Whats the difference between these two amd processors?

[Sniper991122]

I can't seem to find any benchmarks, but whats the difference between this Opteron 64 bit chip at 2ghz
http://www.newegg.com/app/ViewProductDesc.asp?description=19-103-430&depa=0
and this Athlon 64 3200+
http://www.newegg.com/app/ViewProductDesc.asp?description=19-103-416&depa=0

the are both at the same volts, both same operating frequency only difference is a $10 price difference and ones use the clawhammer core, other is using the Hammer core...

also i've 'heard' that the operton allows for ecc but the athlon 64 3200+ (not one of the fx's) does not?

can't find any benchmarks on these... any help?

also would the socket type matter? one is 940, other is 754... not sure if there are advantages to either..


edit - i've noticed that searching for socket 754 mobo's on newegg provided 35 results, however socket 940 on newegg comes up with 2 results...

The Opteron is a server processor with two memory controllers active. It fits Socket940 and current Opterons designed for Registered ECC PC3200 memory. The 200-series Opterons are dual-capable, and the 800-series are quad- and 8-way-certified.

The Athlon64 3200+ is a desktop processor using the same core but with just one memory controller active. It uses ECC or non-ECC PC3200 non-Registered memory and the current 3200+'s fit Socket754.

To skip to what matters: most home/enthusiast buyers choose an Athlon64 and unbuffered (non-Registered) non-ECC memory modules, and the popular setup is to get a couple of 512MB modules. The Athlon64 3000+ has been popular since it benchmarks very close to the 3200+ yet costs less. If you might want to run three or four DDR400 modules, 2GB to 4GB of RAM or need the industrial-strength stability of Registered ECC memory, then you probably should pick up an Opteron.

I have an A64 3000+ and unbuffered non-ECC PC3200. Not bad, but I wouldn't mind a dual-Opteron rig... :evil:

Does the FX Processor require Registered Memory and if so what is the advantage or reason.

It does, because it's almost identical to Opteron.

The FX requires registered ram, the opteron however must have registered ECC ram to run.

The FX is an unlocked chip, I'm not sure but I do believe the Opterons are also.

Something of note on the newer FX socket 939 processors coming out. They will not require the registered ram as in its socket 940 configuration.

Just fyi.
