The AMD Athlon 64 X2 6000+ was a desktop processor with 2 cores, launched in February 2007. It is part of the Athlon 64 X2 lineup, using the Windsor architecture with Socket AM2. Athlon 64 X2 6000+ has 1 MB of L2 cache and operates at 3 GHz. AMD is building the Athlon 64 X2 6000+ on a 90 nm production process using 227 million transistors. The multiplier is locked on Athlon 64 X2 6000+, which limits its overclocking capabilities. With a TDP of 125 W, the Athlon 64 X2 6000+ consumes a lot of power, so good cooling is definitely needed. For communication with other components in the machine, Athlon 64 X2 6000+ 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. The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability. Hardware virtualization is available on the Athlon 64 X2 6000+, which greatly improves virtual machine performance.
