Actually, with 1200 MHz RDRAM around the corner (or even available ?) a dual channel RDRAM board might prove to be faster than a DDR one. i850 was quite competitive with DDR solutions (if not superior), even though it was a very castrated RDRAM implementation.
What killed RDRAM was mostly the memory price, and to a lesser extent, its reputation. But today, RDRAM isnt all that more expensive as DDR, so why not ? i'm curious how it will perform, and frankly, I wouldnt be surprised if it ends up being the fastest P4 platform around.
