The AMD Athlon 1100 was a desktop processor with 1 core, launched in August 2000. It is part of the Athlon Model 4 lineup, using the Thunderbird B architecture with Socket A. Athlon 1100 has 256K of L2 cache and operates at 1100 MHz. AMD is building the Athlon 1100 on a 180 nm production process using 37 million transistors. The multiplier is locked on Athlon 1100, which limits its overclocking capabilities.
With a TDP of 60 W, the Athlon 1100 consumes typical power levels for a modern PC. AMD processor supports DDR1 memory. This processor does not have integrated graphics, you will need a separate graphics card.
A lot of games will not work on this processor, because they require the SSE instruction set, which is not supported.
