Can't remember the specifics but do remember thinking at the time : that I apparently wasn't missing anything.. Yes, but... REAL WORLD is just another way of saying 'my application'. If you run data-intensive memory-walking codes, typical of scientific computations, SDRAM is a substantial win. If you run mostly from cache or random uncached locations, SDRAM is a wash. For my own typical applications, the REAL WORLD performance of SDRAM is substantially better than FPM/EDO/BEDO.
