Are you sure ? this is not how I understood it.
I though something like:
Athlon "DT" = clawhammer (256Kb cache, 1 memory controller, single cpu operation, 2 (?) HT links)
Opteron DP = clawhammer (256 or 512 Kb cache, 1 mem controller, dual cpu capable 2 (?) HT links)
Opteron MP = sledgehammer (1 Mb cache, 2 mem controllers, glueless quad cpu support, 3 HT links)
I could be wrong though...

You are wrong; well, you forgot the word "glueless"; since Opteron has three HT links, it can support 4-way SMP without any external logic. But nothing stops you from creating a HT switch, and scale well beyond 32 way. Heck, Cray's Red Storm will use well over 10.000 Opterons, connected by a 3 dimensional HT mesh. This is in no way comparable to traditional beowolf clusters, and is a very strong testimonial of the flexibility and power of the hypertransport architecture. Its really like using lego blocks...
