The Gobi isn't even out yet and you're asking about the Mojave.Originally posted by macphoria
What would you rather like to see happen? Motorola's G4 or IBM's AltiVec/SIMD enabled G3 (which is virtually a G4) in the next iBook? Which would be better?
This was somewhere on MacRumors articles.Incidentally, is the Mojave the chip that's supposed to have Altivec on it?
Seeing as how the Mojave won't be available until sometime next year (source: macphoria's post above), it seems like the iBook will either get a G4 or stagnate at 900mhz for another 6 months to a year. So my vote would be the 7447 G4.Originally posted by Daveman Deluxe
I would rather have the SIMD/AltiVec G3 in the iBook. It uses less power and produces less heat than the G4 and it runs faster. Hell, the current G3 design runs faster than a G4 of the same clock speed unless vectors or complex FPU instructions are involved.
Which one is this?Originally posted by yzedf
G3 - 750HX (up to 1100MHz and 200MHz bus)

My bad. 750GX.Originally posted by ftaok

Yeah, I was replying to the guy's original question of whether they should go with a G4 or Mojave in the iBook. The Gobi wasn't part of the question.Originally posted by yzedf

What I meant by that statement is that Apple could discontinue the iBook and replace it with a low-end PowerBook. Basically, the 12" Powerbook is more like a G4 iBook than a scaled-down version of the 15" TiBook or 17" AlBook.Originally posted by MacBoyX
What on earth would make you think this? iBooks sell like hotcakes. I mean how many School Districts in the US have bought one for EVERY Student in a certain grade or even grades.
The iBook is NOT going to be discontinued. Not to mention the number of NON educational users who buy them.
I for one would like to see Apple drop the G4 all together and keep with IBM and the G3 which keeps getting better and faster first GOBI them MOJAVE.

About your point of dropping the G4 in favor of IBM's G3. That's not gonna happen unless IBM gets Altivec into the G3. Apple want's chips that have Altivec. IBM only licensed Altivec from Moto because their customer (Apple) requested them to do so. If the Mojave does come out with Altivec, I suspect that Apple will use it. But a Mojave with Altivec is no longer a G3. It becomes a G4 in essence.
I don't think Apple will use the Gobi since the 7457/47 will beat it to market. Plus, the 7457 will be available at higher clock rates and will run pretty cool. After the 7457 runs out of steam, Apple will either use A) the next Moto G4 (or better) chip, B) the IBM Mojave (provided Altivec is included), or C) a low-powered 970. The Gobi will probably never find it's way into a Mac.

A low 1.x GHz chip with Altivec @ .13 micron SOI and 4 pipeline stages seems about right (although before I compared it to other chips it seemed much too high). Moto's gotten 1.43GHz @ .18 micron SOI and 7 stages. Intel hit 1.4 GHz with 10 stages @ .13 micron non-SOI. AMD used 14 stages @ .18 micron non-SOI (iirc), and got up to something like 1.8GHz (I can't remember when TBred was introduced).

well, motorola kinda screwed itself on that "viable" part... i hope they get their act together too. competition for apple's business might be nice. but one thing to consider is that Dell gets a lot of discounts on intel stuff because they agree to ONLY ship intel chips on their hardware. i dunno if there would be a dynamic like this in the PPC market, but it's possible. if motorola gets shut out by apple, they will still have market for their processors. so there will always be potential competition on the PPC side, i suppose, whether apple drops moto or not. and dropping them for an exclusive contract with IBM might be better for apple.Originally posted by snoopy
However, I would like to see two viable suppliers of PPC processors, not just one.
There's something that I didn't need to hear.Originally posted by hvfsl
I think they should use the G3 with SIMD. This is because the G3 is cheaper than the G4 and the G3 is the same speed as the G4 in most things except when AltiVec is enabled. The G4 is would actually be the same speed as a pentium3 at the same megahertz if it was not for AltiVec.

OK, I stand corrected. It's just a little strange that IBM is calling it Altivec.Originally posted by snoopy
IBM did not have to license AltiVec from Motorola. The US patents for the AltiVec SIMD engine are held by IBM, Motorola and Apple. IBM implemented their own version of this SIMD engine in the 970, and Apple has always called it the Velocity Engine. IBM publicly stated they are a co-developer and have a right to this technology. However, I think Motorola has a copyright on the AltiVec name.
Motorola's 7457 is quite real. It's slated for release in Q3 2003, which means anytime between July and September. Whether Apple will use them or not is the question.Originally posted by Ensoniq
People keep talking about the PPC 7457 from Motorola as if there is actually some chance it's going to come out. Is there any real evidence that it's close to being manufactured and shipping?
For all we know, IBM's Mojave G3+SIMD is closer to completion. The recent 750GX info doesn't discount that the 750VX may be around the corner too, in a surprise blow to Motorola by Apple.
