The AMD K6-2+ 450ACZM 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+ 450ACZM has 128 KB of L2 cache and operates at 450 MHz. AMD is building the K6-2+ 450ACZM on a 180 nm production process using 21 million transistors. The multiplier is locked on K6-2+ 450ACZM, which limits its overclocking capabilities. With a TDP of 13 W, the K6-2+ 450ACZM 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+ 450ACZM 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.
