Why would a dual TiBook be so unlikely? With duals power management could switch processors back and forth to save on battery use as well as solve heat build up problems. Additionally, the greater surface area of two processors would make heat dissipation easier to deal with.
<strong>I find it odd that an Apple sales person, or any sales person for that matter would tell anyone to wait. Sales reps do not know anything more than the general public knows. Given that, it's in their best interest to sell you a computer TODAY.

Not true. The week before the LCD iMac came out (and before the Time Canada leak), I had sales rep (higher up in the food chain) confirm that a new iMac was definitely coming out. They didn't say it, rather I asked them a pointed question, and as you know, body language makes up a good portion of communication. This person said one thing, but their body language conveyed the truth. Kind of like the old saying "Your lips say no, but your eyes say yes."
<strong>Your misinterpreting my reasoning. Dual processors are a whole different kinda party (FOABH talk). I will bet anyone on this board money that dual processor laptops in the same form factor they are in now will not appear in the next year or 2, if at all.</strong><hr></blockquote>
Craig, I'll bet you a postcard that the next Powerbook update will have dual processors.
If you win, i'll send you a postcard, If I win, You send me a postcard.
There have been rumors about dual processor PowerBooks for over a year. I would imagine that if there were prototypes, engineers must surely have been studying the ways to keep them cool; useable. Maybe, for what it's worth, they've unlocked the engineering secrets to making a dual-processor PowerBook not only a reality, but feasible.
Why? Motorola has historically had a lot of problems kicking out its high-end processors. Have they suddenly become competent? I don't think so.</strong><hr></blockquote>
Well appartently they didn't have any problem getting enough 7455's for Dual GHz machines off the fab's. Not to mention, enough left over for sonnet and newer tech, etc to start making upgrades....
DAMMIT! I can't WAIT till a suitible portable replacement for a desktop comes around!!!!!!!!!!!waiting for a new/substantial PB re-design is driving ME NUUUTTTTSSSSSSS! :eek: <img src="graemlins/bugeye.gif" border="0" alt="[Skeptical]" /> <img src="graemlins/surprised.gif" border="0" alt="[Surprised]" /> <img src="graemlins/embarrassed.gif" border="0" alt="[Embarrassed]" />
I find it funny that so many of you guys believe that we will actually see a dual PowerBook. The battery consumption would be enormous and the heat..OUCH!!!1 It is possible to have one processor turned off except when plugged into the wall, but seriously would this halfway defeat the point of having a dual. I mean if you can't use it on the go why put in into a laptop????? But then again you never know what apple will do...
\tLook for new powerbooks this month and new PowerMacs at MWSF.
First of all, if you look at the original "dual" post, the sales rep changed the topic to PowerMacs, and how the dual lineup was an attempt to make up for the slow G4 speeds.
But of course duals processor Powerbooks are possible, for many reasons. To begin with, cooling solutions are all over the place
Starting to wonder if Apple should stick with IBM for all it's chips. The G3 with SIMD unit, nice speeds and new bus for iMac and portables and the GPUL for the towers.
This PowerPC G3 is great! with 512k L2 cache and low power consumption design, it is the ultimate CPU for laptops! I hope Apple should use this new G3 chip for upcoming iBooks! IMO, the G3 chip is the perfect fit for the iBook market segment, the iBook users use it for writing reports, presentations, suffering internet and occasionally doing the presentations. With MacOS X.2, a G3 laptop is not slow, I have a ice-iBook 500/320 MB ram, the performance is acceptable while iCal is somehow sluggish, but the overall performance is good. If Apple do use this chip, whoa~ 512k L2 cache, it should retain all the advantages of the current iBook and push the performance to another new high!
Well, by the time, who's gonna buy G4 powerbook? Hmmmm.....by the way, the PIII/M is actually faster than P4/M in lots of tests except these apps. tinkered for sse2, this is just the bloody example of last generation CPU kicking the latest generation CPU's ass.
an old friend of mine has seen, touched and worked on a DP powerbook. he was told they'd be coming out a while ago, it never happened. dunno what ever happened with the whole deal.
as for why you'd want to do it, or how, i'm willing to bet that a processor running at 60% capacity produces less than half the heat of one running at 100% capacity. much like new projectors use multiple bulbs running at a fraction of their max wattage to get a brighter picture with less overall heat.

Not to mention we all get dual PBG4's.

i have a really hard time swallowing the fact that Moto is having problems kicking out 933Mhz and 1Ghz 7455's....</strong><hr></blockquote>

Dual postcards. kewl. ;D
\tLook for new powerbooks this month and new PowerMacs at MWSF.
i hereby predict that apple will not release
a dual cpu pb
instead........
they will release a quad pb
thats right 4 cpu's ...each cpu in one corner
with the top protuding out the bottom so it
acts as feet & heatsink....
any takers ?
But of course duals processor Powerbooks are possible, for many reasons. To begin with, cooling solutions are all over the place
I will send one out to the first person willing to take me up on the bet though...
(might as will have a little fun with AI)
done .... your on
ill take the postcard bet...
ai needs to liven up a little

Will Apple use it?? and surpass the Mhz clock of the PowerBooks??and the bus speed???

Awww man!! Give me a 1Ghz ibook with a 200mhz FSB please I am begging. I promise to buy one tomorrow apple!!!!!!

don't see why processors can't be the same way.
