The AMD Athlon 64 LE-1640 was a desktop processor with 1 core, launched in October 2007. It is part of the Athlon 64 lineup, using the Windsor architecture with Socket AM2. Athlon 64 LE-1640 has 1 MB of L2 cache and operates at 2.6 GHz. AMD is making the Athlon 64 LE-1640 on a 90 nm production node using 227 million transistors. The multiplier is locked on Athlon 64 LE-1640, which limits its overclocking potential.
With a TDP of 45 W, the Athlon 64 LE-1640 consumes typical power levels for a modern PC. AMD's processor supports DDR2 memory with a dual-channel interface. For communication with other components in the machine, Athlon 64 LE-1640 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 LE-1640, which greatly improves virtual machine performance.
