IBM and Motorola PPC Yields?

This is interesting and all... but I don't know what to make of this info.

Where would they get info on both IBM's and Motorola's yields?

I guess someone at Apple may know this information...

arn

and now we know why Motorola can't ever stick to their plans... and also know why they slipped on the manufacturing list to #11

Moto needs to die.

Cheers,

i hate moto!

I think this just shows how much better IBM is at manufacturing chips than Moto.

The fact they have higher yields means their manufacturing technique is better and more efficient than Moto. Higher yield would also mean they can sell cheaper, lower reject rate. This would explain why the 970 is not more expensive than the G4 (I'm sure I read that somewhere).

I agree with Arn, where did they get the specs? They did a good job with the G5, not great, but pretty good so who knows. Maybe they do have some good sources. It certainly would expalin why no PB updates recently. Sucks but explains a little.

The industry never wants to give out figures of their yields... that way they can have total price control... since they're the only ones to know their true yield... so this has to be B.S.

Right. And Apple wouldn't post the specs to the new G5's on their site a few days before they were officially announced.

You might be right that they are not publicly available, but these are rumor sites. Bits and pieces of information are gathered from unofficial sources and become stories like this.

I wouldn't be so quick to dismiss it for the reason given.

As far as I know moto doesnt have a 12" factory, and probably produces them on 8" wafers. No only that the die size of each chip is most likely different. (I suspect the die for the g5 chips is larger, but will get smaller over time.)

Unless these numbers have been factored so they are equivelent for those two issues you cant really compare them. I seriously doubt Moto and IBM share that info with each other.

However yeild rates for usable chips are very telling and are a good example of the work IBM has done with thier new 12" factory. It is day and night between the way IBM makes the chips and Moto makes the chips.

Also the story below that shows how long and how much Moto has been slowing Apple down for the last 4 years.
