essentially that is what they have now but with some baggage. each register is still going to be 128bits with 12 read and 4 write ports. this is about 45% of the shader unit and it contributes a lot of power.
I've read your SP's as SPU's, hope you don't mind

Based on my understanding of the rumors floating around, I think what LordEC911
is talking about is ATI/AMD making one more 10 SIMD engine part on the chip.

Today we have, on the 5870, 20 SIMD engines, 16 wide and each with 5 SP's.
If I remember correctly the SIMD engines are physically grouped as 10 each,
like they were two times a 5770.
This gives us 20x16x5 --> 1600 SP's

Tomorrow we have, if the 6870 rumors of today pans out, 1920 SP's. If we
think that ATI/AMD made things the easy way, then we perhaps will see 3 units
of 10 SIMD engines.
Joint with a 4D rumor we get 30x16x4 --> 1920SP's
