The AMD K6-2+ 475ACZM was a mobile processor with 1 core, launched in April 2000. It is part of the K6-2+ lineup, using the Sharptooth architecture with Super Socket 7. K6-2+ 475ACZM has 128 KB of L2 cache and operates at 475 MHz. AMD is making the K6-2+ 475ACZM on a 180 nm production node using 21 million transistors. The multiplier is locked on K6-2+ 475ACZM, which limits its overclocking potential. With a TDP of 13 W, the K6-2+ 475ACZM consumes very little energy. The highest officially supported memory speed is 100 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). For communication with other components in the system, K6-2+ 475ACZM uses a PCI-Express N/A connection. A lot of games will not work on this processor, because they require the SSE instruction set, which is not supported.
