SI != NI :sneaky:
I said next part... and Charlies says "Southern Islands (SI) is a 40nm family, and from early information, it looks to be a hybrid between Evergreen and Northern Islands. The architectural details are quite slim now, but it looks like ATI took the uncore from NI and put the shaders from Evergreen on it. Think of it as taking the parts that were done and available, and putting them together."
