The AMD Phenom II X6 1055T (95W) was a desktop processor with 6 cores, launched in May 2010. It is part of the Phenom II X6 lineup, using the Thuban architecture with Socket AM3. Phenom II X6 1055T (95W) has 6MB 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 building the Phenom II X6 1055T (95W) on a 45 nm production process using 904 million transistors. The multiplier is locked on Phenom II X6 1055T (95W), which limits its overclocking capabilities.
With a TDP of 95 W, the Phenom II X6 1055T (95W) 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 MHz, 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 (95W) uses a PCI-Express Gen 2 connection. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Phenom II X6 1055T (95W), which greatly improves virtual machine performance.
