How many scalar and vector registers has new Radeon? Where can I find specifications of Radeons?
it should be 256 x 64 x 128bit = 256 kB register file per SIMD.
Thanks! Is there any doc available about it? I see here radeon has an advantage under gt200.

Is this correct? That's quite a jump from the 16kb/SIMD of the 4800.
5870 : 256 x 64 x 128bit x 20SIMD = 5.24 MB
4870 : 256 x 64 x 128bit x 10SIMD = 2.62 MB
See slide 5 of this presentation : http://sa09.idav.ucdavis.edu/docs/SA09_AMD_IHV.pdf
So the number of vector GPRs have remained the same in a SIMD unit.
Oh, yes, I was thinking LDS, sorry.
