Reportedly, Callisto will be based on the 45nm Deneb core that's inside AMD's new Phenom II X4 processors. Just like with the current, Phenom-derived Athlon X2 7750, AMD will simply disable two cores and keep the shared L3 cache intact (6MB in this case). Considering Deneb can match 45nm Core 2 Quads, Callisto could be a formidable competitor to Intel's low-end Core 2 Duo and Pentium processors.
Rumor: AMD prepping dual-core Callisto with 6MB L3
