Hop salut les amis!!!!!! Une newz venant de l'alsace (oui oui c'est en France, pas en Allemagne)

c'est en anglais et il y a le lien!i

En gros la WiiU est bcp plus puissante que les consoles actuelles et ne sera semble t-il pas à la ramasse face aux nouvelles consoles Hday 2

Have fun!!!!!!!!!!!!!!!!

GX2 is a 3D graphics API for the Nintendo Wii U system (also known as Cafe). The API is designed to be as efficient as GX(1) from the Nintendo GameCube and Wii systems. Current features are modeled after OpenGL and the AMD r7xx series of graphics processors. Wii U’s graphics processor is referred to as GPU7.
Sound and Audio

Dedicated 120MHz audio DSP.
Support for 6 channel discrete uncompressed audio (via HDMI).
2 channel audio for the Cafe DRC controller.
Monaural audio for the Cafe Remote controller.

Networking

802.11 b/g/n Wifi.

Peripherals

2 x USB 2.0 host controllers x 2 ports each.
SDCard Slot.

Built-in Storage

512MB SLC NAND for System.
8GB MLC NAND for Applications.

Host PC Bridge

Dedicated Cafe-to-host PC bridge hardware.
Allows File System emulation by host PC.
Provides interface for debugger and logging to host PC.

So what do all these numbers and words mean? The part that stands out to me is "Compute Shader Support" and "Tessellation Unit" with both of those features being very prominent in DirectX 11 graphics cards. Tessellation was possible on Xbox 360/PS3 (at a high cost on performance) but has been much improved and more efficient with DirectX 11. These features alone would put the Wii U's custom "GPU7" processor far ahead of what was possible on Xbox 360 and PS3. Compute Shading is what most likely will be used by the GPU's in the PS4 and the next Xbox to take the strain off the CPU but not hampering the performance of the GPU (I realize that this can be referred to a GPGPU, but since all modern PC GPUs have this functionality it's not really necessary to call it that).

Here is a good explanation of the benefits that Compute Shading brings:

Compute Shaders are programs that are executed on the graphics processor. With DirectX 11 and DirectCompute, developers are able to use the massive parallel processing power of modern GPUs to accelerate a much wider range of applications that were previously only executable on CPUs. Compute Shaders can be used to enable new graphical techniques to enhance image quality (such as order independent transparency, ray tracing, and advanced post-processing effects), or to accelerate a wide variety of non-graphics applications (such as video transcoding, video upscaling, game physics simulation, and artificial intelligence). In games, Compute Shader support effectively enables more scene details and realism:

Optimized post-processing effects – apply advanced lighting techniques to enhance the mood in a scene
High quality shadow filtering – no more hard edges on a shadow, see shadows the way you would in real life
Depth of field – use the power of the GPU to have more realistic transitions of focal points – imagine looking through a gun sight or a camera lens
High Definition Ambient occlusion – incredibly realistic lighting and shadow combinations

When you start to put all this information together, it becomes easy to understand why ports of 360/PS3 games will not really benefit much in the graphics department on the Wii U without developers totally rewriting their code. Compute Shading & Tessellation for example is something that you will not be seeing in most or any 360/PS3 ports to Wii U, and not only that but the developers making those ports on Wii U would use the same rules as 360/PS3 by making the CPU do the work that could have be done by the Wii U's GPU and it's newer technology. This will be the Wii U's version of a "lazy port" with it's extra features not even being used.

The good news is that the GPU in the Wii U should be able to accomplish all the effects of the PS4 and next Xbox, with those systems most likely being able to do "more of it" and at faster speeds. However, with the similar technology and features that all next-gen systems will have it's doubtful that the Wii U will get left behind in the graphics race since the difference will not be noticeable enough to warrant actually purchasing another console based on the sole reason of the Wii U not being able to run a certain game like what happened with the original Wii. It's encouraging that we (I say we, but I mean the industry since you could argue that the Wii had the best games this gen) will finally get back to comparing who has the best games and not the best graphics in this coming generation.
