X2 or opteron - Page 2

post #11 of 25
I haven't been able to confirm this, but the X2 is supposed to have better memory performance than the Opteron. Supposedly, if you were to run an Opty at 334 x 9 against an X2 at 334 x 9, the X2's integrated memory controller will be faster. As the story goes, AMD makes Opterons with slightly slower memory controllers for slightly more stability in mission-critical servers.

I'd like to see some benchmarks that support this.

Opteron 165. Cheaper, better overclock, runs colder, better name. indignation above me is correct. Optys have slower memory controllers. I'd like to see you get a X2 at 3ghz though.

Also, it probably doesn't matter if you have your memory blazing at 278MHz

CPU MHz is the most important thing. With my memory at 260MHz i bet I rarely even use more than half of that memory bandwith, but I am fairly sure that I use all my CPU MHz alot

I plan to get an Opty 170 this month and move this 4200X2 to my server (Backwards I know, but it isn't that much of a server and its doing fine with a 3200 in it right now. I just want the Opty for the bigger L2 cache...though I don't see it making much difference but I figure it can't hurt).

There isn't a huge difference as long as you can pull off some good cooling. Some people have actually even had better luck with the X2 than the Optys.

Opterons will not always be better than every 64,x2,or fx, but the odds are heavily in favor of the Opterons.

Opterons may also cost a little more in price now. A 2.2Ghz 4400+ on NewEgg, which they don't sell anymore, cost $190. While a 2.2Ghz Opteron 175 cost $240. Bit of a price difference. You're paying an extra $50 for the option of the ability to overclock.
X2 4400 on Air is way too much to ask.Water yes,phase yes,air way to hard.

I've seen a X2's at 3.0ghz, and with water and phase cooling 3.2ghz.

3.0ghz is possible on air, but risky. I couldn't do it.

Hey whyifide what is your clock in your x2 4400?Sry dont want to mess your thread is only 1 question.
Edit.Ok is 2.6
