Motorola

Thanks Mac coaster and 10 watts at a gig is amazing. ideal for portable stuff! unless they announce another version of this chip i just dont see it in the imacs or powermacs. I guess you could have duallies of this in a imac? going to be an interesting year for cpu's in the mac.

Oh, common a 750fx eats 5.7W at 900mhz according to IBM (well, one pdf said that, another listed a lower number for 800mhz, and somewhere out there I bet they made an estimate for 1000mhz). The power usage of a 7457 is completely unsurprising when viewed in that light.

the 750 is quite a bit smaller than the G4. 10watts at 1GHz is very low... the real question is whether this is max or average heat.

Motorola lists the typical heat on a 7455 at up to 35.5 watts.. I'm guessing this is at 1GHz. Their chart is total unorganized crap.
7455 product summary

According to that link.. I'd speculate that the 7457 uses 1/2 to 1/3 the power of a 7455. Not bad.
Too bad they don't give a crap about the Mac. the product and the press release are clearly marketed as embedded processors... not desktop processors.
If they gave 2 ****s about the Mac, they'd be pulling more power and pushing another 500MHz.

How did you continue to believe this for so long? Many people such as myself have shot down this silly idea time and time again on these very forums.

To be clear, I'm not saying I expected DDR FSB in these - I'm just asking if it was the 7457 that Moto said would be the first to have DDR a while back (when it was still just on the drawing board).

To be more generic - do any of you elec' engineers out there know why it is so hard for Moto to get DDR on the G4's FSB? If they have if for the Back side cache, then can't they use the same technology for the main bus?

I'm beginning to think that it's just that they don't care about it as imbeded app's rarely would need it.

I'm sure Moto could do a DDR FSB if they wanted, but their mainstream customers seem perfectly happy with the current SDR FSB. By sticking with their current FSB and only 2mb L3, the 7457 is pin-compatible with the 7455, which makes it very very easy for their customers to use. Drop-in replacement. Even Apple probably prefers the SDR FSB at this "late hour", since presumably the 970 will arrive and take over the high end, and then Apple can use it's DDR chipset unmodified for a long time in low-end stuff (where Moto belongs).

This was arguably the case with the 7455 as well.
 
Alpha samples of the MPC7457 and MPC7447 PowerPC processors are available today to selected customers. General market sampling is planned for March, with production expected to commence in Q4 2003.

Looks like the Cubes won't be getting any 7457 upgrade cards until around Christmas.

However the strangeness continues for Apple and Motorola...
 
Stick one of these babies in a 12" PowerBook, add FW 800 as a future investment, and I'm sold. :cool: It's GOT to help with the heat issues...
 
Moto is way behind, i guess they're just going to let IBM handle things as far as Mac from now on and concentrate on smaller applications for thier chips.
 
So is that fiscal or calendar fourth quarter I wonder??

Anway, that 7447 is heading straight for the iMac and 12" powerbook a.s.a.p
It's just what these machines need.. lacking a L3 cache, that size of the L2 makes a _huge_ difference, and of course the power consumption...

Getting 512Kb L2 cache in the iMac will make it a really good machine, not to mention getting that in the powermac will make a big difference too.

1.2Ghz iMac with a 7447 in it will make me buy (still fussing along on my PowerMac 450 :) - and Ill have got the money together by then.. ahhhh

Dang, now that you mention it, I guess it's not worth my time waiting to upgrade the ol' Quicksilver either. Stinking Moto.
 
When i read what moto has posted, it almost is as if they are saying we are anouncing the 970 will be going into the mac! Maybe this is just good news for us mac users because if they announced wider bus,ddr etc etc then we would say Oh this will be whats coming to the mac. Even if this was just a forerunner for a Mac G4 7457 that still means at least a year from now! Maybe this is GREAT NEWS!
 
I think I speak for 90% of us when I say whooooooooooooooooooooooooooooooooooooooooooooooo CARES!?!?

Wake up Moto. Sheesh, Apple is essentially using an embedded processor for it's "pro" stuff. I mean, if they can deliver 1-1.3 GHz at LOW temp, then yeah its good for the PowerBooks and iBooks. But man, when is the rest of the line gonna be up to snuff?
 
It's just a G4 revision (specifically, a die shrink). The target market is the same, most of the specs are the same, it's not that big a deal. Also, since the 7455 is listed as going to 1GHz, I would guess that the 7457 unofficially goes at LEAST as high as the 7455. I wouldn't be the least bit surprised to see it hit the 1.6GHz range, although I think the targetted 1.83GHz is a ways off still.

I still find it very interesting why all the mystery of how fast the new g4 and 7455 go. Why all the confusion when you look at current powermacs at 1.42 & 1.25 and then motorola says hey we got the fastest g4 it will be mass produced 4th qtr and will run at 1.3ghz HUH? Why the Mystery?
 
IBM may be doing better w/ lower wattage, but they aren't G4's. For the person who asked if it was fiscal or calendar, it's calendar. Whenever a company says that a product will be available in Quarter X, they are referring to the calendar quarter, as many companies use different schedules for their fiscal year (Ex: Apple: Oct-Sept; Microsoft: July-June).

An old, and pulled Motorola roadmap pdf said the 7457RM would have an on-die DDR memory controller. It actually didn't say anything about the 7457 bus. Everyone (correctly) guessed that this was proof that the 7457 would not support DDR... I held out that this only proved the 7457 would not have an integrated memory controller.

I was wrong :-(
 
The only thing Apple is missing is speed. I love my powerbook, but I've had pc's 2 years ago that were much faster. Stop overdoing all the optimization BS (Motorola) and move on with something faster already.

A Note on MOT

FYI, MOT is on their last leg. I work for a company that uses a lot of MOT stuff. They are currently quoting 20-week lead times, if at all. They have moved their manufacturing to Mexico and China and are having a lot of trouble with the manufacturing quality.

Based on this knowledge, I would have to believe there ain't a chance in hell Apple will be using anything made by MOT after conversion to the PPC970.

MOT is focusing all chips for the embedded market, which is much larger than Apple. MOT can no longer afford to support development for the 4% market share apple has. If you don't believe this look at MOT's stock price ($8.02).

Just MY $.02

Not really, they can go ahead and make the chips, heck they could release them before Moto because Moto sucks. Really if a much smaller company can make chips better and faster than yours for upgrading purposes that is just sad.

Moto you failed, last ditch effort will fail. You need to blow up.

side note: these will probably be used in all the computers not upgraded to the 970.

Really...
 
They're probably saying it's the fastest ever due to whatever benchmarks that they use which benefit from a larger L2 cache.

Still, lower power consumption is a good thing. It seems like the 12" PowerBooks don't last that long, with their more powerful CPU (compared to the iBook) and smaller battery (compared to the other PowerBooks).

Huh? I'm pretty confused about what you are saying, but in case you think otherwise, the upgrade makers use Moto chips (for G4's) and they are going to have to wait till Moto sells them 7457's before they can sell upgrade cards with 7457's on them.
