The AMD Phenom II X4 650T was a desktop processor with 4 cores, launched in July 2011. It is part of the Phenom II X4 lineup, using the Zosma architecture with Socket AM3. Phenom II X4 650T has 4 MB of L3 cache and operates at 2.7 GHz by default, but can boost up to 3.2 GHz, depending on the workload. AMD is making the Phenom II X4 650T on a 45 nm production node using 904 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on Phenom II X4 650T, which limits its overclocking potential. With a TDP of 95 W, the Phenom II X4 650T consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR2 and DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1333 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Phenom II X4 650T uses a PCI-Express Gen 2 connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability. Hardware virtualization is available on the Phenom II X4 650T, which greatly improves virtual machine performance.
"Zosma" is a die harvested "Thuban" design, and thus physically features the full six cores of "Thuban" which some motherboard models can unlock. Cores can be locked for a variety of reasons and aren't guaranteed to function properly when unlocked.
