IBM PPC 970MP A Reality?
The dual 64-bit core PowerPC970MP (970MP) is the next evolutionary step in the PowerPC 970 family of microprocessors. The higher frequency grade versions of the 970MP consume higher amounts of power than earlier IBM microprocessors do, and that can cause temperature issues. Each 970MP processor core contains a thermal diode used to monitor its operating temperature. The thermal diode must be monitored to ensure that the maximum operating temperature of the 970MP is not exceeded. These thermal diodes used by the microprocessors are unique to the PowerPC architecture and cannot be 'read' using standard thermal diode monitoring chips. This paper will discuss the characteristics of the diode and outline the struc-ture of a thermal diode monitoring circuit used to monitor the temperature of the microprocessors cores.

It's a little harder to hide this than the 970GX scandal.
Michiro was absent for a long time (months and months) and drops this on ARS Technica. :D
Edit: In case IBM sees the need to close the page. ;)

IBM confirms the PPC 970MP. IBM talks about cooling the monster and how the thermal diodes keep it from exceeding its maximum temperature. Which could also clue us in the dual core G5 Powerbooks and how it may cool itself down, when they do come out.

once again, i'm highly doubting the 970 will make it into powerbooks... it's still way to hot. they may use some technology from this but i am thinking you'll see dualcore G4's from freescale for awhile.. they are just much more better suited for laptops. ibook will get what the powerbook has and the powerbook will get dual core..
i've been wrong before.. but i'm doubting you'll see a G5 in a powerbook anytime soon.. also just realize that the Powerbooks were just updated.. after a year of being stagnant... glad i bought mine when those were just released last year.. woulda been a long wait! You might see ibm working on something like an actual laptop processor PPC though i wouldn't expect anything for at least another year. which is why i say we'll see dual-core G4's around january-february next year :)
I knew it! They're feeling the heat from Intel that says they're ready to ship dual core this month.

here's for hoping it's dual processor dual-core chips ;) THAT might make me buy one.. i won't be so willing to spring for a single dual core machine...
it isn't intel you gotta look out for anymore.. AMD is the one to look out for, their Athlon64 just totally rocks...
