En neogaf han conseguido una foto de la GPU de Wii U




En rojo están los (supuestos) shader clusters. En azul los (supuestos) TMUs.

Los otros colores sin nombre no se sabe lo que son. Están esperando a que chipworks, los que sacaron la foto, desvele más información.

Actualización de chipworks:

Bueno, pero no esperéis milagros tampoco XD

WiiU es lo que es...sin mas, igual alguna minisorpresilla hay pero nada brutazacal.

Ahí lo tenéis chicos, el iceberg de Wii U en su máximo esplendor


PD: no, en serio, creo que nadie tiene ni idea de lo que es.

Cita:The stuff we got from Chipworks is extremely low level. Apparently, the parts at the bottom left are both interfaces, though we have no idea what they interface with. The thing on the left has a tank oscillator (no idea what that is, but it's apparently good stuff), and the one next to it is a very high speed interface, potentially SerDes. Don't feel bad if you have no idea what that means, as we have pretty much no idea either.

Thraktor ha hecho el siguiente esquema:


También ha habido algunas especulaciones, pero lo único concreto ha sido lo que ha dicho Chipworks:

Cita:Been reading some of the comments on your thread and have a few of my own to use as you wish.

1. This GPU is custom.
2. If it was based on ATI/AMD or a Radeon-like design, the chip would carry die marks to reflect that. Everybody has to recognize the licensing. It has none. Only Renesas name which is a former unit of NEC.
3. This chip is fabricated in a 40 nm advanced CMOS process at TSMC and is not low tech
4. For reference sake, the Apple A6 is fabricated in a 32 nm CMOS process and is also designed from scratch. ItÔÇÖs manufacturing costs, in volumes of 100k or more, about $26 - $30 a pop. Over 16 months degrade to about $15 each
a. Wii U only represents like 30M units per annum vs iPhone which is more like 100M units per annum. Put things in perspective.
5. This Wii U GPU costs more than that by about $20-$40 bucks each making it a very expensive piece of kit. Combine that with the IBM CPU and the Flash chip all on the same package and this whole thing is closer to $100 a piece when you add it all up
6. The Wii U main processor package is a very impressive piece of hardware when its said and done.

Trust me on this. It may not have water cooling and heat sinks the size of a brownie, but its one slick piece of silicon. eDRAM is not cheap to make. That is why not everybody does it. Cause its so dam expensive

Bueno, pues... Ya se verá. Esto para los de electrónica, más que los de informática
