應該是一樣的狀況, 雖然沒有測試, 但780Ti 和780的狀況應該是差不多的

GeForce GTX 780 Ti, on the other hand, gets neutered in the same way Nvidia handicapped its GTX 780. The card’s driver deliberately operates GK110’s FP64 units at 1/8 of the GPU’s clock rate. When you multiply that by the 3:1 ratio of single- to double-precision CUDA cores, you get a 1/24 rate. The math on that adds up to 5 TFLOPS of single- and 210 GFLOPS of double-precision compute performance.
