The AMD Athlon 64 2000+ was a desktop processor with 1 core, launched in June 2008. It is part of the Athlon 64 lineup, using the Lima architecture with Socket AM2. Athlon 64 2000+ has 512 KB of L2 cache and operates at 1000 MHz. AMD is building the Athlon 64 2000+ on a 65 nm production process using 122 million transistors. The multiplier is locked on Athlon 64 2000+, which limits its overclocking capabilities. With a TDP of 8 W, the Athlon 64 2000+ consumes extremely little energy. AMD's processor supports DDR2 memory with a dual-channel interface. For communication with other components in the computer, Athlon 64 2000+ 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 2000+, which greatly improves virtual machine performance.
