Until very recently you would be correct.
There were socket 940 Opteron 1xx CPUs and socket 939 A64's
Now they are releasing single Opteron 1xx's in 939 pin config.
Main difference is that they do not require REGISTERED memory.
They DO support ECC.
Other than that, what other significant differences between A64
andOpteron are there that matter here?
They do not need additional HT links as they are not SMP 2xx or 8xx CPUs.
