一个简单的问题不要弄得太复杂. Tegra2的GPU的Vextex shader和raster是nv4x的, pixel shader是另外设计的, 因为nv4x的PS太大装不进来. Tegra3的主要重点是四核, GPU就是简单的把Tegra2翻倍而已. 到Tegra4,GPU性能终于提上议事日程, VS/PS都在T3的基础上复制6倍(当然还有其它的一些辅助改进). 就这么简单.

Tegra 2的前端是4VS—4PS—1TMU；Tegra 3的是4VS—8PS—2TMU；前面某个温柔善良漂亮可爱的女孩子说了“在 ...

I am not a girl BTW. And 6x is only for VS and PS.

2.5x of what, T30? Come on...

If you lower the clock you could get only 1x of T30. What is the point?
