GPU: Nvidia 1060
CPU: Intel i7 2.6 Ghz
OS: Windows 10 64 bit
Fastest time was with a tile of 240, 135 at 101 seconds but basically anything within a tile range of 240 to 512 is pretty close for the GPU.
Fastest time for the CPU was 32,32 but anything between 8 and 128 is fairly close
Here is a table and chart of my runs. I skipped the 8, 8 for the GPU because it was going to be very long.
| X | Y | GPU (sec) | CPU (sec) |
|---|---|---|---|
| 8 | 8 | 240 | |
| 16 | 16 | 1521 | 241 |
| 32 | 32 | 504 | 240 |
| 64 | 64 | 187 | 246 |
| 128 | 128 | 116 | 258 |
| 240 | 135 | 102 | 289 |
| 256 | 256 | 101 | 308 |
| 480 | 270 | 101 | 468 |
| 512 | 512 | 107 | 888 |
| 960 | 540 | 117 | 1491 |
