The Intel A100 was a mobile processor with 1 core, launched in June 2007. It is part of the Atom lineup, using the Stealey architecture with BGA 437. A100 has 512 KB of L2 cache per core and operates at 600 MHz. Intel is making the A100 on a 90 nm production node using 176 million transistors. The multiplier is locked on A100, which limits its overclocking potential. With a TDP of 3 W, the A100 consumes extremely little energy. Intel's processor supports DDR2 memory. Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
