Think Secret sheds some light on an upcoming processor revision to the 970 line dubbed the AntaresSP, or PowerPC 970GX. This single-core variant of the 970MP will initially come in at speeds around 3GHz and is said to feature 1MB of L2 cache, double what the 970FX processor sports. Like the 970FX, however, the processor will not have any L3 cache. Availability hints are in the early part of 2005. Availability of the 970MP (multiple core version) is not yet known.

Additionally, a low-power-consumption version of the PowerPC 970 is expected to emerge for use in the upcoming PowerBook G5. The chips are expected in 1.6 & 1.8 Ghz variants, although not much more is known. The article goes on to say that if the 970GX is not ready for a PowerBook G5 introduction, that model may receive the low watt, high output previously rumored PowerPC 7448 G4.
