最后一次相信NV是MCP78U,号称16个SP,大家都知道同工艺下(包含NV的倍频技术)NV每个SP效能基本上等于ATI的5个SP,也就是说MCP78个人估计理论性能与80个SP的ATI整合主板相近!
可实际上呢?别说被40个SP的780G秒( ...

我没听说过 NVIDIA 有这样的说法,在 NVIDIA 的 G80 技术大纲中原文是这样的:
NVIDIA engineers have estimated as much as 2X performance improvement can be realized from a scalar architecture that uses 128 scalar processors versus one that uses 32 4-component vector processors, based on architectural efficiency of the scalar design. (Note that vector-based shader program code is converted to scalar operations inside a GeForce 8800 GPU to ensure complete efficiency.) |
