Um, that's for 550MHz - when you see someting like 480:24:8 config, it means - 480 Shaders, 24 TMUs (Texture Mapping Units), 8 ROPs (Render Output Unit). So you take the clock, divide it by 1000 (to get to giga instead of mega) and multiply with config - 24*.55GHz gives 13.2 GTexels/s; 8*.55GHz gives 4.4GPixels/s; 480*.55GHz gives 264 GOperations/s - now for the GFLOPS part - each AMD's shader can do multiply + add at the same time, which in this case gives 264*2 = 528 GFLOPS (single presicion). Notice how 360's and PS3's Shader operations per second are not related in same manner to their GFLOPS numbers - this is due to different Shaders, so math is bit different (specially for RSX inside PS3).

ok thanks for the info, now i understand it a lil bit better how it works

so its just basically the shaders that push the WiiU GPU beyond current gen consoles

Yes, that's what makes it stronger - amount and somewhat newer architecture (specially in the case of PS3, which does not have unified shaders, which means it has separate shaders for pixel and vertex operations). Above that, it seems that WiiU's GPU is DirectX 11 equivalent, so, although not very powerful per se compared to what (most likely) MSony consoles will have, it is still more easy to port to it than to PS360.

Of course, it's a real shame that CPU and memory bandwith are not spec'd higher, that would really make WiiU stand out right from the start, and be way better future proof.

EDIT: Just to clarify - this does not mean that WiiU is 2x more powerfull than PS360. If you look at raw numbers, PS3 has theoretical 400.4 GFLOPS in GPU and 179.2GFLOPS in Cell for total of 579.6 - which is more than WiiU; plus, it's pixel and shader fill rates are same as WiiUs. But this is just in theory - in practice, WiiU's GPU IS more powerfull than PS360 (just don't forget that it's shader performance is that, not necessarily overall performance). As for the whole system - it is maybe too soon to tell, but it seems that CPU will give lot of headaches to 3rd parties...
