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.<br>

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.</span></div>

<div style="line-break:after-white-space">Dear Fabrizio,
<div><br>
</div>
<div>I am very interested in your experience on this, have you ever benchmarked QE PWscf on your “cheap” GTX 1050 versus HPC GPUs such as V100?</div>
<div>Or in other words, is the speedup provided by GTX 1050 significant? Especially considering the relative poor performance these cards have in double precision.</div>
<div>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.</div>
<div><br>
</div>
<div>Thank you!</div>

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.<br>
