Phoronix published a review on the NVIDIA GeForce GTX 460 vs. 760 vs. 960 vs. 1060 Performance
A quote from the article:
To complement yesterday's launch-day GeForce GTX 1060 Linux review, here are some more benchmark results with the various NVIDIA x60 graphics cards I have available for testing going back to the GeForce GTX 460 Fermi. If you are curious about the raw OpenGL/OpenCL/CUDA performance and performance-per-Watt for these mid-range x60 graphics cards from Fermi, Kepler, Maxwell, and Pascal, here are these benchmarks from Ubuntu 16.04 Linux.NVIDIA GeForce GTX 460 vs. 760 vs. 960 vs. 1060 Performance @ Phoronix
The x60 cards I have in my possession going back to Fermi are the GeForce GTX 460 Fermi, GTX 760 Kepler, GTX 960 Maxwell, and GTX 1060 Pascal. All of these tests were done with the NVIDIA 367.27 proprietary Linux driver. I didn't go back further than Fermi since that support is provided by the NVIDIA legacy Linux driver. Tests were done from the same Intel Xeon Skylake system running Ubuntu 16.04 LTS with the Linux 4.4 kernel.
