RX Vega Achieves 43 MH/s @ 130 W in Ethereum Mining
AMD's RX Vega is more along the lines of an original computing card that was moved over to the consumer segment for gaming workloads than the other way around. Raja Koduri himself has said something along those lines (extrapolating a little more than what he can actually say), and that much can be gleaned with at least a modicum of confidence through AMD's market positioning and overall computing push. In the argument between gamers and miners, Raja Koduri didn't have all that much to say, but for AMD, a sale is a sale, and it would seem that after some tweaking, RX Vega graphics cards can achieve much increased levels of mining efficiency than their Polaris counterparts, further showing how Vega handles compute workloads much better - and more efficiently - than traditional gaming ones.
Now granted, Vega's strength in mining tasks - Ethereum in particular - stems mainly from the card's usage of HBM2 memory, as well as a wide architecture with its 4096 stream processors. By setting the core clocks to 1000 MHz, the HBM2 memory clock at 1100 MHz, and power target at -24%, Reddit user S1L3N7_D3A7H was able to leverage Vega's strengths in Ethereum's PoW (Proof of Work) algorithm, achieving 43 MH/s with just 130 W of power (104 W of these for the core alone.) For comparison, tweaked RX 580 graphics cards usually deliver around 30 MH/s with 75 W core power, which amounts to around 115 W power draw per card. So Vega is achieving 43% more hash rate with a meager 13% increase in power consumption - a worthy trade-off if miners have ever seen one. This means that Vega 64 beats RX 580 cards in single node hashrate density, meaning that miners can pack more of these cards in a single system for a denser configuration with much increased performance over a similarly specced RX 580-based mining station. This was even achieved without AMD's special-purpose Beta mining driver, which has seen reports of graphical corruption and instability - the scenario could improve for miners even more with a stable release.
Moreover, S1L3N7_D3A7H said he could probably achieve the same mining efficiency on a Vega 56, which isn't all that unbelievable - memory throughput is king in Ethereum mining, so HBm2 could still be leveraged in that graphics card. It seems that at least some of that initial Vega 64 stock went into some miner's hands, as expected. And with these news, I think we'd be forgiven for holding out to our hats in the expectation of increased Vega stock (at the original $499 for Vega 64 and $399 for Vega 56 MSRP) come October. Should the users' claims about RX Vega 56 efficiency be verified, and coeteris paribus in the mining algorithms landscape for the foreseeable future, then we can very much wait for respectable inventory until Navi enters the scene.

Were on about mining efficiency bullshit in this thread man ,get with the flow, just sounding like a butt hurt hater who woke up the wrong side of his bed, i do it myself sometimes.:)
It's going to be different for everyone if the power savings would be enough to offset that, since power rates fluctuate so much. It's 6.5 cents kw/h in my area, but other areas are up to double that. And it still would take quite a while to make up the higher per MH card cost than a 580 in 15w an hour less power.
But it's all kind of moot until you can actually buy the cards for retail, since it's really going to be very tough to recoup costs at gouging prices. And there's the roll of the dice that ether prices won't crash again, and that difficulty doesn't shoot through the roof more than it has, and that ether doesn't go proof-of-stake before you earn your $ back. A year ago that was expected this past summer, so we're already kind of in bonus time for proof-of-stake.
I don't think Amd aimed at mining its a result of trying to catch-up with nvidias gpgpu offerings as its clear Ai will be big in the future.
Your first comment"So many butthurt AMD employees on TPU now. Here's a pro tip. Build better products, hire a better marketing team, don't lie about price to reviewers. Believe it or not people can do math and hedging you bets with miners is a losing one."
Just decries Amds pr and pricing , nothing to do with mining efficiency imho
And with the tone you show again in a thread plus avatar ,sure seams like you have a chip on your shoulder and are leaning fanboi style yourself.
Amd fogot to send my pay check for the last 15 years where do I complain.;):)
I really doubt AMD hires any fanboys. They don't have the money to do so.
:pI was thinking of miners picking up your used vega. I've seen people sell their used R9 290s from gaming rigs for 30-40% more than they're worth during the holidays.
It's purpose is cryptographic comparisons.
There really isn't a tap dance.
Just wondering what mining software you're using withe the Vega's?
I can't seem to get my Claymore Miner to read the Vega's at all. It works fine with the 570 and 580's (and all the nVidia's) but cannot recognize the Vega Cards.
Any help would be awesome.
Main issue with AMD is that their GPUs are nowhere to buy for reasonable price, not that they don't perform well.
It's sad but the only way AMD can recover is by doing exactly the same things that we hate Nvidia for doing. In reality it never really mattered if they had faster and cheaper cards because review sites always found vague and ridiculous reasons to not recommend their cards. Just look at reviews of the 290X and RX480.Sorry to say this , but you don't really know what you are talking about.
i think, yes
Do you think energyefficiency matters when talking about gaming?
i think yes, if you don´t have electricyty for free
i think yes, if you want to easily and quiet cool your rig
Do you think there is a factor "x" in per clock-performance, when comparing nvidia GPU-Cores to AMD GPU-Cores?
i think the upper limit is about 1:1.25 to 1:1.33 advantage per clock at nvidia in average in games
this is btw one big point in the efficiency, just compare the Watt, Performance and Efficiency etc. of the 2048 Core Cards: GTX980 with the RX470, RX570
and additionally the GTX1070 with 1920 Cores.
maybe you learn a bit
My only comment to you was and I quote :I wasn't arguing about anything , it was just an observation.
