They won't be used in the Wii U at all, infact, Open GL might be closer to what the Wii is using than DirectX, but they're still not the same thing. They DON'T use PC graphics card, and GPUs in consoles have been using tech based on the Graphics cards before the current generation.
Also, almost all the features in DX11 were available in OpenGL way before DX11 came out, it's only because Microsoft put those features in there and then went "Oh look, we've added something new and since it's on Windows, you'll use it". The PS3 uses OpenPL which is similar to OpenGL but not the same, and the Wii U, as I said in the post will use it's own API, it's just developers have found it easy to develop with.
Those specs for the Gamecube are slightly skewed as well, the polygons per second were with textures and effects running at the same time, where as the PS2's were nothing but polies on screen, the GC was estimated to be more around the 70-80 millon mark without
Also, the GC was locked to 640x480 in NTSC regions and 576i in PAL regions by Nintendo, it could probably do more, but that would hinder the performance.
Anyway back on topic
@orion, read page 3 on the 720 is 20% more powerful topic, as I said earlier, only the Xbox consoles and Windows PCs use DirectX, it's irrelivent to other consoles.
$300. Final. I wish nintendo was allowed to put a price for us europeans.
Yeah, it's the reason why the 3DS was so expensive at launch, and why the DSi is so expensive. Retailers literally put whatever price they want and say it's an RRP when Nintendo can't set an RRP in the EU.
MHZ !=Power. They used completely different CPU/GPU set ups that actually were pretty equal in power.
The only real differences between the GC and Xbox were RAM (the Xbox has more) and the API used, the Xbox used Direct X 8, and therefore was easier to develop for, and the GC (and inherently, the Wii) uses it's own API developed specifically for it, meaning it was harder to develop for, it used programmable TEVs instead of Shaders for instance.
Right there's a few things that are needed to help this move along.
1. Consoles don't use PC graphics card, only GPU's based on their tech, they end up being completely different and essentially more powerful.
2. DirectX is only used in Microsoft Products such as Windows and the Xbox brand (which was originally called Project DirectXbox) every other competitor uses their own developed API engine to make full use of the hardware, so it doesn't matter about DX11 and Shader Model 5.0, the Wii itself didn't even use shaders, it used TEVs, the Wii U will use shaders but in it's own way.
3. The Wii U could always add new tech, just because early dev kits were based off of the R770, doesn't mean they are now, and even then, they still had stuff like Hardware Tesselation, also Nintendo has said that the machine can do SterioScopic 3D, which the 4800 series can't do.
