The AMD Athlon II X4 635 was a desktop processor with 4 cores, launched in January 2010. It is part of the Athlon II X4 lineup, using the Propus architecture with Socket AM3. Athlon II X4 635 has 512 KB of L2 cache per core and operates at 2.9 GHz. AMD is building the Athlon II X4 635 on a 45 nm production process using 300 million transistors. The multiplier is locked on Athlon II X4 635, which limits its overclocking capabilities.
With a TDP of 95 W, the Athlon II X4 635 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 machine, Athlon II X4 635 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 X4 635, which greatly improves virtual machine performance.
