I see that 1.05 have relatively high needs for memory bandwidth.

That makes sense: the look-up table has to be used intensively, otherwise it woudln't help speeding things up (normally). and we know from Bernds post it's requiring about 100 MB of RAM (per instance), i.e. a lot more than any current CPU cache offers, so those values must be fetched from main memory.

Yes, but it wouldn't be a problem for a GPU memory.  I will hazard a guess that they wouldn't bother with optimizing a CPU app so late in the game unless they had GPU plans for it along the same lines.
