While we may not have any knowledge on the GPU's for the consoles, we can make some educated guessing based upon the PC tech that is spawning these...
So far, the 6800Ultra SLI scored 7200 on 3Dmark05. The 7800GTX (G70 which the RSX is based on) came in at 7800. Assuming that the comment that NVidia made about the RSX having about 50% more power than the 6800Ultra SLI, then we can guess that it would (theoretically) score around 10800 (1.5 times the SLI score).

Now, the R520 (which the R500 is based on) scored over 10000 itself, while running 24 of it's proposed 32 pipes.

Now, here we have the R520 running at 75% power, but still having more than 30% performance over the G70 and this thing isn't even half the power of the R500 while the G70 is suppose to be 2/3rd the power of the RSX.
I think that we can easily make an educated guess here that says the RSX is outclassed.
