PowerMac Dev Notes

[arn]

Apple posted a Developer Note PDF (http://developer.apple.com/techpubs/hardware/Developer_Notes/Macintosh_CPUs-G4/PowerMacG4/pmg4.pdf) for the new Speed-Bumped PowerMacs.

Overall specs have not changed significantly from previous Quicksilvers, but is still a good resource for interested users.

[mischief]

G4 Processor: 32 Bit
Processor Bus:64 Bit
Memory Bus: 64 Bit
AGP Bus: 32 Bit
PCI Bus: 64 Bit

Okay so the chip isn't............

But the majority of the machine is 64 Bit. This means that the Quicksilver board is very close to G5 ready.:D

Anyone find it funny that this developer's document lists the single processor specs as "733 or 933 MHz"? What happened to the 800 MHz? :confused: This isn't just in one place, but throughout the document. And how do you get "128 MB of display RAM" from the graphics card (singular)? This seems almost as fishy as the supposed OS 10.2 movies release a week or so ago.

maybe the 800 MHz Model is not a G4 Apollo and therefore not included?
First leaked details of the GeForce 4 reported the top model having 128 MB DDR-RAM... so this is INCOMIIIING!!!!

Table 3-5 on page 40 shows the CD-R write speed of the 104 SuperDrive is 12x which I believe is a 50% increase from the A03's 8x write speed.

There's only two usb ports on the schematic as well, I thought there were four.

All macs have dual channel USB that means two separate pipes up to 12mb (128 devices) any other usb ports on the machines are just hub ports from the main bus
