Labs secured an early Cyrix 6x86 system to test whether it lives up to expectations. Labs for performance testing. Four of each type of system had clock speeds of 150MHz. Our mission was to identify the fastest systems and determine which ones offer the best price-performance combination. Finding the best performance for your dollar can be tricky.
Clock speed offers little indication of actual performance.
And the fastest 166MHz Pentiums performed less than 25 percent faster than the baseline 133MHz system. Performance differences between Pentium Pro systems were greater, but again, clock speed gave few clues to real performance. Dimension XPS Pro200. All Up Prices also vary widely, especially across chip families. Also, Intel's PCI chip set, used in most Pentium Pros, can't use EDO RAM to boost performance.
