im not certain what you mean...
rx stands for random x....
id go look at fireice's github for notes on compatibility and driver requirement changes... but... furthermore; you are wasting an exponential amount of power to mine on a gpu vs ANY cpu for the most part...
That was the purpose of randomx... to even the playing field so to speak.
Sorry, it was unclear :-)
RX = randomx on the one hand but i thought it also means RX cards (RX458 ...) as far as i know the software doesnt work with R-cards as 280x ...
You are right, AMDs CPUs are better but i still have some old R9 rigs left :-(
yep. randomx takes advantage of the fact that certain operators (divide, add, subtract, multiply) take certain amounts of time to calculate; and the amount of data that it would need in cache as to be accessed quickly. It is very clever since ASICS would need that very same circuitry, so it would be redundant by nature. at least... this is kind of how I understand it.
yeah... its all about optimizing the intensity so that everything stays on the CPU cache; and you get good performance. If you go over that, performance drops like a rock.
