Rumor: Wii U Leaked Specifications

What’s an E3 announcment without some rumored hardware details for an upcoming console? These were originally shown on Vgleaks and posted on NeoGAF:

IBM 45nm Tri-core PowerPC (Power7) processor
3MB L2 Cache
Core 0: 512KB
Core 1: 2MB
Core 2: 512KB
L3 eDRAM cache unknown
Clockspeed unknown

1.5GB (3GB for devkits)

AMD GPU7 R700-Based processor
“GX2” named API for Wii U
32MB embedded DRAM capable of 720p 4x MSAA or 1080p rendering in a single pass

Detailed features of GPU

  • Unified shader architecture executes vertex, geometry, and pixel shaders
  • Multi-sample anti-aliasing (2, 4, or 8 samples per pixel)
  • Read from multi-sample surfaces in the shader
  • 128-bit floating point HDR texture filtering
  • High resolution texture support (up to 8192 x 8192)
  • Indexed cube map arrays
  • 8 render targets
  • Independent blend modes per render target
  • Pixel coverage sample masking
  • Hierarchical Z/stencil buffer
  • Early Z test and Fast Z Clear
  • Lossless Z & stencil compression
  • 2x/4x/8x/16x high quality adaptive anisotropic filtering modes
  • sRGB filtering (gamma/degamma)
  • Tessellation unit
  • Stream out support
  • Compute shader support

6 Channel HDMI
120MHz Audio DSP

802.11 b/g/n
4x USB 2.0
512MB SLC NAND reserved for Wii U
8GB MLC NAND for Applications

Finally, some bad news. The Wii gamepad (or WiiPad as many are now calling it) has an estimated battery life of only 3-5 hours, meaning you may have to charge it during motion gameplay. Also, hooking two of the WiiPads together on the same Wii U will cause the frame rate to drop from 60fps to 30fps.

We’ll keep you posted.
