Opteron vs. Athlon 64?

What is the main difference between the two?

Thanks

Opterons can be multiprocessor (2-8 way). A64's aren't.

2XX and 8XX Opterons are 2 way or 8 way, 1xx Opterons aren't. 1xx Opterons
in 940 pin packages support registered DIMMs. 1xx Opterons in 939 pin
packages are just rebranded Athlon64s. The only difference is that all 939
pin Opterons have 1M caches, some Athlon64s have 1/2M caches while others
have 1M.

I think these are the basics.

Athlon64 - workstation chip, smaller CPU cache, no ECC support

Opteron - server-class chip, larger CPU cache, ECC support, support for
multiple CPUs (model #s: 1xx - single CPU only, 2xx - dual CPU capable,
8xx - quad/8way? capable). i.e. Opteron 246 is a CPU that can be used
in a 2-way configuration.

Both support dual-core now (Athlon64 X2s or Opteron model #s: x65, x70,
x75, x80 chips).
