The AMD Athlon II X3 455 was a desktop processor with 3 cores, launched in December 2010. It is part of the Athlon II X3 lineup, using the Rana architecture with Socket AM3. Athlon II X3 455 has 512 KB of L2 cache per core and operates at 3.3 GHz. AMD is making the Athlon II X3 455 on a 45 nm production node using 300 million transistors. The multiplier is locked on Athlon II X3 455, which limits its overclocking potential.
With a TDP of 95 W, the Athlon II X3 455 consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR3 memory with a dual-channel interface. For communication with other components in the computer, Athlon II X3 455 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 Athlon II X3 455, which greatly improves virtual machine performance.
