Evening.

I have done some testing the past few days with a Nano and i want to share my findings.


First picture is a picture of the power usage of the system without a gpu installed.

So 43watt when running idle (i7 processor with 32GB Ram, Win10Pro 64bit)


Next picture is a screenshot of the Nano running Ethereum.

Stock clocks (1000/500) @ 26Mhz average.

Power draw

102 watt give or take for the Nano running Ethereum @ 26Mhz


Than we have a screenshot of the Nano running X11 (not the newest Nicehash optimized miner)

Again Stock clocks @ 12Mhz average + not even playing with intensity, XI 1024 would have given me probably more.

Power draw

105 watt for the Nano @ X11


Next one is Quark, again, not the newest Nicehash optimized miner.

Stock clocks @ 16Mhz, a little disappointed here..

Power draw is almost identical to Ethereum power draw.


So my conclusion.

Best card i have ever had, Period!

There's no Nvidia card that can beat these numbers (yet).

Although, as mentioned before. It's an expensive card.
But worth every penny and it looks better too!  8)

Yeah, i'm an AMD Fanboy, i know :p

If there are questions or if someone wants to see another test, just ask.

Amazing numbers. What is the clock per clock (and watt per watt) performance nano vs fury vs fury x?

Here are some old tests i've done with some Fury X's

https://bitcointalk.org/index.php?topic=1116027.msg11950487#msg11950487

Last red card I had was 6990 so I dont know what is going on there. Is it possible to run fury x limiting power usage to nano levels?

Ethereum, nano vs fury x, same watts at the wall? What is the hashrate then?

Haven't done an exact power measurement for a Fury X on Ethereum but i know it hits 27Mhz stock clocks and i believe plus minus 200 watt, i would need to test that to be sure.

For Quark, you need not memory speed, so it can be reduced to much lower value, so will the power draw.

I don't think you can change the ram speed on Fiji chips.
Maybe with some bios hacks...

So some energy will be wasted. When I run Quark, I just use 260MHz instead of 1500 MHz for memory. There is no effect on the mining speed.

how long its gonna break even though.
Dear god the price is crazy.

The Fury cards are not meant to be used for mining. The price is too high and they are not efficient (price wise) in Ethereum mining. The best for Ethereum is 280x.

@Eliovp

I'm not meaning to come off as a troll but you admitted you're an AMD fan boy so it's fair game to challenge you.

"best card ever"?

The numbers you posted put it on par with the GTX980 but at a much higher price. Considering the 980 is 1 1/2 years old,
and second in line, that isn't much to brag about. Will you be testing with the new miner? That might look more impressive.

What is already impressive with the nano is the size reduction, packing 980 performance in a half length card is
an achievement. But that raises the issue of heat dissipation, always a concern with AMD. The improved power
efficiency is nice to see but AMD is still playing catch up.

With the expectations of pascal in the next few months nvidia will probably jump ahead again.

If AMD wants to really compete with Nvidia they either have to put out a better product, or a cheaper product.
An equal product at a higher price won't do it.

Okay, lets say it like this: True i'm in a way an AMD fanboy. I always support the smaller players. I still support Nokia :p (nah i'm joking..)

Yes, for me, best card i ever had. Not only because it's so energy efficient, but also because it's so small, it stays cool, it wouldn't go higher than 65 degrees with fan speed at 25% or so when i was testing (must admit, it wasn't inside a case, still isn't and in an open warehouse), so the heat issue isn't even there. Plus it isn't "that" expensive.

How much did the 980 cost when it came out? And how much does it still cost?

I totally agree with you regarding the price, although that i made a few deals and it's a lot cheaper on my part. But in general, true, it isn't..

The "an equal product at a higher price" statement, that's something i surely don't agree on.

It's in my eyes in no way equal to anything Nvidia offers. The size alone... Temperature you spoke about. I'm now running it at core clock 1100 and it's at 70 degrees (fan @ 40%). Performance wise, there isn't an asic resistant algo out there where it wouldn't end up in the top 3, speed wise..

So i stand by my words. It is the best card AMD has to offer at this moment. And again, those are my words and is my own opinion.


 :)

I agree it's the best since ATI was bought out by AMD. Now if they put out a 2xnano it would give nvidia a run for it's
money at the top end.

There it is

It makes little difference to the mining community if this card is delayed. It is too expensive and does not mine efficiently on ethereum.

Hmmm...

