G4's in ibooks, when?

[Mr. Anderson]

I think the heat issue has done the rounds on the threads here before, I have to say that the TiPB is a good portable lap heater in a pinch. Although it won't be able to cook an egg (as some other machines have been said to do) the heat is not something to ignore. It also has a fan, that only comes on once in a while, even if I've had the machine running for hours.

The G3 running at 1 GHz vs. and 500 MHz G4 would be an interesting test. You'd have to make sure both machines had the same cache and bus, otherwise the comparison would made more difficult. I would like to see G3s and 1 GHz, maybe soon.

Does anyone know if the iBook even has a fan? To this day my iBook is completely silent in operation. It is the quietest computer I have ever used...even a little more then my iMac DV. All I have ever heard on it is the HD moving around in operation and I have done some things to warm it up pretty good...but never heard the buzz of a fan coming from it. The CRT makes a faint high pitch noise on the iMac...but that is all. I am guessing for silence it would probably be the cube and iBook tied with the slot loading iMacs right behind.

i've got 10.1 on my lombard and it runs pretty decent. i get hella pageouts but its not anything like trying to run windows in VPC

About the heat issue

I have a iBook 600 and fine it runs OSX just fine, but I do agree more speed would be nice. A lot of people on here have stated that because of "Megahertz myth" Apple would not have any problem coming out with a G4 iBook with around 500-600MHz. I agree a 500-600MHz G4 iBook would be quicker then the current 600Mhz G3 iBook, but I think if Apple is going to put a G4 in the machine they need to make it more powerful. I think they would also need a new case to handle the G4. Doesn't the G4 run warmer then the G3? What about power consumption?

I've wondered about Apple's laptop designs with respect to heat.

From everything that I see, the G4 produces much less heat (mhz for mhz) than a P3 or P4. And the G3 is better than a G4 in heat load.

Then why is it that there are so many heat issues with the TiBook and a G4 iBook? I think that if Dell can design a 1.6 Ghz P4 laptop that adequately handles the heat, then Apple could easily design an iBook with a 800 mhz G4. That shouldn't even be an issue.

They should also be able to stick in a 1.2 Ghz G4 (when available) into the TiBook with minimal fuss.

Anyways, just my 2 cents.

Dell might have a 1.6Ghz laptop, but have you seen that thing? It's damn ugly!

Of note, it's 1.7" thick, almost twice as thick as the tibook. That gives them quite a bit more space to deal with the heat from the processor.

There really isn't an issue with heat in the TiPB. It just gets a little warm, and the fan hardly comes on (only after the machine is running for hours straight), and then the fan runs for less than a minute before turning off. I'll find a thermometer and see how hot it gets when the fan goes on.

the problem is apple has much hhigher standards about what is a heat problem. pc lap tops have huge fans that run from the second you turn them on... and they are LOUD. the peecees also have huge vents and much much larger cases. and despite all of this teh heat on one of those things is much worse than any powerbook.

apple is trying to take a hot chip by their standards and cram it into a tiny case with no fan or vents. apple users are used to silient machines so any noise is annoying. so the fact that apple had to include a fan and that it runs sometimes annoys apple users. just much higher standards really.

Hot metal........

Well not quite, if you use the Ti Book on a desk (as opposed to your lap) then the Ti Book runs warm, but not uncomfortably hot!!! And the fan kicks in as dukestreet says...... just to keep stable temp and even then its only for a couple of minutes!!!

However when I'm doing serious DV and Post work, (Processor and Hardrive working continously!!) the Fan kicks in, and pretty much stays on, even then though, its no where near as distracting as the Power Macs......... and much much quieter than an equivilently spec'd PC laptop doing the same tasks!!

The Ti Book really is a marvel of engineering....... and the design of it certainly accounts for it running cooler than a PC laptop....... the case being metal, acts as a giant heatsink, particularly as the metal is thinner, the heat dissipates around the whole case more easily, also inside the Ti Book, there are metal channels, filled with highly conductive GEL that further dissipates heat from the Processor..... There are 4 fresh air vents that further act to keep the temp down..... The fan is the last resort that only kicks in as and when it is needed!! I think it's a truely superb peice of design and functional engineering!!

I think when they do fit the faster G4's if heat dissipation is a real problem, they may look at adding vents on the top of the machine, around the spot above the num lock key..... or even look at replacing the keyboard base with a vented or meshed version...... (heat rises!!) that would really reduce alot of the heat build up!!

Remember all the rumors of a backlit keyboard, Apple may go one further with the worlds first Heated Keyboard!!!

one suggestion for all these heat related discussions...

go to your local pc store and feel the heat from the pc laptops and imagine how hot they would feel if the case were metal (some models have metal casings)

the titanium case, as mentioned above, is a giant heat sink and that helps the processor further operate at optimal levels...the less heat in the processor, the faster it zooms
