ich bin mir nicht sicher, aber ich mein auf hardocp gabs mal nen artikel dazu
die cpus mit 512kb sind in der roadmap von amd vorgesehen und sollten irgendwie strategisch eingplant worden sein
amd kann nämlich einfach bei den cpus´bei denen die 1mb nicht so ganz funzen den cache auf 512 beschränken und somit trotzdem verkaufen
bin mir aber wirklich nimmer sicher
werd den artikel jetzt mal schnell suchen
hier der artikel

"AMD did also verify that the "new" core is 193mm2 in die size. This is the same size as specified on the original 1MB L2 Athlon 64 cores as noted here back in September of this year."
und hier der hauptteil
"We find it sort of odd that AMD would sell a crippled A64 3200+ to the public after all the hard work that has been put into marketing the brand and features. If AMD did in fact have a large volume of A64 3200+ CPUs that failed to pass muster with 1MB of L2 cache, but with at least 512KB of it operational, what would they do with them? We are suggesting that is exactly what we are seeing happen. AMD could very well be turning "dead inventory" in cold hard cash/cache. There is no reason for them not to do this and the 3000+ seems to fit right in the current line up although the specifications might be a bit confusing to the industry overall. It certainly seems to me that if AMD wanted to sell a 512KB Athlon64 to the public they certainly would not be using a 193mm2 piece of silicon to do it. I think that we will see a "real" Newcastle CPU show up with a decreased die size reflecting the room needed for 512KB of L2, not 1MB. Then also, maybe everything at AMD is going exactly according to their master plan."
klingt eigentlich logisch
