Comparison of Transfer Technology Performance
The table below shows a summary of the theoretical maximum system performance of
the various cache technologies at different system bus speeds. It is theoretical because
it is only possible with a chipset that supports it, fast enough cache memory and other
factors. Note how, interestingly, synchronous burst is the best at the 60 and 66 MHz bus
speeds common on so many Pentium machines today. Despite this it is not nearly as common
as pipelined burst cache. Fortunately, PLB cache is only slightly slower, and holds more
potential for use at the higher system speeds that should take the market by storm in
