing false information to your web site readers, and you are telling them that the AMD Athlon provides better performance than the Intel Pentium III Coppermine processor, which is untrue.

The 1GHz Intel Pentium III Processor edges over the AMD Athlon 1GHz, as known on PCWorld.com; ZDNet has even said that as well. I would think you would change this existing information and provide people with the correct information.

I do not know where these tests come from that you do on the performance of both systems, but I would suggest you do not take it from one site.

All the scores listed on The CPU Scorecard are derived from published benchmark comparisons, as shown on our Benchmark Sources page. As such, they are not intended to be taken as a definitive measure of processor speed in all computing applications. Even the iCOMP scores (originally from Intel) should only be considered as an estimate of how a particular CPU will perform in most systems, most of the time.

If you check out the latest CPU reviews available for both the Athlon and Pentium-III at 1GHz, you will see that neither chip beat the other in every benchmark test. In the first published tests, the only Pentium-III systems that consistently beat the Athlon at 1GHz were those configured with RDRAM, rather than the more common (read: cheaper) SDRAM. It was from these results that the first CPU Scorecard scores edged the Athlon ahead of the Pentium-III.

As additional published tests have become available, including those you suggested, it does appear that the Pentium-III has a slight overall performance margin over the Athlon at 1GHz. The difference is so small, however, that this may change as additional benchmark information becomes available.
