AMD would be releasing its 45nm silicon-based desktop CPUs, built on the Deneb, Propus, Heka, Rana and Regor cores, to bring out quad-core, triple-core and eventually dual-core processors. AMD has discarded the 5-digit number scheme that was earlier reported, and in its place, adopted a three-digit scheme. The quad-core Deneb chips get a 9xx model number and 8xx number depending on the clock-speeds and cache size, Propus-based chips get the Athlon X4 branding.

Heka-based chips get Phenom II X3 7xx branding, with Rana getting Athlon X3 4xx. Regor dual-core trails with Athlon X2 2xx. It is important to note that AMD seems to have made a critical change to the Deneb core, releasing 2 models based on cache-arrangements. The first kind features a total of 8 MB cache (4x 512K L2 + 6M L3) and one with 6 MB total cache. To learn more about the other cores, please refer to our older article getting into details (here).There's a bit about the processors' launch schedule given as well, all the purple marked numbers are AM3 package based, while green ones are AM2+. Another slide reveals that AMD will come up with a multiplier-unlocked Phenom II X4 940 Black Edition (AM2+) in Q1, 2009. AMD itself projects this chip to have overclocking potential far beyond 4.00 GHz on liquid-cooling, which it describes as "Massive Headroom". We're trying to source larger images at the moment.
