The Hollywood GPU is reportedly based on the Nintendo GameCube's "Flipper" GPU and is clocked 50% higher at 243 MHz。
我这里没有 wii 的资料,不过有 ngc 的 Flipper 资料。
The GP has the following basic performance specifications:
• 162MHz operation.
• 20M/27M/32M polygons/second peak, depending on feature selection.
• 648M pixels/second peak.
Many features may be enabled at these peak performance rates.
Features Performance
1 vertex color + 1 light + 1 texture 20M polygons/second
No vertex color + 1 texture 27M polygons/second
1 vertex color + no texture (Gouraud shading) 32M polygons/second
Table 1 Polygon performance
All of these polygon performance times include fogged, Z-buffered, transparency-blended pixels. For polygons with
textures, the following additional operations can be performed at peak fill rate of 648M pixels/second.
• Trilinear mipmap-filtered, perspective-corrected texture.
• S3TC compressed textures.
• Single-texture map. |
