I sell and design in SDRAM,DDR, and RAMBUS every day from the largest Worldwide memory mfg. I agree with most of this article, however, DDR bandwidth bandwidth appears to beat RAMBUS with much fewer costs. The costs are speed related regarding the test equipmeent, board layouts, and the low production rates currently on RAMBUS. DDR, DDR2 and QDR look very good for the next generation desktops using PC266 DIMM modules. RAMBUS is todays Mercedes and look out Lexus (DDR)is coming and they are cheaper.
RAMBUS is a pretty good solution today,but with DDR (not to mention DDR2 or QDR) the Desktop industry doesn't care much about a couple of extra watts if its cheaper. We don't either especially if it works better
