文章中说了,CUDA core 只是逻辑概念,对应的是 SP,硬件上的 SM 才是比较接近完整意义上的内核。

That's one of the breakthroughs of Fermi. Physically, it is 256SP, but it can do 512 instructions per cycle. That's right, CUDA core is logic core. In other words, gf100 doubled IPC efficiency of gt200 without much increase of physical units. |
