In terms of efficiency, that is hashrate per kilowatt-hour, which GPU is the best?
Has anyone tried the new Radeon RX Vega 64?
Haven't done any mining but I might invest some on a mining rig although I might mine an altcoin and not bitcoin.
The AMD Radeon RX Vega 64 is the most recent GPU from AMD that just commands mining. Stock, it can mine Ethereum at 33 MH/s utilizing around 200 watts however with a touch of tweaking, the hash rate can be as high as 41 MH/s utilizing as meager as 135 watts! This card is just a creature. They are taking off the racks so ensure you get yours when you can.
