AMD K6-III+ and K6-2+ Shaptooth's Final Bite
(Review by Aaron Vienot, July 13, 2001)

Since the K6-III+ is an obsolete product, this article is more a retrospect on the most powerful CPU that ever roamed the Socket7 world with the added benefits of producing less heat and offering significant overclocking capability. Some have reported that clock-for-clock the K6-III+ is actually a touch slower than the K6-III, but then, few if any K6-III CPUs made it to 560MHz, and certainly not to the 600, 612, and 672MHz clocks reportedly achieved by some owners.

Other than die size, the primary physical difference between the two processors tested here is the 256kB of on-die L2 cache. Yet even in the relatively complex Q3A, the K6-III+ still performed significantly better than the K6-2, demonstrating just how much that cache is worth. As stated in an earlier review, the difference between the K6-III and its shrunk version on the one side and any other CPU out there is the incredible crispness of its operation. That is, in multitasking situations, there is hardly any CPU that switches as smoothly between windows as the K6-III. This is certainly worth a consideration when raw performance is not the only criterion. In the world of CPUs, if there is any analogy possible, the K6-III would be a 2-stroke street bike. There are faster things in the world but hardly anything beats the bite of the last Sharptooth.
