| 64 bit vs. 32 bit in Tiger
So, this is confusing me. I understand that Tiger will NOT support 64 bit on 32 bit systems, but the thing that's bugging the crap out me is the fact that the iMac G5 supports 64 bit in Tiger, but here's the thing I thought only DUAL G5 processors support true 64 bit. Cause an iMac G5 has only one processor hence it's only 32 bit unless, it's a single 64 bit processor. Anyways anyways anybody here running an iMac G5??? Next to a Dual processsor Powermac G5??? cause it seems that to me 64 bit is two processors, such as 64 bit AMD's processor which has two processor's. Anyways I hope my ponit is across, which is an iMac G5 has only one processor so how is it 64 bit??? Also some powermac G5's have one processor too so how does this work out???? Thanks for your time   |

a single G5 is a 64 bit processor

You can still do some 64bit operations on a non 64bit CPU but it takes longer to process.

OK stupid question then- Is Tiger going to be 64 bit? Or can I still run it well on my G4?

And no it won't run in 64bit mode on a non 64bit computer. Parts of the OS and some applications will make use of a G5 if you happen to have one, but for everyday use, it's a bit like the G3's lack of a Velocity Engine aka AltiVec compared to a G4 kinda step. The only real changes in requirements for Tiger are a DVD drive and 256 MB RAM (if Panther really asked for only 128, that is, although I'm not sure about that, I guess you can still install OS X on a machine with 64 MB RAM without Classic - just like with 10.0 - but you wouldn't possibly WANT to...).

In what way does the 64-bit support in 10.4 differ from that of 10.3? As I understand it, 10.3 has been running on 64-bit processors for quite some time, so I'd be surprised if there is not 64-bit support already?
