Yep 32 TMUs with the traditional design.
Now they could've also changed the Addressing/Filtering ratios if that is a correct 'PR' tex fillrate number, but it's not reflected in that 3DMK06 result at Extreme systems, which would make me believe 32TMUs.
As for the SPUs I still think 800 is an asymmetric number so unlikely, I still think 480 with some slight differences in either the composition of the SPUs or in their clocking. I have a feeling we're going to see a re-organization of composition of the SPUs to aide efficiency.
BTW, 19.6GT/s was the textel fillrate of the GF8800Ultra running @ 612Mhz with 32TMUs (FYI R600 was ~ 12 GT/s).
Come to think of it, I'm thinking that the FX guys put the RV770XT/HD4870 fillrate number in it's place on their site and that's what Nordic is calculating from, because guess what the fillrate is when the speed is 750Mhz (the expected XT/4870 launch speed). This guessing may be getting easier.
