So, being that these graphics cards are running the game at over twice the resolution but at under half the frame rate, and there was (most likely) significantly more effort to optimize for the Console version, it would be fair to say that the HD console's GPUs are (roughly) in the same range as the ultra low end of the R700's performance.
Now ... I think we got sidetracked on the original discussion.
I think that it is highly likely Nintendo would take a higher-end version of this GPU, modify the hardware (most likely) to improve effiency and real world performance, move it from a 55nm manufacturing process to a 28nm (or smaller) process to reduce size, energy consumption and cost, and pair it up with "better" memory.
Most people don't realize that most processors (CPUs and GPUs) perform far below their theoritical limits primarily due to bottlenecks. Some of the more common bottlenecks are too little cache, too small of a bus, or memory that is too slow; and often these are not "fixed" when a processor is released because they technology doesn't exist or is too expensive to use comercially. When you're dealing with older hardware as a base, you can drastically reduce the bottleneck to get performance closer to its theoritical limits
