Intel Xeon (Prestonia) SMT benchmarks vs. Athlon XP

Here: whiningdog.net

Interestingly, the dual system showed 4 cpus listed under Task Manager.

Here are a smattering of the Sandra benches:

2 x AMD Athlon MP 1600+ 1.4GHz....7744 MIPS..........3879 MFLOPS

Also included are CPU multimedia, memory bandwidth, and CliBench. Unfortunately, the latter doesn't include Athlons.

This version of Sandra has been patched in order to utilize SMT. It remains to be seen how real world software will be affected.