I picked up a Nano for testing today.  A Sapphire AMD Radeon R9 Nano, my rig is drawing 200 watts more at the wall mining ETH at stock 1000/500@25mh with the Nano plugged in.  I'm slightly disappointed, although nice & warm.

What drivers are you using please?  I'm using the latest Crimson, Catalyst 15.8 with driver 15.300.1025.0

ETA:

I have stripped the rig down, re-installed everything and with just the Nano plugged in system is using 230w.  Mobo, CPU etc take 75w, meaning Nano now taking 155w at wall mining ETH @stock.  Not as good as the OP, but getting better.

I use 280x to mine Ethereum. There is no difference if I use 14.6 or 15.8.

I tested with Win 10 Pro, Latest Crimson drivers 15.11 or so i thought it was. Not sure, i'd have to check.

Mine is an XFX R9 Nano. But that wouldn't make any difference i think.

Thanks, Win 7 on the rig with the Nano.  Maybe I should try 10.

Prices seem a little high, but the savings on power and cooling might make them worth the price?

i´m planning on buying new gpus for mining..

but 650 usd for a Nano to get 25 Mh/s.. hmmm

long life my 7950/280x`s  ;D

Not worth it. You can buy a 7990 for $300 and undervolt and under clock it. You have higher efficiency and more mining hash.

True but you will have bought an old technology, old card, plus, i'm not so sure about your statement though.

His statement belies the fact that Southern Islands aka 7xxx and all their rebadges (R9 2xx/3xx) is still the best hash/watt/$$ you can get on the AMD side. 

The only new chips AMD has put out at a more efficient nm process are the Fury cards, and their mere cost alone removes them from hash/watt/$$ considerations.

they are still 0.28 nm: AMD just added some CUs and changed memory interface.

!

Thanks for the correction, i was imagining the Fiji chips at 22nm for some reason.  Still on the 28nm TSMC process i see.

I also am a bit surprised at the Nano / Fury / Fury X hash numbers.  Was expecting better.  Guess it goes to show that most algorithms are definitely not bandwidth limited these days.

Most algorithms are memory speed (frequency) or latency limited. For example, for Ethereum mining, there is no benefit of using HBM.

Hello, I understand you're the resident r9 nano expert. I am new to nano and have it running in a rig at a consistent 78c degrees with the fan at 100% - my question is will this card survive or is there a max temp you'd recommend for 24 hour 7 days a week operation? Thank you in advance.

haha, i completely forgot about this thread :p

Funny to bring it up again, reading my posts i feel like a kid in a grown up world.


Anyhow, Nano's are reference models, they're designed to be able to run at such temperatures.
However, i wouldn't recommend it to have them running at or over 80 degrees for a long period of time.

What you should do is start with pulling that voltage down by 100mV, they can easily handle it.
That'll get your heat down significantly.

Greetings and success!

I will try that - thank you so much for your prompt response! :)

Hi Nano-Fan,

I know this is an old thread, but figuered I just use this one intead of creating a new one.
Mining ETH I get ~26 MH/s with the latest drivers from AMD.
I was wondering if higher hashrates are possible and if you (or anyone else with a R9 Nano) can recommend any drivers + tweaks for the Nanos?

Thanks,
KW

EDIT: I did some undervolting and slightly overclocking and managed to get 29 MH/s from the R9 Nanos! Anything else that can be tweaked?

Your at the max of the card on Eth/Etc. You may want to run it on Zcash/zcl. They get 400+h/s pretty easily. Or possibly dual mine with it.

Ok, thanks. Right now I am dual-mining DCR and ETH. I checked ZCash, with current prices ETH is slightly more profitable.
I wonder if there are any mining algos that make good use of the High Bandwidth Memory (HBM) of the Nanos?

For a reference I run radeon 7990 cards and they certainly doesnt shine in Eth mining but when it comes to zcash its rather great.. Bought 3 7990s for under 300 USD 4 weeks ago. Downvolted to 1 volt and underclocked to 900 Mhz GPU. 560 sols/s and 260W per card.

For such old shite its pretty impressive I must say :D

That's pretty impressive. Well I got my new R9s for 360 EUR (a ~$400), they are dual mining right now @ 30 MH/s ETH and 900 DCR.

You may also want to R9 for the ZEC.

Can I see a screen? Can´t believe that 🙈

I run the cards at 800MHz and can get about 480H/s. So it is possible to get 560 around around 900MHz.

nice but i dont see definite answer. How much hashrate it can provide in modded state?
