The AMD Sempron 3400+ was a desktop processor with 1 core, launched in May 2006. It is part of the Sempron lineup, using the Manilla architecture with Socket AM2. Sempron 3400+ has 256 KB of L2 cache and operates at 1800 MHz. AMD is building the Sempron 3400+ on a 90 nm production process using 81 million transistors. The multiplier is locked on Sempron 3400+, which limits its overclocking capabilities.
With a TDP of 62 W, the Sempron 3400+ consumes typical power levels for a modern PC. For communication with other components in the machine, Sempron 3400+ 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.
