The AMD Sempron 3100+ was a mobile processor with 1 core, launched in January 2001. It is part of the Mobile Sempron lineup, using the Paris architecture with Socket 754. Sempron 3100+ has 256 KB of L2 cache and operates at 1800 MHz. AMD is building the Sempron 3100+ on a 130 nm production process using 69 million transistors. The multiplier is locked on Sempron 3100+, which limits its overclocking capabilities. With a TDP of 25 W, the Sempron 3100+ consumes only little energy. Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
