Re: 64-bit: More than just the RAM
I'd just like to point out an inaccuracy in the article. The PowerPC 970, aka "G5" is a full 64 bit processor, based on the Power4. The G5 won't even run an unmodified 32 bit operating system, hence it won't run an OS X version earlier than 10.3. 10.4 introduced 64 bit kernel extensions (on a 32 bit kernel) and 10.5 full 64 bit kernel. It is correct however in stating previous CPU's (G4s, G3s) were 32 bit. |
