-The biggest change is in the shaders, they have gone from a 4 simple + 1 complex arrangement to a 4 medium complexity arrangement. This should end up no slower than the old way for simple calculations, the overwhelming majority of the workload, but also be faster for most of the complex operations.
-Since the shader count is 80% of the old grouping, there is some space saved, and on top of that AMD has had a lot of time to optimize area. On the down side, each shader is marginally bigger, but the end result is a cluster of four new shaders that is smaller than the old 4+1 group, and faster too.
-The uncore, or at least unshader is beefed up as well, with some very notable efficiency gains as well. The net result should be vastly better utilized shaders as well, so performance should go up incrementally there too. Throw in a few more shader groups, and you have a notable speed increase from the NI family.
-The down side is size. More shaders, smaller though they may be, and a beefier front ends adds up to a larger die. If this part was on 32nm, it would be smaller and probably would have had more shaders as well, but the backport had a price. The net result is that the die of NI will grow by about 10-15%, lets call it around 380-400mm^2. Performance on the other had should grow disproportionately, with the few weak spots of the Evergreen architecture smoothed over. That is what the game is about, isn't it?
