Where is this coming from? After posting similar topic out into the public scrutiny that ensued I have learned that any sentance with the word G5 and laptop/notebook means unbearable heat and/or ridiculously large amount of cooling space (ie. tower).
But if somehow you have managed to make this managable please share with us, and with...APPLE!
Why in God's name would Apple want to use 2/4 440s?
The 440 is a "highly integrated processor", it features not only a CPU core, but also a DDR SDRAM Controller, PCI-X-bridge, DMA-Controller, Ethernet controller, and much more.
The processor core also features a 7-stage pipeline which tops out at 600MHz.
Nr9, while the 440 could potentially do well as a subnotebook (a very small one, that is)/minidevice, since it is a SOC-design (System on Chip), it would suck as a Powerbook chip. One reason:
- It is slow. -
You can very well be used in a computer, but it cannot be used in a high-performance product like the Powerbook is supposed to be.
If you want to make the 440 a high-performance product, you'd need to redesign a lot more than you want to. Why not process shrink the G5 instead, which is a proven, high-performance product today, which will be suitable for a Powerbook next year.
Sounds like a good start on an IBook if in fact a vector unit was added.
At some point I think Apple could set a trend in ultra low cost hardware by going high integration. While I truely doubt that the PowerBook is taking that route, it would certainly work for other potential Apple products. The IBook is a possibility if they keep it focused on its current market. As nice as the 440 series is though, currently it could not hope to be any more than a prototype for what Apple needs.
Thanks

I think that might Be a Little hot.

Ummmm.... a PPC 440 is not a G5
the L2 cache is only 2KB it is suitable for laptop.
Two: If it's 32-bit, what makes it equivalent to a G5, or better than, the G4 used in the current PowerBooks?

The Powerbook 440 would be a
1) Waste of time
2) Waste of money
3) Huge failure!

The processor core tops out at 700Mhz
at 700Mhz each core offer 2.8GFlop @ 1.5 Watt
it has a 440 core, a 440 FPU core, and an altivec core as one processor
each are pack into 2 processor chip. then there is a system controller controlling the two chip on one MCM module

G5 is not design for mobile computing
no matter how small you shrink it it wont work
11.2 gigaflop on DP floating point is not slow
