Crypto Mining Performance of the New Nvidia GeForce GTX 980

19 Sep


Nvidia has just introduced their new high-end Maxwell-based GPUs the GTX 980 and GTX 970 and the expectations from them in terms of performance for crypto mining are pretty high. After earlier this year we saw what the mid-range GTX 750 Ti, the first Maxwell card was capable of, we already had high hopes for the upcoming faster models. Apparently we are not going to be disappointed by the performance we are going to get, below you can see a chart with the hashrate that the new GeForce GTX 980 (GM204) provides in various crypto algorithms. These were actual tests ran using the latest versions of CudaMiner and ccMiner with support for Compute 5.0 with no special optimizations that could possibly benefit the new cards any further.


In the table you can see the algorithm, the hashrate you get with the GTX 980 and the TDP usage percentage. The GeForce GTX 980 has a TDP rating of just 165 Watts, so with this maximum power consumption you can see that not all algorithms are utilizing it at 100%, meaning the actual power usage is lower. The performance you can expect to get from the GTX 980 is roughly about three times higher with about three times more power usage as compared to the GTX 750 for crypto mining. The initial price of the GTX 980 however could be a reason for miners to go to the slightly slower GTX 970 model for crypto mining as you should be able to get two GTX 970s for a price a bit higher than for a single GTX 980 and the performance you will get from the two cards should be significantly better than from a single GTX 980.


The results posted above are with a reference GTX 980 card running at stock frequency, considering that the GM204 does overclock really good, higher results can be attained when the card is overclocked. The second set of results (the OC ones) are achieved with the card overclocked to GPU at 1520 MHz, Video RAM to 8250 MHz and TDP limiter set to the maximum 125%. This is really pushing the GTX 980 to its stable maximum limits as the card really does handle serious overclock pretty well. Unfortunately we do not have access to a GTX 970 GPU for the moment, so we cannot yet test to see the difference in performance, though it should not be that high, but the 970 should be available at a much more attractive price, so it could be the more obvious choice for crypto mining rigs. The GTX 750 Ti still seems like a good more budget oriented solution for mining.

You should be well aware of the fact that some ccMiner forks are nor working very well with the GTX 980, we’ve had some weird results showing like way too little load and low hashrate or the miner crashing, also one of the reasons that not all available algorithms are listed. The GTX 980 and GTX 970 does support Compute 5.2 and not all forks of ccMiner we have used for testing are compiled to even support the Compute 5.0, the CudaMiner has not been updated for a while and we have used the latest official release for the Scrypt testing… not that you would use a GPU nowadays to mine Scrypt crypto coins anyway.

Where is XMR and XCN?

same question as Sasa’s :)

We are having some trouble with some of the miners, including forks with M7 and Cryptonight algorithms, that is why they are not included – low performance with very low load of the GPU or inconsistent hashrate.

thanx for the prompt & comprehensive comment.

can you review the gtx 970?!
interested in seeing its x11 performance


September 19th, 2014 at 20:05

As long as the GTX970 produces 5700 KHS in x11 it would be a better KHS to $ deal then a 750ti.
I don’t see how the GTX980 is a good deal though. I get about 2400 KHS (not overclocked) from one 750ti that costs $139 at NewEgg, which is ~17KHS per $. The cheapest GTX980 at NewEgg is $549 (not that any are in stock) which even overclocked (7106KHS) is ~12KHS per $. And your Watt usage for running 3 750ti’s overclocked would still be lower then the GTX980 overclocked usage (and the corresponding KHS of the overclocked 750ti would be increased).
Maybe my math is wrong?

hey boss, if you find the x11 kh/s for the gtx970 do u mind sharing it?


September 19th, 2014 at 20:36

I haven’t found gtx970’s x11 kh/s, I was just saying as long as it is above 5700 it will be a great deal.

Actually with the bitcoin price as it is, it is better to just buy the bitcoin straight. With the $549 for a GTX980 you could get 1.392 BTC ($395 per BTC), which given the avg payout of nicehash per day is .0000002 per khs (so 7106KHS = .00142 with an overclocked GTX980), it would take 980 days to a BTC ROI (ie get 1.392 BTC).

*I consider nicehash the easiest way to mine with a set and forget it type style. Granted playing the alt coin market could return much higher per day BTC.

The 970 produces about 5800 kh/s x11 (no OC) in my initial tests, and also shows strange behaviour with XCN. Here’s a link to some performance numbers with different cards that I tested with the latest Nvminer


September 24th, 2014 at 22:30

@Preciousillusion: Not bad, just passes the dollar to khs ratio of a 750ti. Do you know what the watt usage is (with like a kill-a-watt plug or something)?


September 24th, 2014 at 22:56

@d: Unfortunaly not :(


October 21st, 2014 at 13:09

There are few people working on the ccminer to improve 900 series performance, the actual hashrate for an overclocked 980GTX TODAY is about 8MH/s in X11.
Please update the blog.
