Despite the shady steemit article “Ethereum Mining with Google Cloud (Nvidia Tesla K80) actually works and is highly profitable”, no,
Mining on these GPUs is simply not a profitable business.
BCN mining on the K80 is about 126 H/s per GPU. ($12/month at the current price/difficulty)
ETH mining on the K80 is about 6.5Mh/s (CUDA Mining)
ETH mining on the K80 is about 7.1Mh/s (OpenGL Mining)
ETH / Sia coin mines roughly 7.1 and 71.8 MH/s (respectively, via Claymore Dual Eth Miner)
