It's all about GPU utilization under OpenCL loads.
I have an old s1366 system - 6 core Xeon @ 3800 MHz, PCIe 2.0 x16 slots and GTX 1070 clocked 2050 MHz.
With Windows 10 GPU utilization most of the time was 82-86%, nearly the same with any of new drivers (with some very rare WUs gives GPU load spikes to 90%), bus load was 40-44% (by GPU-Z), PPD was from 570k to 640k and average was 600k.
Linux Mint 18.1 with Xorg drivers 370.28 gives GPU utilization most of the time no lower than 95% - with some WUs it peaking to 97-98%, bus load is 1% (by Psensor), with PPD from 770k to 870k and average above 800k.
Same GPU clocks of 2050 MHz in both cases, with Win 10 was set by EVGA precision, with Linux set by editing xorg.conf with 'coolbits 31' line and adding MHz in Nvidia settings panel.
In both OSes most of current WUs takes single CPU-thread loaded up to the roof - I think faster modern CPU may give even slightly higher GPU utilization level under Linux - with PPD average around 900k with GTX 1070@2050.
