Test Results: Ethereum Hash Rate
In the chart downpage, we compare the performance of all GPUs in Ethereum mining, measured by hash rate in MH/s (million hashes per second). We use Claymore's Dual Ethereum AMD+Nvidia GPU Miner in "-benchmark" mode, specifying a DAG epoch of 190, buying us a bit of time before that epoch comes and goes.
Bear in mind that these hash-rate results should be considered alongside our power-consumption numbers. Besides higher energy bills, power-hungry GPUs are also more difficult to cool.
That is a key point to keep in mind from a card-longevity standpoint, too. If you have multiple high-wattage cards crammed into a poorly ventilated space, their reliability could be severely affected. Lower power consumption reduces thermal load, making it so that you have to worry less about the temperatures of your precious graphics cards.
During all measurements, we keep a steady temperature of around 70°F (21.1°C) and a humidity level close to 35%. For now, we have Nvidia's Pascal-based cards tested at their default clock rates. But we plan to add AMD's current-generation products soon, along with configurations optimized for mining.
Nvidia's Ethereum mining performance king is the GeForce GTX 1080 Ti, with the company's much-more-expensive Titan Xp following closely. The GTX 1070 Founders Edition takes the lead from MSI's 1070 Ti, while both GeForce GTX 1080s that we tested are left way behind due to their GDDR5X memory and its inferior timings. Finally, the GTX 1060 with 6GB of memory (the 3GB wouldn't run under DAG epoch 190) fares pretty well, given its price.
A relative chart depicts the differences in performance between our test subjects in a more straightforward way. The GeForce GTX 1080 Ti Founders Edition is our reference (100%), since it achieves the highest hash rate.
