Hmm... the same presumptions would go also with the Celery-D processor, as it also has half or a quarter of the L2 cache size the Pentium-D has. Just add more power consumption and heat dissipation problems :D > My guess is - AMD64 is better on servers that have little chance of > running 32-bit binaries? They're good on both - as a 32-bit platform math computations are done using the wide registers and not the horribly outdated x87, thus the unintended, fortunate side effect of being faster. As a 64-bit platform it effectively dispels the law of diminishing returns when accessing more than 4GB of memory via PAE in current 32bit architectures (I'm not sure if apps are still limited to 4GB of addressable space in 32bit mode, as a 64bit machine should do away with that). The catch though is you'd need more memory, as the footprint's usually twice the size. -- Paolo Alexis Falcone [EMAIL PROTECTED] _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
