I hate to break it to you, but according to IBM.com, the Sahara uses 256 bit pathways.Yes, the G4 IS that much better than the G3. the G3 doesnt have the 128 bit pathways
WRONG. WRONG. Damn know what your talking about before your open your mouth. The new G3's used in the Ibook are made by IBM. They are IBM's brand new chips they are not slow. They run on a .13 Micron process(while the G4 uses .18) they only have 4 pipeline stages(while the G4 has 7) they can run at close to the same clockspeeds(although the G4 will probably get faster at MWNY), the g3 has 512k of L2 cach(while the G4's only have 256k), they Use SOI(silicon on Insulator)(so do the G4's), they can run on 200Mhz Buses(ibooks dont)(the current G4s only support 133 as far as i know hopefully this will be changed at MWNY). Heck as it stands from what ive seen these G3's are a good deal faster than the current G4's clock for clock. The only reason that the G4 is faster in ANYTHING is because of Altavic. BTW no hard feelings im not trying to spite you just wanted to point out that you were incorrect. Yes the OLD G3s(from the Blue and white era) were slower than G4s clock for clock but not the new ones.Originally posted by G5orbust
Yes, the G4 IS that much better than the G3. the G3 doesnt have the 128 bit pathways or the Altivec. Also, the G3 is on a higher µ process (µ = micron). The G3 is on the ibook for one reason, tehy want a budget notebook. If Apple didnt, there wouldnt even be a G3 ibook. There would just be a lower powered powerbook instead.
Please elaborate. Isn't context switch performance related? Wouldn't the systems being compared have similar context switch performance? I'm not a CS student, as you can tell.Originally posted by Catfish_Man
2) Integer performance has very little effect on multitasking. Context switch performance does.
5) I would say that what you noticed with the iMac/TiBook comparison is the slow laptop hard drive. Try comparing to a PowerMac at that speed.

Why can't IBM just buy Motorola's semiconductor business and merge the two chip designs? God I'd love that (even though it might be impossible)
Ain't it the truth? God has been smiting us Mac fans for years now.Because that would make us all happy, and the gods wouldn't allow it.
That's a bit over the top, you can't possibly compare the new 700Mhz G3 (or any for that matter) with that piece of sh*t CPU from intel!Originally posted by cb911
you might as well save yourself some money and just get a Celeron...
Maybe, but your comparing the celeron, a PIII/P4 maybe I could understand, but the celeron is total crap and would get it's a$$ kicked by the G3.Originally posted by cb911
i don't know...
intel have some pretty zippy processors. and ddr ram...
the G4 is still king, but we're talking about G3s here.
I would totally agree. My iBook 600 with the G3 750cx kicks the **** out of any Celeron and I would imagine the new iBooks with the G3 750fx "Sahara" run faster. Up to 35% faster then the last generation of G3's according to Apple.Originally posted by verbose101

Everybody keeps saying how these Saharas are so cheap. But no one ever quotes prices (including IBM). Does anyone know what they cost?Originally posted by Abercrombieboy
For a laptop like the iBook the G3 makes a lot of sense. I like the minimal power intake of the chip. I wonder what would happen to battery life if Apple went to the G4 in the iBook and didn't do anything with the battery? It also is cheap to buy, is stable, runs programs well and can hold it's own or take out any other budget processor out there. The fact is, in consumer laptop market segments Apple is much more competitive for speed then they are in the professional area.
Yes the G4's going to kick the crap out of IBM new G3's in Photoshop, but thats because its altavic optimized, try turning of altavic on your G4 and then do a comparison. Not to mention that if you have a new tibook you have a much better vid card than ANY Ibook as well as a faster Front side bus. Anyway the issue is that outside of major Graphics apps(photoshop, FCP, Maya(i think), ect) Altavic is not used as much as it should be. And without altavic id bet IBM's new G3s are a good deal faster than the current crop of G4s clock for clcok.Originally posted by cb911
the G4 is heaps better then the G3. most of the people in my class have iBooks and i really feel sorry for them. PhotoShop and other graphics apps run so much faster on a G4. one of them has 300 and something MB RAM and i only have 256 MB in my TiBook and it is still heaps better.
the simple truth is that G4s are the ruler(at the moment).
don't get a G3. you might as well save yourself some money and just get a Celeron...
...and if you turn off the FPU on a G3 then it's slower than a 604! Wow! I want a 604! Bah...Originally posted by Malus120

The emac can still be used for the things that really require altivec...Originally posted by ftaok
NOTE - it is curious to note that the eMac has a G4 in it even though it doesn't have a SuperDrive option. Makes me wonder why Apple even bothered with putting in a G4 when the Sahara seems like a much better option for the eMac.
Good point, SPG. I always seem to forget about FCP when I talk about stuff like this (and at $1000, who can blame me for forgetting?). Seriously, I guess I'm misguided, but when I think of the eMac, I think of a computer lab for 3rd and 4th graders. Not really the core type users of FCP.Originally posted by SPG

Photoshop-screen's big enough to learn it, remember this is an Educational Mac
FCP-it's got firewire. And if any of you remember the good old days when monitors were expensive, many of us would edit on 17" monitors and consider them adequate.
DVD Studio Pro -they have external firewire DVD burners. A lab full of emacs could all share one or two burners to keep costs down.
The G3 is slow on FCP renders, real slow, and damn near impossible for MPEG2 transcoding for DVD. If you plan on doing any video/DVD stuff the G3 is out of the question...too bad though, I think the iBook is a great machine and I would buy one in a heartbeat if it had a G4.
