    New series of GPU cards

    nVidia just seem to have released a GT1030 specially against the Radeon RX 550. What is so special about the Radeon RX 500 series?
    Let's start with the RX 550

    The RX 550 is a very capable card in view of its power needs, a mere 50 Watt. Those willing to spend a little more on purchase and power bills can choose for the even more capable RX 560
    The TBP (Typical Board Power) of the RX 560 is actually 60-80 Watt, so the GFLOPS/Watt may be even better yet.

    What does nVidia offer?

    *=Normal values unknown yet. For the Titan Xp I only know of the 'Turbo boost' values, at the moment.

    Considering the fact that most projects only ask for Single precision, the GT 1030 offers real value. But when we take double precision performance (e.g. MilkyWay) into account, nVidia is fighting a lost battle as they have sacrificed that feature to boost the sales of their professional (Quadro/Tesla) cards. I do not know yet of the effects of the half-precision performance, but nVidia seems to have made the wrong choice there too by offering Half-precision at 1/64th of the Single precision while AMD offers it at the same GFLOPS as the single precision. There ought to be projects where AMD cards smash the nVidia cards, performance-wise.
