If you have a computer that is not represented here or has a significantly different configuration, you might run the programs and send your results to the authors represented here. Please make sure that you include the relevant hardware configuration elements, the operating system, program run, Mathematica version, and the timing results.
Remember that benchmarks are highly variable and can depend on what other programs might be running on your machines and what you might have done previously in your Mathematica session. These numbers can provide you with a guide on what computers run what kind of calculations quickly.
Check out: http://www.heise.de/ct/english/9611270/ a German computer magazine's exhaustive comparison of the 200Mhz PowerPC 603e & 604e chips vs. 200Mhz Pentium & Pentium Pro chips (no MMX though). They benchmarked everything from Mathematica, 3D animation software, Photoshop, CD-ROM access to pure integer & floating point performance.
For an MMX comparison from the same magazine check out http://www.heise.de/ct/english/9701233/. . The all important graph is located at: .http://www.heise.de/ct/english/9701233/mmx.gif. It shows a 200Mhz 603e and a *150Mhz* 604e chip handily beating a 200Mhz MMX Pentium running MMX-optimised Photoshop filters.
In the Formula breaker section one finds:
Wolfram Mathematica 2.2.3 for Windows (95 and NT with a patch) and MacOS is one of the most widely distributed computer algebra systems. It has both symbolic calculations (the evaluation of algebraic formula) and numerical tasks (the "normal" calculation with numbers).
and a table showing comparative times. Interestingly NT is *much* faster than 95.
