AMD Radeon RX Vega 64 and Vega 56 Ethereum Mining Performance

The AMD Radeon RX Vega 64 and Radeon RX Vega 56 Graphics cards are out now and hopefully you’ve taken a look at gaming performance in our full review of both those cards. There have been rumors that the AMD Radeon RX Vega 64 is capable of getting hash rates as high as 100 MH/s mining Ethereum, so we also spent come time with Vega 64 and Vega 56 down in the Ether mine to see how they’d perform.

AMD Radeon RX VEGA 64

We used Claymore’s Dual Ethereum AMD+NVIDIA GPU Miner v9.8 and tested the two VEGA cards one at a time in the system to see how they did on the current DAG epoch #138. We also tossed in an NVIDIA GeForce GTX 1070 video card from a board partner just for fun as that is one of the most popular mining card that people can buy today with most Radeon RX 570 and 580 cards being out of stock.

AMD Radeon RX Vega 64 Ethereum Hashrate

So, on the current DAG Epoch (#138), difficulty of around 1,700 TH and a block time of ~21.5 seconds this is what we are looking at in stock form with 1 minute average after running for a period of 15 minutes to let the cards warm up. The AMD Radeon VEGA 64 gets 34.4 MH/s with the system pulling 367 Watts at the wall. The AMD Radeon RX Vega 56 gets 32.4 MH/s with 306 Watts at the wall. Not bad results, but not close to the rumored 70-100 MH/s performance these cards were said to have.

Vega 64 Hashrate Power

No sane miner uses stock settings, so let’s look at what happens when we overclock the cards and use some power saving settings. The AMD Radeon RX Vega 64 was able to have the power limit lowered to -30% without drastically impacting the hashrate of the card as it was 34.3 MH/s, but our power dropped down to 283 Watts. We dropped it down to -25% and for 33.9 MH/s at 269 Watts and then finally -40% and got 32.6 MH/s at 256 Watts. Lowering the power target really helped the power consumption as going to -30% saves about 84 Watts and that is a ton if you have a mining farm with dozens of cards that is consuming thousands of Watts of power all day for months on end. Overclocking the memory didn’t change performance on either card. This might be a driver issue, but right now this was the best we could get.

The AMD Radeon RX Vega 56 we were able to drop down to -25% and we got 247 Watts at the wall, but the hashrate took a dive to 30.1 MH/s. We ended up dialing it in at -23% for a hashrate of 32.40 at 251 Watts.

Lastly, the GeForce GTX 1070 was able to be overclocked with EVGA Precision X up to +800 MHz memory. With the extra memory clock speed and  we got that card up to 32.17 MH/s! We also did that with the power target lowered to 60%, so the power draw dropped down 183 Watts despite the memory overclock!

Hashrate per watt

So, what else can we show you? How about hashes per Watt? The NVIDIA GeForce GTX 1070 that has had the power target lowered offers the best hashrate per Watt and that is critical for your electric bill. In stock form the AMD Radeon RX Vega 64 gets 0.09 MH/s per Watt of power used and we were able to improve that to 0.13 MH/s per Watt on both the Vega 64 and Vega 56. That is where a GeForce GTX 1070 is stock.

The AMD Radeon RX VEGA 64 was going to be a hit for ethereum mining, but it looks like performance just isn’t where it was rumored to be. AMD has stated that they are working on a block chain driver that improves the DAG performance for all Polaris and Vega cards that should be out sometime really soon. It will be interesting if the optimizations fix the DAG performance drop that has been coming for months and improves Vega performance. We will know shortly and coverage will be posted on Legit Reviews the day it drops. When we requested more cryptocurrency performance information our contacts at AMD said they were focused on gamers and had nothing to add. We are sure that the mining community will try these cards out and modify the firmware to extract the most performance from VEGA in the coming weeks. This might not be a mining monster that everyone read about for the past few weeks, but it isn’t a turd either.

When it comes to pricing the AMD Radeon RX Vega 56 is $399 and the Radeon RX Vega 64 is $499 for the standalone air cooled models. The MSRP on a GeForce GTX 1070 is $379. Chances are you won’t be able to find any of these cards for those prices due to the mining boom, but they are more readily available now than they were a couple months ago. The ASUS GeForce GTX 1070 8GB STRIX will be in stock on August 18th for $449.99 and the Gigabyte AORUS GTX 1070 8GB will be on the same date for $439.99. It will be interesting to see what the AMD Radeon RX Vega cards will be priced on the street later today.

Update 08/14/17 1:30PM CDT: VEGA 56 Overclocked! 

