New, improved G4 processor from Motorola

[takemehomegrandma]

A new improved version of the MPC7447 G4 processors sees the day of light, the MPC7447A, with some interesting features. The Register reports:
"Motorola's chip division - soon to be spun off as Freescale Semiconductor - today updated its G4-class PowerPC processor, the MPC7447, taking the part to 1.5GHz and paving the way for one more PowerBook G4 update the line before its upgraded to IBM's 90nm G5 chip, the 970FX.

The new Motorola part is dubbed the 7447A and adds on-the-fly clock frequency adjustment, allowing system makers to run at reduced frequencies according to workload. The upshot is longer battery life. And there's now a temperature-sensing diode included to monitor die temperature, Motorola says.

At 1.42GHz, the chip consumes 20W of power, Motorola claims, which compares well to the 7447's 21.3W at 1.33GHz. The company also mentions a lower power version of the 7447A that consumes less than 9.3W at 1.167GHz, which seems no better than the old 7447's claimed 7.5W at 1GHz. The low-power 7447A has a core voltage of 1.1V; the regular 7447A runs at 1.3V.

Essentially, the 7447A is a revised 7447, itself a low-power version of the 7457. The 130nm 7447 is currently used by Apple in its PowerBook G4. The iBook is based on the older 7455. The 7447 is a trimmed down version of the 7457, losing the latter's support for external L3 cache. The 7457 and both versions of the 7447 contain 512KB of on-die L2 cache. All three are fabbed using silicon on insulator technology.

According to Motorola, the 1.42GHz 7447A is shipping in sample quantities to "selected customers" for $245 a go, in batches of 10,000 CPUs. Volume production was not confirmed, but is likely to be reached during Q2 or Q3, we'd say."

Motorola once more doing the most minimal amount of work necessary to keep their stock reports sweet?

Sounds like tweaking to get a little more performance out.  Nothing exciting but even this has cost them well over a $million.

Motorola could do high performance devices if they wanted to but thats not their market.

Expect a big speed gain when they do a die shrink.

There are rumours they have a 2.5GHz CPU but it was put "on hold" and Apple went to IBM as a result.

One could try over clocking the new G4 for the potential high clock speed i.e. 1.6Ghz, 1.7Ghz, ‘etc’.

If Apple use these CPUs they'll have higher clock speeds, They get to use special "P" versions...

take a look at this.

Go Genesi, GO!

The purpose of extreme over-clocking is to see the potential of the said cores in relation to rumoured speeds.

Refer to http://www.theinquirer.net/?article=14245 as an example for bring rumours into practise (@retail's stage). (PS; this is not the first time i.e. A64/FX @~3.1Ghz point scorers in 3DMark community, but with non-air cooled solutions)

Does PegyII/A1-XE locks Memory/AGP/PCI clock speeds to 133Mhz/66Mhz/33Mhz respectively while increasing CPU’s FSB?

I wonder IF Moto’s PPC 7447A @1.6Ghz** vs IBM’s PPC 970 @1.6Ghz could spark price war similar to AMD vs Intel but at a minor scale i.e. due to products overlap.

**o/c at this time.
