Look, I'm not an Apple engineer so I honestly I can't validate what I wrote.......but I'd also like to think I'm not speaking out of my ass. I can tell you that I have read quite a few articles on-line concerning the PB's, and cooling challenges Apple is going to have with the G5's. Perhaps my information is dated....perhaps it was simply bad. If I can "dig up" any of these articles I'll gladly share them on this board.
Still looking for some of those articles. Here is one from
www.lowendmacs.com.
One more thing. I have no desire to "piss people off" nor do I want them to "think I'm an idiot". I have been "reading the other posts before mine" on this board and 2 or 3 others. As a matter of fact I've read hundreds of posts up here over the past few weeks. I can't say I've read them all, after all........I do have a life. The response from "Zync" to my initial statement is was arrogant, especially considering this is a RUMOR board. Not one of you up here is an Apple engineer nor can any of you can claim you know exactly what's going on with the PB's. You people need a life. Geez.... I've seen more bull**** spread around up here in the past few weeks than on any other board, and then you jump my ass for making reference to the article below.
Go stick your heads in the sand!
From
www.lowendmac.com:
On the heat issue, Smith notes that Motorola claims the new chip consumes 16.6W at 1.3 GHz, compared to the current 7455's 15W at 1_GHz, so it will certainly not improve the heat issue. For comparison, a G3 750fx chip running at 800 MHz draws only 3.6 watts, or a projected 5 watts at 1_GHz (not yet marketed), which is one reason why I contend that the G3 is still the best PowerPC chip for laptops if you don't need the AltiVec horsepower of the G4.
IBM is said to be working an a G3-class processor with AltiVec, but it remains to be seen whether it will offer any power economy advantages over the Motorola chips.
However, the G5 processor used in the new Power Mac towers introduced this week consumes a whopping 42W at 1.8 GHz, making those machines' elaborate nine-fan computer-regulated cooling systems obligatory, and their resemblance to portable space heaters is more than a whimsical observation.
On the basis of that level of power-sucking and heat generation, I would suggest that G5-based laptops are an extremely unlikely prospect any time in the foreseeable future.
Tony Smith contends that the 7457 remains the most likely processor candidate for the 15.4" PowerBooks expected to be rolled out later this summer.
