AMD Radeon RX Vega graphics cards do very well on the CryptoNight proof-of-work algorithm and miners are using them to mine Monero, Electroneum, Sumokoin, Bytecoin and Karbo. This is because the profitability is better on those coins than Ethereum that uses the Ethash proof-of-work algorithm. It’s tough to find an AMD Radeon RX Vega 64 or AMD Radeon RX Vega 56 graphics card due to this. You might get lucky and find some in-stock at Amazon or Newegg, but it is tough. If you switch tactics and look for used AMD Radeon RX Vega 64 cards on eBay you’ll quickly find that they are selling for well over $900.
Paying close to $1,000 for a new or used AMD Radeon RX Vega 64 is crazy considering you could pick one up for just under $570 direct from Amazon in November 2017. What is the mining alternative to the AMD Radeon RX Vega 64 and Vega 56 cards?
Meet the AMD Radeon Vega Frontier Edition (product page). This card was introduced back in June 2017 for $999 and was targeted at data scientists, immersion engineers, and product designers rather than gamers. AMD must be sitting on a pile of Radeon Vega Frontier Edition graphics cards that they are trying to move as they recently started marketing the card for “blockchain pioneers’ and the street pricing has been slashed to $749.99 shipped at places like Newegg to possibly get them moving. That doesn’t bode well for resale value, but it should be worth mentioning that these cards are in-stock at $749. They have 64 compute units with 4,096 stream processors clocking at up to 1600 MHz and are loaded up with 16GB of HBM2 memory that has 483 GBps of memory bandwidth at stock speeds. They overclock just like the Radeon RX Vega 64 cards, so you can take that 16GB of HBM2 memory up to the 1050-1100 MHz range on most cards and get over 2000 H/s per card like a Vega 64.
We gave up trying to get several AMD Radeon RX Vega 64 cards and managed to get three AMD Radeon Frontier Edition cards and slapped them onto a test system. Our system consists of the following hardware:
After fighting the cards a bit we managed to get all three cards working with pretty good stability and are getting 6,165 H/s on the XMR-STAK-AMD mining utility by overclocking the cards memory up to 1100 MHz at 930 mV. This puts us at roughly 2,055 H/s per Vega Frontier Edition card, which is excellent. Total system power draw at the wall is around 660 Watts with these settings. We are still tweaking this setup to make it more efficient. Right now we are doing a 24-hour mining test with the P7 core clock at 940 mV and that drops the overall system power down to roughly 620 Watts and the total hashrate to 6,145 H/s.
According to the Monero Mining Profit Calculator over at MyCryptoBuddy this setup will make $15.92 per day and after electric costs ($0.10 per kWh) we are looking at a profit of $14.34 per day. Last month when the difficulty was half of what it is now you would have been making around $32 per day in profit. The difficulty is going up, but hopefully the price of XMR will increase to help keep the profits per day up to where miners will be happy. Some Monero price prediction sites are showing that Monero will top $900 in 2018 and $3000 in 2020. We don’t have a crystal ball to know where the price of XMR Monero is going, but if those predictions come close to being right it will make many miners extremely happy.
Hopefully this article helps those that are looking to buy and AMD Radeon RX Vega series card to mine with. Please don’t pay insane prices for AMD Radeon RX Vega 64 or Vega 56 cards when you can purchase the AMD Radeon Vega Frontier Edition for $749.99 shipped. We’d much rather own the Vega FE at $749 versus a used Vega 64 Air Cooled card for $920+ dollars. The ideal situation would be to find a Vega 64 or Vega 56 card for under $600 like they were back in November 2017. Mining with Vega FE cards is pretty tricky and are best done in a dedicated mining system due to the setup complexity. These cards are great for mining, but they aren’t for the gamer that is interested in mining in their spare time due to the fact that you have to run six month old blockchain drivers among other things. That said, I’m tempted to pick up some risers and a couple more cards with the hopes of getting 10,000 H/s from this system!
We will end this with some tips for those that actually run out and purchase AMD Radeon Vega FE cards to mine with!
Setting up a single AMD Radeon Vega FE to mine is simple, but setting up more than one of them to mine was a bit tricky. Here is what we learned over the course of a week to get multiple AMD Radeon Vega FE graphics cards together on one platform.
