Template:mpu K6-2/300AFR-66 was a 32-bit x86 K6-2-based microprocessor designed and manufactured in 1998 by AMD. Manufactured using a 0.25 µm process, this MPU operated at 300 MHz with a FSB of 66 MHz consumed 17.2 W. Note that this is an identical model to K6-2/300AFR with a multiplier of 4.5 instead of 3 designed to support a 66 MHz bus instead of 100 MHz.
