AMD seems to think Athlon64/Hammer will sport 25% better performance clock-for-clock in 32-bit code than 32-bit Athlon chips simply because of a faster memory subsystem. Given that Athlon64 was delayed until September due to lack of tools and support, it is probably safe to assume that you can bring one home and immediately head off to recompile your old 32-bit code. I believe they delayed because Windows XP 64-bit is not yet ready; it seemed implied, at least. Opteron releases in April as planned. Reportedly OpenSSL on Hammer was much, much faster than the fastest x86 scores. Not suprising since Hammer is 64-bit. -Matt
