with the current G4-revision - namely the 7455 - we are on 1.13Ghz RIGHT NOW!!! this is the reason why apple can deliver the dual G4/1Ghz in high quantities.
my Explanation:
the G4 in the 867Mhz-PowerMac (single-processor) was not fabbed with the SOI technology. fabbing on same die size (.18m at the moment) and with SOI will bring a speed increase of 30% which would be 1127 Mhz ...
a simple reason, why apple has enough of its Ghz G4s...
further on:
if motorola will begin to fab on .13m i expect at least another 40% increase (if not up to 60%) in Mhz speed (same pipeline architechture) ... this would result in 1127*140/100 = 1578 Mhz
about motorola:
it's not sure if mot can do SOI and 0.13m - the only company which is fabbing 0.13m with SOI afaik is IBM...
other thoughts:
the G4 has been around for 4 years now. question: how long did it take to get from the 604 and 603 to 750 and 7400 ? ... i can't believe that motorola can't get the next generation out soon... and this is why i hope for the G5 soon... and i bet it's in july (latest august )

No. I'm using something faster.

I also have a "low end PC", 1 Ghz P3. It's not faster, not even close. Perhaphs your "low end PC" isn't as low end as mine.

I'm just curious where these 40% to 60% clock speed increase expectation comes from, just from moving from .18u to .13u. IIRC, most references I've seen from places like Microprocessor Report (sorry, don't have the link handy) suggest something closer to 30%.
As for Motorola not being able to do SOI + .13u, this is absolute nonsense. Motorola's HiP7 process includes these two by definition.
