Vega has better hashrate than 2 580s.

The most important thing people often keep omitting from posts like this is that Vega is ONLY faster than two 580s on cryptonight. This is not the case for every other algo out there. The most popular of which is (and has been for more than a year now) ETH/Dagger. Two 580s will do close to 60 MH/s while one Vega will be doing up to 45 MH/s.

Cryptonight profits might (and probably will) go down at some point. It has happened before, there were periods when XMR was the most profitable coin for AMD cards, but then it would go down and ETH was pretty much the only option available for months. Suggestion to go with single Vega against two RX 580s just because cryptonight has been so profitable lately is pretty shortsighted in my opinion.

Vega has better hashrate than 2 580s. Vega also has lower power consumption than 2 580s. The only thing I see as advantage of 580 is when a card fails, you will still be able to mine with the other 1. Also I don't know the availability between 2 gpus but profit, price and power consumption in consideration, choose Vega.

Thank you your reason for the RX 580 speaks makes sense, I had already considered. The only question is how it behaves when I underclock all cards ..I usually underclock them to about 800Mhz. for example 800/1500

My Question:

One RX Vega 56 / 64

OR

Two XFX Radeon RX 580 GTS XXX Edition 8GB GDDR5

What u guys mean? Which of both have better performance?

this is an alt coin question.

a vega 56 done correctly is better but I don't own these cards

Here is a huge thread with info for you

Thanks for the link. Would the Vega 56 already be better than two RX 580 or would it already have to be the Vega 64? I ask because there is a price difference of $ 120.

There are a lot of factors to consider when choosing the right GPU for you. Do you already have a built out rig? What is your PSU max consumption? Are electricity costs expensive at your location? Do you plan to expand and buy more GPUs in the near future? Building a profitable mining rig needs to be planned out to very specific details.

If you are looking to get the most efficient GPU in terms of hash rate / power consumption then i suggest getting the VEGA. Mine hashes 1900h/s cryptonight at only 130watts.

Thank you for your answer. Basically I do not want to mine ETH but rather cryptonight and some ethhash coins. At the moment I use only 2 strong PC systems but a rig is planned later with several GPUs. The power costs are not low for me, but I underclocke my GPUs in principle, my current RX 580 consumed, for example, currently under load only 70 watts.

RX 580 makes about 750 h/s and x 2 this is 1500 h/s in Monero. 1 x RX Vega 56 makes 1750 h/s in Monero , power consumption is better and lower with only one card so the equation solution is pretty simple. 1 x RX Vega 56 is better than 2 x RX 580 cards, at least in Monero. Haven't had the pleasure to work with RX Vega 56 yet (I will after 1.5 week when I will build a 8 x RX Vega mining rig in ASUS mining expert board).
