Power4 a reality NOW
The Power4 is not a future chip, as some have suggested-- it's a working chip that is headed to production soon. It's not on paper, it's on silicon. It has AltiVec, no matter what they call it. The new chip looks like it's going to be a Power4.
The Power4 draws over double the power that a G4 does, even when scaled down for desktops. The new Mac can handle 4x the power consumption that they used to be able to, and have large heat handling capabilities. This indicates to me a potential for 2xPower4 Macs. It ain't gonna be before MWSF 2003, or possibly a February or March release-- but it's coming.
In the months after the Power4 Macs come out, you will begin to see lower powered Power4 chips for mobile computing. However, it looks as if the G4 will have a lot of life left in the iBook and iMac/eMac. Maybe even 2xG4's in the PowerBook.
It all makes sense. Who knows what they'll actually do-- but this is very promising. Keep in mind that they are part of the HyperTransport consortium, and have been working closely with nVidia. I think the motherboards we saw were possibly HyperTransport based Power4 capable Macs. What'cha think?
