I have been offered a few R9 380's 4GB - anyone know what the up todate expected hashrate is of these cards please?
many thanks
About the same as 280 or 280x (210 to 300 sol/s)
Watts per card are also pretty high so consider it as winter heater or if your electricity cost is really cheap only.
If they are anything like the R9 390's then I'd give them a miss.
I had R9 390's and with the amount of heat they gave out I could have turned the room the rig was in into a sauna.
I had to use two power supplies to run the rig with the R9 390's, they take lots of juice to run, hope he has cheap electricity.
I have a few R9 390. I run them at low voltage. It is quite efficient, about 2H/J. But it is lower than 1080Ti.
