Subject: CCL:dual-core Opteron 275 performance
Date: Thu, 30 Jun 2005 23:00:42 -0700 (PDT)
To add to the discussion about the performance of new dual-core
processors for computational chemistry applications,
the comparison of Intel and AMD dual-CPU based computers is shown at:
http://www.sg-chem.net/cluster/
As can be seen from the graph, the Gaussian 03 execution speed (test job
397) on dual-core dual-CPU Opteron 275 workstation is faster by a
factor of
1.95
as compared to the dual-CPU Xeon 3.2GHz 800MHz FSB machine.
-----------------
I would like to thank Ed Gasiorowski (AMD) and Mike Fay (Colfax
International) for their support.
