DDR-SDRAM Has Finally Arrived


Due to unfortunate constraints that were partly due to unsatisfying support by AMD we weren't able to run a full-blown scientific test suite, as I would have liked. Still we should see a clear advantage of the DDR-platforms in applications that need a lot of memory bandwidth, such as e.g. 3D-games. However, we should also not forget the days of the BX-introduction , when the 50%-increase in memory performance (from 66 to 100 MHz FSB) hardly showed in any benchmark.
