well technically it is one processor, but with more than one core. maybe he doesnt talk english  and when translated it turned out this way? there is no way the Wii U has a single core processor and produce graphics like that

No, it is almost certainly not 2 times the work, due to the reasons I pointed out.

Also note, that from a computer science standpoint, it is extraordinarily unlikely that double a screen's resolution of any rendering system will 1/2 the frame rate.  Increasing the resolution pretty much ONLY affects the fragment (or pixel if you prefer) shader's performance as more fragments are sent to the shader for processing, the vast majority of individual time slices that compose the frame's render time will not care about the resolution what so ever.  Fragment shaders are a significant chunk of the total fram time, but certainly not 100% and probably not 50% for most games.

Actually, I believe that the rumored memory footprint of the OS is incorrect. PS360 reportedly have numbers inferior to 80~100 MB. Even a full multitasking OS (like some flavour of Linux), won't use more than 300 MB. I expect that the os will use less than 200 MB with optimizations coming via firmware updates reducing this usage to less than 100 MB. 

Probably, the tablet won't use any of this. I believe that a lot of games will use the tablet for menus, inventory and secondary functions, so it won't be necessary to process complex graphic information there. Games with lower hardware requirements could use the tablet for more refined, resource-intensive tasks.

Why is not Galaki here dooming Nintendo? :(

I remember when I was talking to these guys, I was saying that the Wii U was going to be more powerful than the PS3 and 360 and no one believed me. They didn't think it really had any chance of that (for I don't know what reason). People who claim they have researched into this stuff and know its capabilities can be dead wrong. We all know that it will be more powerful than the PS3 and 360 now. Who's right this time, I don't know. I just get irritated when the majority of people get stuff wrong because they believed the rumors they heard as truth.

So the tablet won't have a processor...wasn't that the same limitations MS had to deal with when they introduced the Natal? They striped the processor out of it and it became the weaker Kinect.

If I remember correctly, it has no independent graphics processor, just a small cheap processor to handle input, to manage actual screen functionality, and to handle the "power off" functionality of the tablet (like universal remote capabilities)

Can't do any of that without SOME processor

I always got Takahashi confused with Microsoft's Shane Kim, but that's aside the point.

You're not getting it. I know how a GPU works and what all the parts do, and the effect on performance. All that is nothing to my actual point that a "single processor" operating on a 2x larger screen is still 2x the work for a completely different image of equal complexity being on the other half (notice I said it's NOT 2x the work for a blank screen, and infer that there is a gradient of work between those two if some is shared), while the OP article claims it's insufficient as if 2 GPUs would be better when they are not due to overhead.

Also thre is no such thing as a fragment shader or vertex shader any more. All the computational units can perform both tasks.

I was going to post this but couldn't be bother to look for who Takahashi is.

Sounds like I was right to not post since he is unlikely to know how to code "Hello World!" in html. I can't defend that.
