| AMD K6 166 - AMD-K6/PR2-166ALR | |
166 MHz PR2 rating, 166 MHz real 321-pin ceramic staggered PGA Early AMD K6 processors included PR2 (Pentium II rating) in their name. In the second half of 1997 the PR2 rating was dropped from the part number as the rated processor speed matched real processor speed. This processor was manufactured in April 1997 - just weeks after the K6 processor family was launched by AMD. |