We have been playing around with overclocking a bit more on the VEGA RX 56 and the performance numbers are a little weird. We are able to overclock the memory from 800MHz up to 950MHz with full stability. Running the memory at 1000MHz causes an instant crash and 975MHz causes random crashes at load, so we stuck with 950MHz. The Vega 56 gets 38 MH/s when we start mining, but down to an average 1 minute speed of 34.17 MH/s after just six minutes of mining. This is a nice bump up from the stock number of 32.43, but we wish it would stay up at 38 MH/s. We were doing this run with the power limit at -23% and when we raised that up to -10% the 1 minute average increased up to 34.1 MH/s. The power jumped from ~252 Watts to over 320 Watts by doing that. We are still investigating and let AMD know of the issue as no matter the power limit performance starts out at 38 MH/s and drops down 3-4 MH/s after a few minutes. We also have been having issues with Wattman going transparent during use, so another growing pain that needs to be worked out on Vega!

Update 08/15/17 8:00AM CDT: Stock VEGA 56 w/ NiceHash Miner Beta Standard Benchmark!

 Update 08/15/17 12:00PM CDT:

AMD has released a mining optimized driver for block chain workloads this morning and we have tested that driver in our most recent article.

  • Aaron Morrow

    A quick comment on the HBM overclock that increases hashrate to 38, and then slows down over time: this is likely due to the HBM overheating. The fan speed is based on the core temp, but the HBM gets hotter than the core when mining AND overclocked. Either swap the paste, or ramp the fan speed up.

  • Samuel Burg

    drop of speed after several minutes is due to HBM thermal throttling.

    so, you need to lower HBM voltage to 900mV, and you have to increase fan speed. then perf will be stable.

  • Mark Lepore

    These comments are so mis informing. Vega56 hashes at 38mh when the Dag is set lower then #140 and goes back down to 32mh once dag epoc #145 kicks in. It has nothing to do with memory clocks. Both Vega and Polaris have this issue with larger Dag files lowering the hashrates.

  • Jozef Mikula SkiFi

    investing in mining today will probably not get back or? The difficulty increases so fast the a prediction of a setup to earn 800 a month will drop to like + 50 a month in just only 3-5 month making it almost zero after 6 months … thus you will be happy to earn your costs back …

    I only too an article 3 months old with a seput to earn 150 a day which today would only earn about 20 making it red number in a month or two …

  • Bog

    Here are my settings and hashrates (36.9 ETH/2000 DCR sustained) for a Powercooler VEGA 56 flashed to 64 bios:

  • david israel

    are you all crazy? why on earth will any miner buy this F card????
    you can get for the same price 3 1060s (in stock) and they will do 70 mhs (50% more!) with less power on all 3!!!!

  • HamsterNet

    This is some really poor results. been testing my Vega 64 with the following:
    Vega 64, Core +5%, Vcore 1050, power +50%, mem 1100. Core hold steady at 1712mzh.
    Gives 44Mhas continuously using Claymore. Was getting 36 but only on total stock, with the core speed bouncing all over the shop..

  • Clement Wong Kin Sung

    i pay 6 US cent per kilowatt hour, that extra production is worth that few cents per day……if i’m stupid enough to mine with Vega. my RX 550(2)+560(1) mining rig can do almost just as well at 32mh/s.

  • Illutian Kade

    It’d be smarter to just spend the money buying Ether/BTC/LTC straight up, instead of mining it.

    Use a Trading Bot and enjoy the ride.

    • Abdelhaq

      What trading bot is any good out there??

  • Mark Lepore

    38mH/s is nice for the Vega 56… if you want it to stay at 38… I am guessing it is heat related and is starting to throttle.

  • Foxy

    Guys if I may be so bold to add: My friends company make sound dampened, filtered home miners for Altcoin mining using 1060´s and the performance to watt ratio and resale value seems a much better deal to me… ( especially if I don´t have to deal with noise and dust and building it myself in my home… 😛

    (Shameless plug end.)

  • Joeyjoejoeshabadooo

    for us part time gamers part time miners?how does this affect gaming performance

  • nvooser

    1070 MH/watt !!! Never realized how much ahead these cards are.

  • TheXev

    I’ll hold my judgement until after Claymore has one of these puppies in hand to optimize.

    I’m still going to buy one though (because my goal is always to have my last video card pay for my new one, and with Vega that will make the chain four deep [5700=>R9 290=>3x RX 580=>RX Vega 54??), I really want a AIB cooler.

    • Nathan Kirsch

      I’m pretty sure he has one seeing how he needed to release v9.8 with Vega support before it came out. He likely needed a card for that or AMD told him what needed to be done for Vega support. He also had the DAG improvement driver weeks ago as he confirmed it worked and was coming. I’m sure he’s working with AMD as the six quarters of consecutive growth is due to mining to some degree.

      • TheXev

        I wonder if this has something to do with the SDK version mismatch of 17.7.2 (this driver caused issues with stuff like Afterburner, and the devs couldn’t fix OCing because the SDK hadn’t been updated I can’t even run this driver with my 3x RX 580 config!)?

