IBM's 750VX Finalized?

That my understanding as well. As far as naming conventions go, how many different chips has Apple called G4? I remember when the G4 iBooks first came out no one was sure what model chip was really inside it.

Do people think they will call this chip a G4 as well? And, are we sure that these chips are even going to be in Mac's? IBM does sell chips to companies other than Apple.

All it could be is the current g3 with altivec. I'd not expect to many structural redesigns of the g3 processor, since if it was a completely new proc, it woudn' feature the same serial number.

Well, the G4 has long been criticized for the fact that it is crippled by it's FSB, which stands to increase to 400 MHz with this 750 VX chip. This is also the reason that DDR memory is virtually useless on a G4. Unfortunately, the memory is far faster than the FSB which pretty much negates the fast memory.

In essence, this isn't reverting to a G3. It's IBM producing a G4, which kicks the ass of a current Moto G4. The ONLY beef on the G3 was the fact that it didn't have Altivec. Pound for pound, it is a far better chip than the Moto G4. It runs cooler, uses less power, and as evidenced by the projections for the 750 VX, runs far faster than any G4 (scales to 1.8 GHZ).

As for 32 bit processing, that's all the G5 is doing currently (in practice). The only 64 bitness of the current G5's is memory capacity since both Panther, and all applications, run in 32 bit. Now I know this will change, but it merits attention that the current G5 is only running 32 bit stuff.

All said, great news. The 750 vx will be a great mobile and low end chip. Bye bye Moto, good riddance.

well it's just a rumor. it's hardly anything solid. we'll see in 9 months time whether this 750vx is for real or not.
 
I just decided to wait for the next ibook revision before buying a new one to replace my ibook600.

With a Q3 timeframe. I bet we see this in a Sept. 04 release. Making this 2 updates away.

I fear the next ibook revision will be a only a speed bump of the current chip. Not what I was really hoping for ....
 
Altivec or not, isn't that just a brand name of Moto?
IBM is mor ethan capable to produce avector processing unit that is compatible with"Altivec" instruction sets, and I don't think there are any legal problems either, afterall were they not all together in developing the PowerPC concepts in the first place?

may be someone else can shed some light on these "politics"?

Coem on with this procesor allready, these mobile intel chips are getting hot on the heals of our beloved powerbooks, we need to keep the edge here Apple!
 
If this isn't being released till much later in 2004 you have to wonder what Apple is going to do with the current processors?

I havn't heard anything from moto as to what they are doing next with the G4 and it seems apple would be willing to put all processors from IBM into their machines.

If thats the case why the wait?

Get them in the machines NOW!

400mhz DDR bus might sound good now but what use is this in a years time? What will Intel put out in 12 months?

We all know for a fact laptops will be nearing 4Ghz on the windows side and PowerBooks will be on 2? Woopie doo!

<sarcasim>Wow! I cannot wait.</sarcasim>
 
IBM did it already

the G5 has an altivec-like vector-processing unit... let's call it "velocity engine" as Apple like to call it...
 
yes but no

in low end PC labtop you will find 3-4GHz P4 by end of 2004, yes, but it is crap, even PC users recognize it. the real compettor for Apple is the Pentium M, which is at the moment at 1.6GHz....
a 4GHz P4 in a labtop does run at 4GHz...it is a fact, check on PC web sites, it is just a argument for marketing... for no brain users.
Just look at the price of a labtop with a 3GHz P4 and a labtop with a 1.4 or 1.6 GHz Pentium M, you will see the latter behind the most expensive...
 
Altivec, VMX, Velocity Engine, all the same damn thing...

IBM & Motorola jointly worked on the instruction set known most popularly as Altivec. Altivec however is a Motorola trademark, which is why Apple doesn't uses it (and uses Velocity Engine instead). The original name was VMX. There are politics to IBM calling it's SIMD engine Altivec because that is a Motorola trademark. There are no politics to IBM having a VMX SIMD engine, because they have rights to such a thing. However until now they didn't see a big reason/market in making chips with VMX and competing with Motorola. With Motorola's chip foundry falling apart and being spun off, there is reason for IBM to produce such chips, if only because Apple promises to foot part of the research bill.

