Please explain Opteron's numbering scheme

[Kenazo]

the Opteron 144 seems quite affordable now, around the low $300cdn mark. So, what kind of a speed difference is there between say the 142, 144 and 146 models? How does the speed compare to say A64 2800/3000/3200/3400? I realize they are for entirely different applications, so you don't need to point that out.


What FSB do opteron's run at? are they 166/333 or 200/400?


btw, I'm probably going to use it w/ an SK8V, and 1 gig of Corsair ECC pc3200 ram, with a Raid 1 36 gig Raptor set up.

There is a 200mhz difference between each Opteron. The higher numbers equal the faster processors. The 140's are 1.4ghz, the 142's are 1.6ghz, the 144's are 1.8ghz, and the 146's are 2.0ghz. They compare exactly with the same speed, 1MB L2 cache socket 754 Athlon64's, only they run their ram in dual-channel, which is useless for Athlon64's. Oh, and they're quite a bit more expensive, but that doesn't seem to make any difference to you.

Nope, makes no difference to me. For this application, the client says he wants ECC ram only. Thus, Opteron it is.

Thanks for the break down.

So, the 144 would be about the same as an A64 2800 in clock speed, but the A64 2800 has 512 megs ram, right? so probably close in performance to the 3000?
