I just wanted to provide a quick summary of what I found today Monero Mining with All-AMD setups. The test system was an AMD Ryzen 7 1700 system (Gigabyte AX370 Gaming 5) with 32GB DDR4-2666 (2x 16GB) and an RX 480 and RX 470 installed.

Monero Mining Performance for Each Option
Total Hashing Power
  • CPU: 483H/s
  • RX 480: 624H/s
  • RX 470: 535H/s
  • Total: 1642H/s
Total Power Consumption While Mining
  • CPU Only, NVIDIA 610 PCIe x1 GPU installed: 133W
  • CPU + RX 480: 225W (delta 92w however NVIDIA card uninstalled)
  • CPY + RX 480 + RX 470: 348W (delta 123W)
Two modifications to up this slightly by lowering power would be switching to a single 4GB DIMM and going from two SSDs to one small and low power m.2 SATA SSD. Those two swaps may lose as much as 6w over what we have above.

Net efficiency
  • 4.72H/s per Watt
That is good, but not great. You can get dual Xeon E5 V4 systems to push around 5.7H/s per Watt. It is much better than the average Xeon D and NVIDIA system.

Suggested Configuration
Total: ~$1040. There have been a few deals for low-cost RX 480's in the $150 range. If you are going mining-only, that is the best option. That would bring the total down to around $920. I got the 8GB model so that I could potentially use them later. The whole setup is essentially silent from 3m which was another goal for me.

Final Thoughts

If you want to understand why adding additional GPUs to a low-cost motherboard is popular, look no further. If you are adding 600H/s for $150 or so the cost of the motherboard/ case/ RAM/ and PSU start to be distributed better.

For our money, get the RX 480 over the RX 470. Adding 16.6% more performance at around the same power consumption is worth it, especially if the price difference is minor.
