The AMD Athlon X2 7550 was a desktop processor with 2 cores, launched in December 2008. It is part of the Athlon X2 lineup, using the Kuma architecture with Socket AM2+. Athlon X2 7550 has 2 MB of L3 cache and operates at 2.5 GHz. AMD is building the Athlon X2 7550 on a 65 nm production process using 450 million transistors. The multiplier is locked on Athlon X2 7550, which limits its overclocking capabilities.
With a TDP of 95 W, the Athlon X2 7550 consumes a good deal of power, so decent cooling is 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. Actual memory technology support depends on the chosen motherboard, the processor itself supports multiple memory types, but most motherboards have only one kind of slot. For communication with other components in the machine, Athlon X2 7550 uses a PCI-Express N/A 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 X2 7550, which greatly improves virtual machine performance.
