Hi,
indeed I confused the RK3399 / k and RK3399pro, I didn't think too much.
I am not formalizing myself on the possible improvements, but it is always desirable to consider all the solutions when this one exists, for my part I really have nothing to say about the hardware choice of the Helios64.
Certainly shouldn't i trust the Vray but the card seems to me very well balanced, and the components brilliantly distributed on the PCB, it inspires confidence.
I went through the helios4 wiki, it's wonderful, you give so much, it's not only a solution, it's also an education. I'm starting to imagine my bundle helios64, cluster with 4 helios64 in a 10" rack cabinet.
Is it serious doctor ?
I will be very attentive to your next achievements.
off topic I first do my CNC wood / metal 1300x1550 / 1900 for the workshop Q3 2020, 3D polymer not before Q1 2021 so I'm in no rush.
