IBM Officially Unveils Dual-core PowerPC Chips
PM4RK5 writes "Today at the Power Everywhere Forum in Japan, IBM officially unveiled its rumored dual-core PowerPC line of chips, the 970MP. Code-named Antares, these chips have been rumored to be under development since 2004. It is believed that Apple has been working with prototypes and is likely to use them in forthcoming updates to the PowerMac G5 line. The press release is in Japanese; as of this writing, IBM has not released an English version. Some of the slides from the presentation given by IBM are available.
The processors pack some impressive specs, ranging from 1.4 to 2.5 GHz and including 1MB L2 cache per core; the chips also include the ability to power down the extra core when it is not needed. Alongside the 970MP, IBM also announced its low-power 970FX chips, ranging from 1.2 to 1.6 GHz, with power consumption ranging from 13 to 16 Watts, respectively."
Apple (Steve-boy) already mentioned that there were moreproc. updates coming, and even said there were some good updates coming down the pipeline. His big concern was not just "now" but the future road map.
Best performance per watt != Lowest power usage of highest-performing part.
The Pentium M family is much lower power than the Pentium 4, and has reasonably good performance. I don't think AMD really has a chip that competes with the Pentium M, even though AMD's chips are generally less power-hungry than a Pentium 4.
