This Sapphire Pulse Radeon RX 560 4GB graphics card is the first I've put on test for mining ethereum.
Bought it at about $190 at local Tbilisi electronics shop, but you could get this card from Amazon for about $130.
Out of the box, I was able to get 10.72MH/s for Ether and 85.74 MH/s for dual mining Siacoin, on average by mining with this card only I'm able to make about $0.98 daily, which gives about 190 days for ROI. See: I'm Making $0.98 Per Day By Mining Ethereum and Siacoin, and I want MORE!
Cat waiting for the first mining rig to be built
Currently, this card is installed on a desktop PC (single graphics card mining) and while it was in closed tower noticed following measurements for temperature and fan speed
- 75 Celsius
- 48% Fan speed
As I was not happy with +75 Celsius, I decided to remove the cover and shortly temperature and fan speed dropped:
- 67 Celsius
- 27% Fan speed
Now, I believe lower temperatures and slower fan speed will extend the total lifetime of for this card. And that's great.
I haven't yet performed optimization for this card (overclocking) but I believe it's possible to get about 10% improvement for it.