        I have to wonder if this driver you’ve talked about enables the additional instructions for mining that AMD has talked about in OpenCL? Perhaps the additional SDK changes were held back because of it as well? Hmmmmmmm. (I honestly can’t wait for this driver now! )

        • Nathan Kirsch

          Report back how it goes! Just remember this is an older build, but should give you a taste of what it coming. The leaked version worked on my cards. DAG #138 had the same performance as DAG #199 and overall performance was a bit better on my 480/580 rigs.

  • Dai Hoc Ngoai Thuong Khoa Quoc

    i want to punch the idiot that say it can get to 70 to 100mhs waste of my precious time

  • Łukasz Lis

    Oh. that’s very good. thats veeeryyy good. There will be some VEGAs left for us, unworthy gamers… ;/

    • Juan Ballesteros

      why do you want a toaster for playing? Right now you can take better cards, with better price, and ofc better power consumption

      • kelthar

        Don’t care abouyt energy consumption. Which card has a better price and performance? From my point of view, 56 seems like a much better deal than 1070.

        • Nathaniel Lewis

          From a gaming perspective (as in power draw isn’t an issue) the Vega 56 should be the highlight of this whole release. Assuming that it can be had for the introductory price, it’s selling cheaper than most 1070s are, while having a respectable performance gain over it. The Vega 64 wins and looses some to the 1080 while having the same (or greater for the liquid edition) pricetag.

        • kelthar

          56 can be undervolted and overclocked to gain a lot and there has been a lot of talk that some of their features for these are yet to be implemented in the drivers, but time will tell. AMD has a history of having really bad drivers on launch and their card gaining performance over the coming months / year. I think that there’s a strong possibility for that in this generation, however, nothing is guaranteed. It’s a pity they don’t have enough funds to have them on release date. I don’t know if 64 can benefti from undervolting, but I have done this myself with the 480 and it gave me a significant boost and stabilization of FPS. They are playing too safe with their voltages.

        • Andrew Karassik

          What overclocking software would you recommend for the 480?

        • Clement Wong Kin Sung

          i’m doing GTX 1080, superior price, performance, power consumption and mining income, bought it at 600$, while vega 64 costs 900$ in my country.

    • Matthaus Woolard

      Expect mining code to be optimised more as time goes on

  • José Manuel Varela

    I would like to see the article or news from which they extracted the following information:
    “AMD has stated that they are working on a block chain driver that improves the DAG performance for all Polaris and Vega cards that should be out sometime really soon”

    • Antonio Amigo

      They said it so now article is required.

    • Nathan Kirsch

      You can source me… I’ve owned LR for 15 years and have worked with AMD on pretty much every desktop launch since there. The day the block chain driver comes out officially you’ll see it here on LR. There was a leaked version out making rounds last week, so it is the real deal.

      • Juan Ballesteros

        i can trust you but there is a lot of (my) money on bet, because i just bought 5 gpus (thats a lot for me) expecting 50 mh/s on etherum, at least, and now i have some time to cancel the operation… What do you sugest?

        • Nathan Kirsch

          The highly anticipated block chain driver is expected to improve the decreasing performance issue from the ever increasing DAG epoch size. It’s aimed at Polaris and Vega cards and not older 200 or 300 series cards. AMD is focused mainly on gaming performance with VEGA and getting the drivers to work properly for that community right now. With overclocking, modified vBIOS and driver improvements I think these cards can get improvements. Heck, overclocked the Vega 56 shows 38 MH/s for the first dozen seconds and then trails off down to 34 MH/s. If AMD can find out why that is happening and fix it and make said improvements I can see positive improvement coming. Just don’t mix up a DAG improvement driver with a Vega performance boost driver.

          Oh and just so you know I have a half dozen systems running about 30 GPUs, so I get you. I saw the rumors just like you. I’d give it a few weeks with the cards and see where it ends up. This is just the beginning.

        • Juan Ballesteros

          Thank you very much for your fast reply. I will wait. And pray. Haha

        • Nathan Kirsch

          The official driver is out and linked in my latest article –

      • Hai Diep

        What’s the impact on r9 fuey

      • José Manuel Varela

        How long do they wait for the controller to arrive?

  • Josué Tds

    please, test in Zcash

    • Bakes

      Yes Please!

  • Saul

    This is a bummer. Anyways RX Vega 64 is sold out. Seems like people went crazy expecting 70-100 MH/s per card.

    • bt1234yt

      Give it a couple of week, then there will be dozens on Vega cards on EBay once miners find out that the 70-100 MH/s rumors aren’t true, and their power bills go through the roof when they try to mod the cards to reach those hash rates (I will award bonus points if Etherium has another price crash in the next few weeks or months).

