RE: <Sorry, the independent benchmarks of Rambus all show them being slower than Sdram. So it's reasonable to expect that they'll be even slower against DDR. Nope, sorry, gotapex reversed the results of their first review (after they received new drivers) and added that the 820 will be a winner.>

Nope, sorry, got apex didn't reverse the results. The new drivers allowed Rdram to get closer than it was with the old drivers and to slight nudge ahead in Quake III. The actual results are:

3DMark, 1024x768, 32b: Rambus 10.3% slower
3DMark, 640x480, 16b: Ramus 0.2% slower
Synth CPU, 1024x768, 32b: Rambus 0.9% slower
Synth CPU, 640x480, 16b: Rambus 0.1% slower
Quake III (ave across all): Rambus 1.7% faster

Please note that several days ago someone on this thread reported the Quake III results as 3-6% faster since he scaled up from 533 MHz to 550 MHz. This scaling is not valid. It is true that Got Apex compared 533 MHz Rambus numbers against 550 MHz Sdram numbers but the reason he did that is because the 533 MHz Rambus numbers are slightly faster than the 550 MHz Rambus numbers. You can see this here:
gotapex.com
Here is his explanation: "Needless to say, the 533B performs within a frame or two per second of the 550mhz processor (the 533B tends to be SLIGHTLY faster because of the 133mhz system bus) which performs within a frame or two of the 500mhz processor, given the same motherboard."

As for the 820 being a winner, please note what he said: "The i820 will be a success because of Intel's marketing muscle and overwhelming market share." Now that's a great testimonial!

As for these results, the guy does say that the new drivers are still not the final ones and he expects further improvement with the production drivers.

I do expect that the Rambus system will be shown slightly faster when everything is final. I don't see how any memory could be so slow as to lose out in 3D benchmarks while having 4xAGP on its side. So, of course, this is really in the "Contrived comparison" category since it is comparing the fastest Rdram with the newest chip set against the old generation chip set and Sdram. Rambus really should be winning by a large margin in these tests if it is any good at all.
