While Apple hasn't yet released its first Intel-based professional model desktop machine, many users are actively watching Intel's future roadmap for hints as to what may next appear in Apple's second revision mac pro and XServe machines. CNet News.com reported yesterday afternoon that Intel's quad-core desktop chip (Kentsfield) and Xeon-class chip (Cloverton) have been bumped up and should arrive before year's end. Educated speculation would therefore indicate that Apple's second revision Mac Pro workstation will feature 8 cores, and other models will all become "Quad" machines. Most recent rumors have indicated that the Mac Pro will use Apple's Xeon-class chips over "desktop" models such as Core 2 Duo "Conroe" and Kentsfield. With Conroe perhaps landing in a future iMac, further speculation would indicate that iMacs down the pipe will feature the 4-core Kentsfield processor.
