’s link picked up the exact rumor threads people were chasing in March 2005: CHUD/utility strings hinted at a PowerPC “970MP” part and several outlets treated that as evidence IBM was working on a dual‑core G5. (theregister.com)

Short version of the jargon: a “dual‑core” chip contains two CPU cores on one package; “dual dual‑core” usually means two physical processors, each with two cores — four usable cores total. The Darwin/XNU kernel in Mac OS X already supported symmetric multiprocessing, so the OS could schedule threads across multiple cores; real gains require applications that actually do parallel work. (en.wikipedia.org)

What actually followed: Apple publicly announced the Intel transition on June 6, 2005, while IBM’s dual‑core PowerPC 970MP was documented around July 2005. Apple shipped Power Mac G5 models that included two dual‑core G5s (the Power Mac G5 Quad) on October 19, 2005, and then introduced the Intel‑based Mac Pro (two dual‑core Xeon CPUs) on August 7, 2006. Those press announcements show the sequence (rumor → IBM dual‑core → G5 Quad release → Intel Mac Pro). (apple.com)

Tie‑back to the thread: ’s excitement about hardware was justified and the software concern was valid — apps must be multithreaded (or updated by their vendors) to use multiple cores. Apple’s own materials from the period cite concrete speedups in pro apps on quad‑core G5 hardware, and the later Mac Pro continued that trend on Intel silicon while Rosetta eased the PPC→Intel transition. (apple.com)

Summary: the CHUD hint was one piece of an evolving story — dual‑core PowerPC silicon existed on IBM’s roadmap and Apple briefly shipped quad‑core Power Mac G5s in late 2005, then completed the switch to Intel‑based dual‑dual‑core Mac Pros in August 2006.

Omg quad processors, awesome! Apple does it again for hardware, but as for the software battle...well, not good.

Mmm.... Dual-core Quad Processors..... or... Quad-core Dual Processors! Heeheeheehee!!! :)
