Athlon II X3 400e has 512 KB of L2 cache per core and operates at 2.2 GHz. AMD is building the Athlon II X3 400e on a 45 nm production process using 300 million transistors. The multiplier is locked on Athlon II X3 400e, which limits its overclocking capabilities.
With a TDP of 45 W, the Athlon II X3 400e consumes typical power levels for a modern PC. AMD's processor supports DDR3 memory with a dual-channel interface. For communication with other components in the machine, Athlon II X3 400e 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 400e, which greatly improves virtual machine performance.
