AMD K5 PR150 - AMD-K5-PR150ABR

150 MHz Rating, 116.7(?) MHz Real
296-pin ceramic staggered PGA with gold-plated heatspreader

This 150 MHz CPU runs at the same bus speed and has the same clock multiplier as K5 133 MHz. Nevertheless, in some tests the processor performs a few percent faster than the K5 133 MHz CPU. This increase in performance was due to changes in the processor core.

150 MHz version of AMD K5 was probably released at the same time as 166 MHz version, but it's difficult to tell for sure because this version was never announced by AMD.
