We learnt from AMD that the number of SP inside RV770 isn't 800. Actually, this number is more than 800sp, but AMD hasn't told us the exact number.

But you can image 850 or 840 sp are actually put inside the RV770 chip, AMD only opens 800sp to consumers, the left sp have been shielded.

We hope someone or some software could open the shielded sp for us.

Anyway AMD will shown a live demo of RV770 with a frog as the protagonist.
