PPC 970 Confirmed for Apple?
batboy78 writes "In what perhaps is the first 'official' confirmation that IBM's PowerPC 970's will be used by Apple, BusinessWeek claims that IBM has confirmed that it's developing a new set of chips for the Mac: 'IBM says the new Apple chip will be of the 64-bit variety, which means it can process twice as much information per cycle as existing 32-bit chips.'" CT The article has been updated to make the confirmation seem... well, far less comfirming.
Apple sales guys must hate this kind of press.
">>>IBM says the new Apple chip will be of the 64-bit variety, which means it can process twice as much information per cycle as existing 32-bit chips.
"Argh! Head... going... to... explode..."
He didn't say twice as fast... he said that it could process twice as much information per clock cycle... he is correct with that statement.
Did I miss the part of the article where it said that IBM confirmed making PPC chips for Apple? I don't see a press release or any other real evidence. This is just an article about some guys speculation as to what is happening.
The G4 is a 32-bit CPU with a 128-bit vector processing unit (aka SIMD Unit) called Velocity Engine or Altivec. This kind of like (though much superior) to MMX, 3DNow!, etc. The new IBM chip is suppose to be a 64-bit chip with a 128-bit Altivec compatible unit. In the past, the Altivec unit has always suffered from Motorola's slow FSB on the G4. One bonus of the PPC 970 is that it sports a 900MHz DDR bus that can keep the SIMD unit fully fed.
From the article:
Although Apple won't talk about it, IBM is developing a new set of chips that Apple will likely use to replace theaging Motorola processors used in its G4 line.
How is this "official confirmation"?
The past has shown this to be untrue. Apple held the CPU speed crown with the G3s when they first came out. Motorola has been screwing Apple for dropping the clones (and cost Moto big $$$), and because there is no incentive in their embedded market for fast FSB. Mark my words! This is just the beginning. IBM has the most advance fabs in the world. And they just made a deal with AMD to share process techniques. The POWER 5 (and its PPC 980 derivitive) are a hell of a lot closer then you think. Oh, you want benchmarks? http://www.macbidouille.com/niouzcontenu.php?date= 2003-05-05#5440
Altivec or Velocity Engine was developed by Apple, IBM and Motorola together (AIM), so Velocity Engine and Altivec are the same thing. The name Altivec is owned by Motorola, but the actual 128-bit vector processing unit is owned by AIM, so IBM can use it in their processors, they just can't call it Altivec.
No, no, son, the standard is "on the head of a pin", not "in a Volkswagen"! :)

Volkswagens are units of measurements for sizes of asteroids that are about to impact Earth.
Other measurements in this system:
% of the width of a human hair
Length of a football field
Length of an Olympic-sized swimming pool
Equivalent # of bowls to 1 bowl of Colon Blow (or Super Colon Blow) cereal
And you thought _metric_ was cool...
Actually, this is wrong. A 64-bit process cannot necessarily process 2-32-bit instructions at once. The number of parallel instructions a processor can process is entirely dependent on the number of pipelines it has. A 64-bit processor with 3 integer pipelines can process 3 32-bit or 3 64-bit integer operations per cycle (in theory) while a 32-bit processor with 3 integer pipelines can still process 3 32-bit integer operations per cycle.
A deep unwavering belief is a sure sign you're missing something...
I was more intrigued by the "1.8 GHZ per second" claim.
1.8 Billion instructions per second per second. It's about time that somebody made an accelerating chip - way to go, IBM!

Jeez... did any one read the article? it is just repeating the rumor. It does NOT say that IBM is confiming its making the chip for macs. go back to work and clean the jism off your screen.
Some drink at the fountain of knowledge. Others just gargle.
The G4 really was a supercomputer at launch... but only by the letter of the law. The G4, capable of over 1GFlop, came in north of the Federal definition of a Supercomputer (in relation to the export of arms). So.. you couldn't ship the Macs to any 'enemy' country like Libya... or even to France... at least not right after they were released.
;-) A dual 2.5 GHz machine would be capable of up to 40GFlops (max theoretical) by Apple's calculations. ;-) hehe.
The US Govt. quickly revised the rules. I believe supercomputers are just north of 50GFlops now.... so Apple could get real close again with an SMP 970... if you go by Altivec performance again.
I'm not feeling witty so bite me
Since when did a BusinessWeek article become official confirmation? Probably, BusinessWeek got their information from rumor posts on MacRumors.com. As well as calling it "official" instead of just official, MacRumors also adds:
No specific executives are quoted, however... so it's unclear from where the information originated.
The PowerPC 970 has been widely rumored and expected to be used in Apple's upcoming Macs, though both IBM and Apple had not made any official announcements about their use.
From the article:
"IBM did not confirm it was building a chip specifically for Apple, but it does say its new PowerPC chip will work on Apple platforms."
So IBM has confirmed that the new chip will work in Apple Machines, something they heretofore had not said.
