G5 Specs for WWDC!

and PCI express wont be in the G5s anytime soon.

Really? What makes you so sure? It's an easy one for Apple, and deflects claims that their kit is old and moldy.
Apple's been a member of the PCI-SIG for a looooooong time

my two cents.....

i certainly hope you are right and the revision comes out at WWDC.
meself: i won't go for the top-of-the-line job, rather the step down from that (eg: the dual 1.8's in the current line-up, not the dual 2's) as this always seems to give the biggest bang for your buck.
i'll be interested to see if there are any major architecture improvements in the revision.
bring it on guys, these celerons i use for the biz are just driving me bonkers and WinDoesn't '98 really doesn't........

PCI-Express

If a PCI-Express x16 graphics slot is added I hope that Apple also upgrades some other I/O components at the same time. PCI-Express x1 based interfaces on the motherboard for USB, Firewire, and ethernet would likely significantly improve performance. A fourth PCI-Express x1 interface as an open slot might also be useful. The rest of the slots could still be PCI-X for now.

Could someone explain to me the difference between PCI-X and PCI-Express please?

PPC 975/980 at lower Mhz?

If the reason for delay is in achieving 3 Mhz at 90 nm, could we perhaps expect a PPC 975/980 to be released at a lower Mhz?

This answer will is in laymans terms..... So please dont flame me guys...

PCI-X and PCI are really the same standard....
except PCI runs at 100 to 133 MHZ both at 64 bit.
These connections are parallel connections(They r really hated b y motherboard manufactures because they require so many connections on the motherboards and are expensive to make)

PCI-Express is at its heart a serial connection... sort of like USB or Firewire(remember no flames please... corrections are ok though)
The main reason PCI-Express is so well thought of is it is very cheap to implement on the motherboards

Uhm...weren't normal PCI-cards/slots 33 (66 also?) MHz, and the PCI-X slots 100 or 133 MHz. Those are the frequencies in the current G5 lineup.

Yes that was a case of me not typing what my brain was saying...

What I meant to say was... PCI was 32bit 33mhz & 66 MHz whereas PCIX was 64 bit at 100 and 133 MHZ...

Thanks for pointing out that my post made no sense at all....

I hope you meen Ghz
