The AMD Phenom II X4 920 was a desktop processor with 4 cores, launched in January 2009. It is part of the Phenom II X4 lineup, using the Deneb architecture with Socket AM3. Phenom II X4 920 has 6 MB of L3 cache and operates at 2.8 GHz. AMD is building the Phenom II X4 920 on a 45 nm production process using 758 million transistors. The multiplier is locked on Phenom II X4 920, which limits its overclocking capabilities.
With a TDP of 125 W, the Phenom II X4 920 consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR2 memory with a dual-channel interface. The highest officially supported memory speed is 1066 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 X4 920 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 X4 920, which greatly improves virtual machine performance.
