Well, I built my dual Opteron system.
MSI K8T Master2-FAR, MB
2x Opteron 246
2 gigs DDR
I haven't run any comparative SW benchmarks yet, but I did do some Mastercam
tests that involved a very complex 3D toolpath. This measures pure CPU
horsepower. The system I compared it against was a P4 3.2ghz, 1 gig ram,
Quadro 580XGL. Both systems had the same MC configuration with regards to
memory allocations to toolpaths etc.. Neither machine used more than 512mb
of ram. Graphics had nothing to do with the results.
The P4 generated the toolpath in 40 seconds. The Opteron did the same path
in 18 seconds. Now, before anyone gets too crazy, allot of this has to do
with th P4's inefficiency in running pure x86 code. Heavy floating point
tasks don't run well on the P4 unless the application is optimized for it.
Mastercam isn't, but it impressed the hell outa me anyway.
I did do couple of quick SW rebuilds of the same monster model on the two
machines. The Opteron still beat the P4. Not by 100% this time, closer to 25
A quick car analog. The P4 is like a Saab. Weeny little 4 banger turbo
tortured just this side of failure.
The Opteron or Athlon64-FX are like a Mustang Cobra.
Both cars are fast, but the Mustang is faster. The torque monster V8 doesn't
have to work nearly as hard, or spin as fast to get there either.
