Knucklehead! The P4 Celeron is a P4 with half or quarter the level 2 cache (depends on the P4 being compared) no HT and a slower FSB. The architecture could not be more different than the PII. Where did you get such nonsense from?

Wow, my chin hit the floor when I typed "macrumors.com" this afternoon. I still can't believe it. Forget everything, jesus.. g5 powerbook is coming.
This is going to drive prices on things like (Powerbook g5's Lombard) into the ground... wow, this is freaking amazing.

I'd also go for the PowerBook. You can take the 1 GHz model, and customize it to have a SuperDrive, and that will bring the total up to $2199, so that would be an $800, instead of $1100 if you went for the 1.25 GHz model. Plus you get some great additions for the PB line such as FW 800, more video memory, and up to 2 GB of RAM, whereas the iBook maxes out at 640 MB.
Yes, I've got one already (900MHz). Just keep it it runs fine and in several years you can still play with OS 9!
Yeah, maybe next summer.
You can have the consumer and pro product lines on the same processor. Apple did it with the Pismo and original iBook, with the iMac and Power Mac G3, with the iMac and Power Mac G4, and now with the iBook and PowerBook G4. One day all lines will be on the G5 or the G6 as well.
It is very important that you understand this.
Your problem is you are talking 5200 Ultra, but the PB has the 5200GO.
Difference? The 5200Go has half the memory bandwidth (64 bit) and lacks any hidden surface removal technology (z-buffer culling). It is also much, MUCH slower clocked (GPU and RAM).
The memory difference should effectively half the performance (everything else being equal) and the HSR absence means the 5200 is effectively useless for games.
A 5200 desktop card with 64bit memory on a 3.3GHz P4 gets 4600 3dmark points. The same machine with a 8500/9000 gets 9000-12000.
It is possible that this is a 64bit 9200. Such parts existed when the M7 and M9 came out but they were largely derided by the review sites - why include discreet video only to cripple it? My guess is that this 9200 will use a 128 bit memory bus.
The 9200 absolutely decimates the NVidia part. ATI have owned mobile performance since the M7.
You are right, this is a RV280 derived part. The 9200 is a M9/9000 with AGP8x support and a new packaging called flex fit - this may mean upgradability in the future. But not directly from Apple.
Neat features that hopefully will be supported in OS X:

Where do people get these strange ideas? The two-tone color scheme is the same as on the 2.3 iBooks (the ones with the 900Mhz COMBO).
The only changes in appearance is the Slot-loading drive.
You can't really see the keyboard on the high-res pictures on Apples site, so I can't tell if this has changed. I doubt it. But if you have alternative pictures, please show us.
The L2 cache speed was 1:1 since the 550/667 Powerbooks (link). Which corresponds to 7455 (and maybe the 7450). In other words, the only indication that these might be 7447 would be the long battery life, longer than the last Ti-books having the same battery capacity. On the other hand the size of the L2 cache would point to an 7445.
Actually, 128k L2 cache, but otherwise correct. Though the 400 Mhz bus is deceptive in that most systems only come with DD266 memory anyway, so it is effectively 133 Mhz double data rate (266 Mhz effective bandwidth), much like Apple's DDR266 memory spec on the iBook is deceptive because the FSB is only 133 Mhz single data rate (133 Mhz effective bandwidth).
Re: Re: Re: hmmm
L2 cache is on the chip itself. It is VERY rare for a chip to change how much L2 cache it ships with without an overall relayout of the chip.
IMHO, it is quite unlikely that this is the Moto 7447 chip with less L2 cache than the rest, and it is also fairly unlikely that this is some unreleased IBM chip (750GX). If I were told this isn't the 7445 chip from Moto, I'd definitely lean towards the 750GX possibility over an L2-deprived 7447 from Moto.
Personally, I am more thinking that this is still a 7445 and that the battery life was increased through other means (maybe that 1/3rd extra pound is battery ...)

Very unlikely. There are too many G3's out there in use for a new version of OS X to require a G4 or better by next year.
However, yes, I can imagine in 3-5 years the G3 will be phased out of support and THEN the next version of OS X (Alley Cat ... or was that Tabby?) will require Altivec.
Is there any type of hack that can work around this? I heard that iDVD will only work on a G4 with an internal Superdrive, not an external Firewire DVD-R, but I wanted to know if there was a workaround. Although you PowerBook owners say "way to go Apple!" because they've purposefully crippled the iBook, there is no technical reason why they couldn't allow iDVD to run on the iBook now that it has Altivec. What a lame move to cripple your computer system on purpose.Originally posted by johnnyjibbs
And if you want to use iDVD you still need a PowerBook. Way to go Apple!
Also, I heard a rumor that these new iBooks are actually using the IBM 750GX/FX processor which is a G3 + Altivec. Anyone know if this is true? If so, I'd love to see benchmarks because it might perform better clock-for-clock than a Motorola G4. The battery life would be much better too because the G3 is such a good mobile processor.

jettredmont:
Thanks for setting me straight.
Also, Steve might have just found a new way to spoof battery life.
"They don't need to know the chip was under-clocked to 400mhz and has the screen completely dimmed and set to 640*480 "

I can just imagine Windoze users coming to apple.com to download iTunes and be intrigued (sp?) by apple's lower priced products on the home-page.
I think this was all timed very sharply. Very sharp indeed.

Literally, with a Motorola 7455. Apple is pleased to announce the new G4 iBook easy bake oven. Move over ti Books, make way for the new hotpad.
I reckon these new iBooks do have alti-vec, hence the G4 name. G4s have alti-vec. But Apple probably isn't making a big deal about this any more because of potential confusion with the G5.
The G4 apparently has a 128-bit core (the "Velocity engine') and the blurb always mentioned how this was better than "32-bit chips found in traditional computers". So despite the G4 being a 32-bit chip, it looks like it's actually 128-bit. But this could be confusing for consumers and conflict with the 64-bit marketing of the G5 ("worlds first 64-bit computer"). Hence, the need to drop this text from the G4 pages.

suggestion
well guys i just read 7 pages of arguments about the comparison of the ibook to the powerbook.... what about the ibook vs dell laptops or gateway , etc.

Is the 12" fast enough
I am very close to buying the 12" Ibook...but I amconcerned about speed. All we will use it for is to surf the internet and send and read email..maybe store some photos.
Is the 12" fast enough and do I need to upgrade it a bit?
thanks

max memory?
The tech specs say:
Processor and memory
* 800MHz, 933MHz or 1GHz PowerPC G4 processor with 256K on-chip level 2 cache running at full processor speed
* 133 MHZ system bus
* One of the following memory configurations:
o 256MB of SDRAM (128MB built in and 128MB in SO-DIMM slot)
o 384MB of SDRAM (128MB built in and 256MB in SO-DIMM slot)
o 640MB of SDRAM (128MB built in and 512MB in SO-DIMM slot)
* One open SO-DIMM slot; support for up to 1.25GB
What is the meaning of that last line, the open SO-DIMMM with support for up to 1.25 GB?

While I agree with most of your other points, I just don't get why you wouldn't want the PB to go G5, it makes no sense at all other than buyer remorse on a recently purchased product.