      • Kacper Strzemieczny

        i think that it will be 100mh/s once they omd the card so badly that it wil be only able to mine(coustom bios that is optymalised for mining)

  • Thomas Wolf Tompkins

    300 to 350 watts but how much money you making per day running a 24 hour period.

    • Nathan Kirsch

      A stock Radeon RX Vega 64 will make 0.25 Ether ($75.09) with a power cost of $36.99 and a profit cost of $38.07 per month. Based off current difficulties, driver, Ether at $295, a power cost of $0.14 and so on. That number decreases daily, so that is the best case. With Vega 64 at 34.30MH/s and 283W that card will bring in the same 0.25 Ether, but you get $28.53 in power bills and $46.05 in profit. So, optimizing the card will make about $8 more profit per month per card mining. You can do this all yourself here –

      • Thomas Wolf Tompkins

        38 a month yep glad I’m not doing that my Antminer L3+’s are making around 4500 a month minus power costs

        • Nathan Kirsch

          How much did your Litecoin miners cost? Saw something online for $1,400 and them on Amazon someone is asking $4,995 for an AntMiner L3+ 504 MH/s Litecoin miner.

        • Thomas Wolf Tompkins

          1200 each right from bitmain themselfs batch #2

        • Andreas Vetter

          How many do you have mate?

        • Thomas Wolf Tompkins

          2 of them

        • Spuros Miltiadous

          Thomas could you explain please what are you minning exactly? you use nicehash miner auto?

        • David Neff

          Thomas, what are you mining? BTC?

        • Thomas Wolf Tompkins

          about 0.02 to 0.04 a day at current prices. SInce I got them im at 0.25 BTC

        • KinderSurpriseTube

          How can you mine 4.5k with 2 L3+? At current difficulty/ltc price, it is about 1.6k @1010MH/s

        • Thomas Wolf Tompkins

          Because I don’t mine just litecoin. Some coins worth a lot more then LTC.

        • Thomas Wolf Tompkins

          I mine NiceHash Script which auto switches

        • KinderSurpriseTube

          Are you minimg BTC with L3+ ‘s or are you using other miners besides those two?

        • Thomas Wolf Tompkins

          Just the two also its 4.5k CAD. Since Im in canada.

      • TheXev

        Well, this driver it works (I installed it by copying over my 17.7.2 driver folder and running the installer after DDU). I suppose if I had a larger mining rig with more constant OCing (I have one card I cannot OC the RAM on, it just errors to hell and back if I do), but my 3x XFX CBR 580 8GB setup has gone from 80-81Mh/s to just below 82Mh/s. I’ll have to see if my effective hashrate to nicehash (that’s how I mine) returns, as its been peaking and dipping way more then it used to.

        • Nathan Kirsch

          Should be about 1 MH/s per card ‘restored’ from what I saw on the leaked driver on my overclocked 580’s. The magic is down the road the performance doesn’t drop with the larger DAG sizes.

        • Asif Jawed

          Hey nathan,
          Could you explain how does this auto switch thing works as i am new to mining and want to know about it?

          And is it really true that you can increase your predictability by using auto switching software?

          I would appreciate it of you could help. Reply either here or on my email


      • matt

        What’s the point? $38 a month in “profits” except you don’t factor in wear/tear on the cards and computer components and the extra cost to cool your house as these things are going to be space heaters. We are talking under $30 a month, and at least a year to return on your investment of just the GPU alone. So fucking stupid. One power supply death and you are out another years profits.

        Just go to work for an extra few hours a month, or go mow someones lawn. Jesus.

        • Nathan Kirsch

          I used to think the same thing, but you are forgetting a couple things. The video card will have value at the end, so that needs to be kept in mind on the return on the GPU investment. There is also the chance that ether goes up in value. It has gone up over 3,000% this year alone and some are predicting that it hits $1,000 in 2019 (source: That bullish market is what is driving so many to mine right now. Sure at $300 a share you are only making $38 a month, but if you hold Ether for the investment in it and it goes to $1000… All of a sudden that $38 you made in 2017 may be work $217 in 2017. That is why some people are mining with dozens or thousands of cards. Some are selling and exchanging into FIAT right away, but others HODL!

          Lastly, keep in mind that Ether Mining is huge in Asia and in many developing countries the average person makes under $500 a month. Mining even an extra $40 a month can make a huge difference for people in that situation.

          Edit, I just looked and the average yearly wage in China is 67,569 CNY or $10,120 for 2016. That means the average person in china makes just under $850 per month. Just to put the dollars into perspective.

        • Ruud Niet

          Value a miner card … you mean being dishonest to people selling the card as new ….

        • Wacky Tobaccy

          No. You sell the card either as used, or as a refurb after it blows up. These cards have a 2-5 year warranty depending on the brand. I bought a refurb from a miner for cheap. It died in a few months. Replaced under warranty with a brand new card. Win-win.

    :/ Vega 64 and 34MH/s waste of space ,
