Apple's newest CHUD 4.1.0 toolset includes an updated MONster.app. This updated version includes clues for a new Apple Quad G5 Power Mac, which would utilize two dual-core 970MP chips.
The above picture shows the older version of MONster.app on the left and the new version on the right. Note the added capability for up to 4 processors (or cores). Also, if one searches the new MONster application, one can find a reference to "970MP". Typing grep -binary 970MP MONster.app reveals:
Quad (dual dual-core) Power Macs (and Xserves) are coming. It's now just a matter of when. Hopefully they will be here by WWDC 2005.
The Processor pane in the Mac OS X System Preferences has also changed. With version 4.0.1 of the CHUD tools (top), the pane shows only the existing processors, and lists a "Clock Speed". With version 4.1.0 (bottom), the pane has changed to include 4 lines for (up to at least) 4 processor cores, and now lists a "Core Freq". (Note that the clock speed/core frequency is zero for my Cube, since its firstname.lastname@example.org GHz G4 7447A is not properly recognized.)
