Not a great deal to be honest. The Opterons tend to be slightly cheaper though and use newer steppings which can give higher overclocks, but other than that have the same specs and instructions etc.
Opterons are intended for Server use, but have been snapped up by enthusiasts.

I'm curious to see how well the 150 does. I doubt any better than the 148 or 146's. Probably same overclock limit. I do know that the CABGE steppings are being sold with them.

Opterons have 1MB cache, right? While normal A64's only 512kb...

With the single core processors, they are virtually the same.
Dual core procs are different though. It would be much smarter to buy an Athlon Dual Core, due to the fact it has twice as much L1 cache (128KB+128KB vs 64+64KB), which is very important.

Sun what are you talking about ? DC Opterons have 2 x 1MB L2 cache while DC Athlons have 2 x 512MB.

Edit: nevermind I thought you were talking about L2 cache.

No. With the exception of San Diego A64 cores, single core Optys have 1MB vs. 512kB for A64.

No. DC Optys and X2 both have the same 64kB + 64kB L1 cache per core.

Opterons are actually more expensive nowadays.

No, the X2's actually have 128kb L1 cache per core, which should definitely impact performance being that L1 cache runs at very high speeds...compared to L2 cache and system memory
