I've been out of the loop for the last few months what's the difference?
Athlon64 (for the moment) = 754Pin, Single DDR Memory Controller, "Hammer" Core
Opteron (always) = 940Pin, Dual DDR Memory Controller - ECC/Registered, "Hammer" Core
Athlon FX-xx (now) = 940Pin, Dual DDR Memory Controller - ECC/Registered, "Hammer" Core
Athlon FX-xx (soon) = 939Pin, Dual DDR Memory Controller, "Hammer" Core
dont forget about the athlon 64's that will also be s939, its not just for the FX.
Notice, I said "for the moment".
In the long run (ie, 6 months from now) the distinction will be less obvious. Athlon64's will never have ALL of the following:
1) Dual Memory Controller
2) 1MB L2 Cache
3) Highest MHz rating.
So where as the latest FX chip may have all three of those, an Athlon64 will never have all three. So some Athlon64's will be 754pin (Single memory controller) and some will be 939 Pin (dual memory controller).
so is the optetron a consumer chip or supposed to be a server solution?
also what is up with the new btx form factor?
Opterons were designed to be Server chips -- hence the need for ECC/Registered Memory. However, the Athlon64 FX-51 is really a repackaged Opteron chip, so make your own choice. I am running an Opteron x48 chip in my desktop right now for example.
