AMD X2 4800
asus A8N SLI deluxe
4Gb ram
Seagate Sata 200Mb
Nvidia FX3400

AMD64 FX53
Gigabyte motherboard,(I think)
4Gb ram
Seagate Sata 200Mb
Nvidia FX3000

Any ideas why the FX53 is twice, yes twice!, as fast as the X2 4800 ??

Twice as fast in which programs?
 
Oops sorry I forgot to mention that!
I use solidworks and ran 5 benchmarks.
Solidworks is a single processor program when used in it's basic form.
I had hoped that by putting all of the processes that I could onto the
second processer, Solidworks would have more processing power available.

I'm afraid I don't know Solidworks, but even if it's single-threaded, it
shouldn't be much slower on the X2 as the FX.

You have something badly misconfigured is all I can think of.
 
This machine was built by a professional system builder, (not by myself), so
you may be correct, lol
Any pointer of what to look out for?
Programs to use or something to compare any results too?

Contact the system builder.
 
This sounds like a chipset driver problem... the X2 will only run the same
performance at the worst and twice as fast at best.

It shouldn't be ANY slower. Aren't both 2.4GHz, 1MB L2 CPU's? Aside from
the second core, the X2 has SSE3...
 
Indeed.

Do you have /usepmtimer listed in boot.ini? X2 acts funny without
that. The best is the download the amd .EXE driver and install. The
..zip does not make this change.
 
It turns out that it is XP64 that causes the slowness!
I installed XP pro and the results came back almost even with the original
PC but a tiny bit slower.

AMD now has an .exe install for their CPU driver for XP64. Make sure you
try that. You can get it from www.AMD.com. It was only just updated, so
make sure you get the latest version for dual-core.

What software do you have for XP64 that is actual Win64 native?
