What processor is better? The Athlon X2 64 or the Opteron?

The 4400+ cost the same as the Opteron 175. Bought are 2400MHz, 2x1MB.

probably bout the same performance but the dual core gives you some great, great multitaksing

The Opteron would require a server mobo, registered memory and probably costs quite a bit more than the X2.

Get the X2. Registered RAM is slower and this way the only thing you're changing is your CPU instead of the entire system.

Tough choice; both run at 2.2GHz and have 1mb L2(both dual core..pretty much the same chip lol). I say go for which ever is cheaper unless the Denmark(opteron) is known to OC better than Toledo(X2)

Edit- Both are socket 939 so they wont require any fancy memory or mobo:)

Whoa...what the hell? Since when are Opterons socket 939?

And the X2 is about $30 cheaper on NewEgg...

Yeah. I'd like to know that too. I just noticed the other day when I was looking on Monarch and their combo is labeled socket939 sempron/athlon64/opteron 100 and I was like.. "what? how'd they sneak that by me?".

I'd go for the X2 as well. I doubt they're completely identical and the difference may be better for multimedia, same way the FX at the same clock is slightly better than the X2.

I guess for the 100 series, it may as well be socket 939 since you can only have one of them, but still, I thought the entire point of a server CPU was for ECC memory support.

The new dual core Opteron's are s939 and are known to be great overclockers. The Opteron 165 (1.8Ghz) for example can be had for under $300 and has been known to run @ over 2.6ghz on stock cooling.

I guessed the Opteron OCed better than the 4400+, And as I said, they cost the same over here, except that the Opteron is OEM and the X2 Boxed.

So Opterons no longer require registered RAM? How did I miss this?

1xx Opterons are now available for socket 939 and socket 940.

Socket 940 CPUs require registered/buffered and can do ECC and non-ECC.

Socket 939 and 754 CPUs, including Opterons, require unregistered/unbuffered and can do ECC and non-ECC. Most mainboards do not support ECC, but you can still use ECC modules, there's just no error correcting happening until you get a board that does (e.g. most Asus boards).


The early Opteron 939 14x have been great overclockers, with later one partly spotty. The early 1[67]x also seem to overclock great but insufficient data is available yet.
