Some days ago I startet a comparison and now I want share the result with you.

Configuration

For the comparison I have used four rigs: two mining on Ethermine and two mining on Nanopool. They all have the same hardware and software configuration. One rig has a hasing power of ~193 MH/s. Here are the details:

Hardware

• Motherboard: ROG STRIX Z370-F GAMING
• CPU: Intel i3-8100 @ 3.6 GHz
• 5 x GeForce GTX 1070
• 2 x GeForce GTX 1060 6 GB

Software

• EthOS 1.2.9
• Ethermine 0.14.0.dev2

Config

# global settings
globalminer ethminer
globalmem +470
globalcore 1500
globalpowertune 120
globalfan 90

# rig settings (replace xxxxxx with rig id)
# GPU order: 1070 1070 1060 1060 1070 1070 1070

mem xxxxxx 4270 4270 4650 4650 4270 4270 4270

Comparison

I started all the miners on 2018-04-03 at 20:00 until they reached 0.2 ETH. The result is represented in the next picture:

The difference is very small. Facts:

• Nanopool reports more (~6.8%) hashing rate than Ethermine.
• Nanopool seems to be faster (~2.5%) in the first 24 hours of mining.
• Ethermine reached 0.2 ETH in 6 days 15 hours and 42 minutes. Nanopool reached 0.2 ETH in 6 days 17 hours and 33 minutes. Ethermine is performing ~1.15% better!

Raw data

Conclusion

Ethermine is performing better, so I would choose it Please leave a comment if you have done also some tests. It would be nice to compare other results.
