The AMD Phenom II X6 1055T (125W) was a desktop processor with 6 cores, launched in April 2010. It is part of the Phenom II X6 lineup, using the Thuban architecture with Socket AM3. Phenom II X6 1055T (125W) has 6 MB of L3 cache and operates at 2.8 GHz by default, but can boost up to 3.3 GHz, depending on the workload. AMD is making the Phenom II X6 1055T (125W) 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 X6 1055T (125W), which limits its overclocking potential.
With a TDP of 125 W, the Phenom II X6 1055T (125W) consumes a lot of power, so good cooling is definitely 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. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the computer, Phenom II X6 1055T (125W) 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 X6 1055T (125W), which greatly improves virtual machine performance.
