Why are the versions of the software used in this benchmark so old?

Surely all of these packages are faster now. Additionally, it appears to be done by the guy who wrote QEMU, so it's not exactly an independent benchmark.

A 667 MHz Alpha runs x86 code faster than a 500 MHz P3. This might not be a surprise to some, but it was for me.

It would be more interesting to present benchmarks that aren't this outdated. How do current versions of the software compare?

Qemu has changed a bit indeed but Bochs hasn't changed much since last year and Valgrind hasn't either (at least not in the simulation area that's been measured).

No no no... they are *native* alpha executables, and yeah the 666MHz Alpha goes about 150-300% faster than the PIII-500, but that is not at all surprising..

When emulating x86 under QEMU, you can see the alpha goes about 70-150% the speed of (ie. *roughly* equivalent to) a pentium 90.
