Wii U's GPU Revealed

Digital Foundry has put together a comprehensive piece outing new technical details for Wii U. The information was deciphered thanks to reverse-engineering photos provided by Chipworks. Click here to read the full article.

- Wii U GPU core: 320 stream processors, 16 texture mapping units, 8 ROPs

- GPU: close match to the Radeon HD 4650/4670

- Defecit in the number of texture-mapping units and a lower clock speed
- 550MHz clock speed

- “GCN hardware in Durango and Orbis is in a completely different league”

- RV770 does have 16 TMUs at 550MHz and texture cache improvements

- This puts it past Xbox 360′s Xenos GPU

- It’s 1.5 times the raw shader power

- 1080p resolution is around 2.5x that of 720p, so it’s unlikely that we’ll be seeing any complex 3D titles running at 1080p

- Some Wii U ports may be disappointing tecnically due to Wii U’s 1.2GHz CPU

- Nature of the second and third banks of RAM is currently unknown
