Hi Antimo, short answer based on my personal experience with the gtx1050 is: yes, speed-up is clearly observable and I would say significant, much lower than V100 or any other hpc GPU though. If you want some numbers I remember a benchmark I did a year ago limited to the V_xc calculation in PW (a few density FFTs per SCF step and some loops on the density grid). For a small test (water molecule) on 1 MPI I obtained about 2x with respect to CPU only on my laptop, while I got 8-9x on a V100 system. From what I could see and hear from other people (not much) acceleration is observable starting from Pascal (cc60) architecture onwards, regarding 'non-hpc' GPUs. Honestly I never went further than this, but I doubt that single precision mostly based GPUs could provide advantages in terms of performance/consumption. But my technical knowledge on this is very limited, so I don't want to provide any definitive statement.

Or in other words, is the speedup provided by GTX 1050 significant? Especially considering the relative poor performance these cards have in double precision. These cards cost an order of magnitude less than top-notch HPC GPUs, so it would be interesting for people to know whether the speed/price is actually potentially interesting. Thank you!

You just need to download the hpc_sdk toolkit. Of course you are limited to small calculations and I often find troubles when I try to run 2+ MPI on the same GPU. But you can certainly give it a try.
