How does the Opteron compare with the Athlon64 FX in terms of gaming performance? The Opteron 2.0Ghz is comparable in price to the Athlon64 FX, which is 1.6Ghz, and the Opteron 1.8Ghz is significantly cheaper. I also use PCI-X slots. I'm thinking of getting one of the Tyan dual-Opteron motherboards with AGP and PCI-X and just getting one Opteron CPU (which I know I can do). However, I would like to hear some people's thoughts as to how the Opteron compares with the Athlon64 FX.

The FX-51 IS an Opteron, at 2GHz clock speed.

Oh... I thought there were some small subtle differences. Why do I see the FX listed as 1.6Ghz on pricewatch?

Thanks.

Nevermind, I see now that pricewatch listed the Athlon64 3200+ even though I clicked on the FX.

Would I be able to put an Athlon64 FX CPU in an Opteron motherboard then?

Yes, the two are compatible.

Also note that Athlon 64 FX requires registered memory modules.

Guess I'll plan on doing that then. Thanks.

Well...

The two are (AFAIK) based on the same core and fit in the same socket (Socket940). Both require registered memory.

I <i>don't</i> know if the Athlon64 FX will actually run in a multiprocessor config though. Also, I don't think Opteron does any memory speed higher than DDR333--and thus, I don't know if any dually Opteron motherboards will handle DDR400.

Just pointing that out, in case you were thinking of trying to build a dually with Athlon64 FX's. :wink:

more precisely: athlon FX 51 == Opteron 148 (both 2.2 GHz)
Opteron 148 isnt out though.
Also keep in mind you need an Opteron 2xx for SMP (8xx for >2 way). The FX and 1xx are strictly uniprocessor cpu's.
