In case anyone is wondering what the RandomX hashrate potential is for the Rock 5B, it spiked to a high of 730.5 H/s, and averaged around 728 H/s. My power usage hovered around 14 watts, bouncing between 13.5 and 14.5 watts, with CPU temps hovering at around 77 Celsius with the Radxa blue passive heatsink (using xmrigCC, because I couldn’t get xmrig to work). To put it into context, a lot of people who use a Raspberry Pi 4B get around 100-120 H/s, and use around 6 watts of power., and on an i9-10885 mini pc with dual channel 2933 DDR4 RAM that I have, I get 4700 H/s at an average of 68 watts and 85 Celsius.
Edit: I’m using the Jammy flavor of Armbian from an NVMe on my Rock 5B.
