Still remember codename Zosma? It is a new Phenom II quad-core processor line based on the same six-core Thuban silicon, but with two cores disabled. Beside the two "potentially" unlockable cores, Zosma also brought the AMD's Turbo Core technology, which previously only found on Six Core Phenom II.
Phenom II X4 960T Black Edition "Zosma" recently spotted at Japan market. This quad-core chip with unlocked multipler comes with the part number HD96ZTWFK4DGR, and is sold in PIB (processor in a box) packages. The chip was tested to allow unlocking of the disabled fifth and sixth cores, proving it's based on the Zosma silicon. It comes with a stock clock speed of 3.00 GHz (15 x 200 MHz), but can bump clock speeds up to 3.40 GHz (17 x 200 MHz). The chip features 512 KB of L2 cache per core, and 6 MB of shared L3 cache.
