As you can guess from the title, I've made a benchmark list for Equihash. I've gathered info from bitcointalk and the Zcash/Zclassic chats/forums. The list is not yet complete (it will most likely never be since the miners get updated so often and plenty of new cards are coming up this year).

Much of the data is being hard to get without first hand experience but I managed to gather some, this is the list at the moment: https://zdeveloper.org/wiki:zcash_mining_benchmarks
I'm waiting for corrections and updates. Maybe it will helps some people decide which cards to get next time they assemble a rig.  Smiley

Most power efficient (Sol/Joule) cards:

AMD        RX480   Sapphire Nitro+ OC   8GB   305/140 = 2.2
NVIDIA    GTX 1070   -                           8GB   450/100 = 4.5

Shockingly, Nvidia is more than twice as efficient...


Nvidia truly beats AMD when it comes to mining Zcash, but lacks efficiency in Monero and Ethereum (except for those special cases where people have developed some very efficient but private Nvidia miners).

NVIDIA    GTX 1070   -                           8GB   450/100 = 4.5  With these settings it's more like 140-150W. I have 2 x 1070GTX and with -150 CORE and 70% POWER LIMIT I have about 110W/card @ 385sols/s.

Even 385/110 = 3.5 J/W. That is still more efficient than the AMD cards.

Is that power number from the wall?

You can get about 420 sols @ 105W from the wall (i have couple of brands of 1070 and this applies to all of them, do not have 8+6pins though). Both of these comments are innacurate. Firstly you cannot get 450 sols at 100w with ANY 1070. Secondly it is bad underclocking the core for equihash algos.

I'm getting around 140 sols @ 65W on 1050ti.    However if you include the computer it is running closer to 75W. 

140 sols / 75W ==> 1.87 sols / W  ... not that great.   

It can probably be optimized a bit more but for equihash the 1070 is beating it hands down, more the double the efficiency.
