i don't get the big whoop about the "supposed" PB update. 200 mhz FSB??? what can you do with that?
All the things you can do with current PB's, only faster?
Seriously, G4 is a fine CPU, true, it's FSB leaves a lot to be desired, but it's not like Apple could just put 533Mhz bus there or something. What they could do is to help the situation. bumbing the bus to 200Mhz does help. And doubling the L2-cache also helps, since larger cache mean that CPU needs to access the RAM less often, and most load on the FSB in mem-access. I have heard estimates that doubling the L2-cache reduces the mem-access by about 20%. Since most load on the FSB is mem-access, I would guessstimate that doubling the L2-cache eases the strain on the bus by about 15%. And the FSB would be about 20% faster. Combined, those would bring substantial improvements to the platform.
I read a review where they compared 2GHz PowerMac G5 to 2GHz PowerMac G4. And guess what? They were pretty close to each other. Even with it's uber fast FSB and uber-fast RAM, G4 held it's own against the G5. And that G4 was the model with 166Mhz bus and 512KB of L2-cache. 7448 should do considerably better. Hell, it might be faster than G5 is, clock for clock!
they need to get their stuff together. I won't even think about a PB until the mactels come out. by then they'll be up to 800mhz fsb and dual core...now THAT is a POWER book.
There is more to laptops and computers than mere CPU-power. If I had the money, I would MUCH rather get a PowerBook than some x86 laptop. PB is just so well designed and smooth, that it's simply better than any x86-laptop, regardless of the fact that it's CPU is a bit slower.
