The AMD Athlon 64 2650e was a desktop processor with 1 core, launched in January 2009. It is part of the Athlon 64 lineup, using the Lima architecture with Socket AM2. Athlon 64 2650e has 512 KB of L2 cache and operates at 1600 MHz. AMD is building the Athlon 64 2650e on a 65 nm production process using 122 million transistors. The multiplier is locked on Athlon 64 2650e, which limits its overclocking capabilities. With a TDP of 15 W, the Athlon 64 2650e consumes very little energy. AMD's processor supports DDR2 memory with a dual-channel interface. For communication with other components in the machine, Athlon 64 2650e 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 2650e, which greatly improves virtual machine performance.
