Re: AMBER: Opteron vs. Xeon performance

I ever did some tests for IBM new Xeon Blade, and compared with my "homemade" Opteron workstation.

Molecular Dynamics
Software: Amber 8 with all patches
Compiler and LIB: Inter Fortran 9.0 with IMKL8.1
Parallel Environment: Intel MPI 2.0

Intel Xeon Dual Dual-Core 3.2GHz
Simulation time: 100ps CPU time: 467min speed: 0.214ps/min

AMD opteron 275 (2.2GHz) Dual Dual-Core
Simulation time: 5000ps CPU time: 22571min speed: 0.222ps/min

Speed: Intel:AMD=1:1.03

AMD is a little bit faster.