It will most likely be dubbed as a G4, as it wouldn't be as powerful as a G5, and Apple wouldn't want to reintroduce the name G3.

Maybe the new chip should be called the G4 Extreme, since Apple seems to like that word (Airport Extreme, Quartz Extreme, etc.). It would sound faster than the current G4s but won't steal the G5's speed connotations.

The fastest Intel laptop chip is at 1.7 GHZ (at least it was afew weeks ago, haven't checked if they speed bumped lately).

The Intel Pentium M is a far superior mobile chip than the P4 you are referencing.

edit: Eric beat me to it.
 
If this ends up in the iBook then we could look at something like this:
lowend 1.6
mid range 1.8
topend 2.0

or

lowend 1.5
mid range 1.6
topend 1.8

This alone makes me think the PB's #'s would be abit higher as most folks don't look at the processor they only normally look at it's clock speed.

Is the 750 VX 64 bit? I would hope so, so Apple can introduce it's 64 bit OS sooner.

The 750 GX currently at 1.1 from IBM.

Assuming Apple uses this chip, this statement is a bit of a no brainer, of course it would end up in an iBook eventually, if not to begin with.

And all 4GHz machine will weigh a ton compared to a iBook or PowerBook not to mention you will need to have it plugged in almost always because the P4 eats batteries for breakfast.

Most folks I know are getting Pentium M's which run alot cooler and run alot longer on battery power.

The only use for P4 now is in gaming laptops but once a laptop goes over 5lbs I don't consider it a laptop anymore.

Don't get me wrong, i don't disagree but people will look at the numbers... battery life and true performance will take a back seat on the otherhand.

What are your thoughts on third party hardware developers using this chip to make processor upgrades? I'd like to see a 2Ghz G4 processor upgrade card for my old G4 PowerMac. This chip looks like a great candidate for such use also.

That's a miss-conception... just as the belief that the G3 is a next-gen 603 and the G4 is a next gen 604 is a miss-conception. I think the truth is a little more in between these two and yet not all there.

They are similar (G3s and G4s) because they are evolutions of the PPC development, but the G4 isn't just a G3 with altivec. They had different pipeline lengths, the G4 had better FP performance... Since then, the designs have each continued to evolve. There were changes to FP and altivec in the G4 when it was reved to the 745x series.

It isn't fair to say G3 + Altivec = G4 so this new G3 is just a G4.

How about we go with 'this new G3 is somewhat congruent to a G4!!'

:)
 
Well battery life is important. I have an IBM with a 1.6gh p4M. The computer is as powerful as the new pb, and as damn expensive. But the battery life sucks, its terrible. It doesnt last more than an hour and 15 minutes at the most. And a extra battery is over $200. (and I didnt buy this, i got a grant for it, lol). But this fact alone makes it almost useless for anything more than to sit on a desk.

Im still waiting on a full featured 12' pb. Backlite keyboard, 64mb graphics, same processor, etc. Apple make one and it would be my next computer!

Don't wait... leave the Mac and buy one. You might get lucky and burn your bits off in the process.

Intel has publicly stated that it will not try to push performance in the mobile space by pushing clock speed. The Prescott will produce over 100 watts at around 3GHz. You want a variation of that, only faster in a laptop? good luck.

The Pentium-M is the first post P4 attempt by Intel to make good on its promise to make more efficient processors.
It is entirely possible that you WON'T see PC mobile processors increase much in clock speed for a while.

<sarcasm>
Insiteful post though..
</sarcasm>

sorry, had to borrow from you a bit ;-)

Dang, I sure thought my brand-new 15 inch AluBook was a laptop. Shucks, neither is the 17 incher nor the 14 inch iBook. That sucks.

I would consider a laptop that resembles a college textbook more than a notebook to be not a laptop. My friend with his 1.7 inch thick Windows POS registering 447MB of RAM? said that he likes that his computer is big and heavy and loud because that way he knows 'that there are parts in there'

Windows users sure seem to have a skewed view of the world...
