I've been off the mining topic for a while, what GPU nowadays would yeld better profits, Vega 56, RX 5600 XT or GTX RTX 2060? And on what algo?

Hi, my rig is Win 10, Ryzen 2600, RAM 2x8GB 3000MHz 16-20-20-38, huge pages on. Im using XMRig for RandomX mining, my speed results are about 2200 H/s reported by NiceHash Miner and 2600 H/s 15 min. avg. from XMRig, config for 6 threads, on 8 i was getting lower results.
I read that users of Ryzen 2600 were achieving over 4000 H/s. What can i do to have similar speeds?
