How many scalar and vector registers has new Radeon? Where can I find specifications of Radeons?

*Originally posted by:*it should be 256 x 64 x 128bit = 256 kB register file per SIMD.**nou**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.

it should be 256 x 64 x 128bit = 256 kB register file per SIMD.
