The AMD Sempron LE-1250 was a desktop processor with 1 core, launched in October 2007. It is part of the Sempron lineup, using the Sparta architecture with Socket AM2. Sempron LE-1250 has 512 KB of L2 cache and operates at 2.2 GHz. AMD is building the Sempron LE-1250 on a 65 nm production process, the transistor count is unknown. The multiplier is locked on Sempron LE-1250, which limits its overclocking capabilities.
With a TDP of 45 W, the Sempron LE-1250 consumes typical power levels for a modern PC. For communication with other components in the computer, Sempron LE-1250 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.
