15 inch Powerbook faster than 17 inch powerbook?

I didnt even notice that, was to hard to take my eyes off the nice 17inch screen :D I cant think of a reason why the 17inch G4 would be slower than the 15inch? As far as I know both have the same subsystems, memory, HDD and processor. I can think that the increased motherboard size might have made for a difficult design in terms of electronic track length, but not the the point where it could make a big difference.
 
The bits in the 17" PowerBook are going to be larger and present more inertia for the processor to overcome.

Either that, or the 1% difference is just minor overhead from keeping a larger display updated.

fair enough, I was just a little shocked because its the 'flagship' mobile mac. I suppose I'll let this slip :D
 
Yet how come the 17" MBP shows faster results same places on the site against a 2.16 GHz 15" MBP?:confused:

we are just too astonishingly observant ;) :D

I mean enough to make even S Jobs cringe

I also though the increased size of the laptop itself would be the possible reason, never though about the display itself. Could that really be the reason? I know 1% isn’t that much, but I though quartz extreme was there for the very reason of keeping the graphics nice a fast while reducing the processors workload?
 
The tests for the two MacBook Pro models were performed two months apart, allowing plenty of debugging and minor improvements to sneak in. The latest 15" units could reflect those changes too, even if Apple haven't published new numbers for them.

On the bigger bits thing, I definitely made that up :) On the display sizes, sure, that can still make a difference. No matter how cool your GPU is, there are still bitmaps that need to be passed through the CPU.
