The AMD Athlon SFF 1200 was a desktop processor with 1 core, launched in October 2001. It is part of the Athlon XP lineup, using the Palomino architecture with Socket A. Athlon SFF 1200 has 256 KB of L2 cache and operates at 1200 MHz. AMD is building the Athlon SFF 1200 on a 180 nm production process using 38 million transistors. The multiplier is locked on Athlon SFF 1200, which limits its overclocking capabilities.
With a TDP of 35 W, the Athlon SFF 1200 consumes only little energy. AMD's processor supports DDR1 memory. The highest officially supported memory speed is 266 MT/s, but with overclocking (and the right memory modules) you can go even higher. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
Many games will refuse to start on this processor due to the lack of the SSE2/SSE3/SSE4 instruction set.
