A couple of things to understand herejonwa said:What I don't understand is why a 32bit intel chip?
Why not go straight to 64 bit?
Isn't going from a G5 to a 32bit P4 a bit of a step back?
1) Itanium isn't hugely successful or standard, Intel's main focus is on x86.
2) SOME P4 (x86) chips are now 64bit
3) Intel is abandoning the P4 line and developing from the Pentium-M base
4) Pentium-M (originally mobile chips) won't have 64bit till Q1-2007
5) G4 chips are starting to have performance problems, G5 are not.
Add to that these facts:
- All Apple's laptops, and the eMac and Mac-Mini are G4 (32bit).
- Intel's Pentium-M plans are currently more laptop friendly (till Q4 2006?).
For these reasons, I believe it likely that G4 Macs will be replaced by Pentium-M (Yonah) Macs first. They get a performance boost switching to Dual-core Yonah, and they stay 32bit. When the 64bit (Pentium-M based) chips come out a year later the highest end G5s migrate to that. I'm not sure what the mid-range G5s will do (iMac and single processor powerMac), maybe they will drop to 32bit for a while?
