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.
While LBRY is still in Beta and you need to request an invitation in order to be able to get early access to the platform (currently only available for Mac OSX and Linux), people have been mining the LBRY Credits (LBC) for a while now on AMD via the dedicated sgminer fork or on CPU, but today tpruvot has updated his ccMiner fork (source) with the final 1.8 release that adds support for LBRY Credits mining on Nvidia GPUs as well.
We have compiled a Windows binary of the latest ccMiner 1.8 source code from github and you can download and try it for mining LBC from the link below. It is a 32-bit Windows binary compiled with VS2013 using CUDA 7.5 for Compute 2.0 to Compute 5.2 Nvidia GPUs, though it also works on Nvidia Pascal GPUs. We are going to be testing the miner with different CUDA versions to see if there is a better working combination and if we find such we are going to update the binary. If you are in a hurry to get to mining LBRY Credits however you should be all set to start with this release and enjoy the good performance that Nvidia GPUs provide for this algorithm. Below is a quick benchmark with a few Nvidia GPUs using this Windows binary as an idea to what you can expect in terms of hashrate for mining LBRY Credits.
Mining hashrate for LBRY Credits:
– GTX 970 – 127 MHS
– GTX 980 Ti – 156 MHS
– GTX 1070 – 242 MHS
– GTX 1080 – 313 MHS

Siacoin (SC) is getting a lot of attention lately and there is now a new fork of the miner available made by Genoil (source). The Sia GPU Miner fork by Genoil is for OpenCL, though it works on both AMD and Nvidia and provides some performance optimizations along with other interesting features such as the ability to load external OpenCL kernel file that might be useful for people that want to try modifying or optimizing the CL file. Genoil reports that his optimized OpenCL kernel is capable of providing roughly +18% performance increase on a 7950 and we are seeing some performance boost on Nvidia as well, though more like 3-4% boost on a GTX 970. Nevertheless the fork by Genoil does offer some performance improvement over the Siacoin default miner as it has taken that OpenCL Go miner kernel as a base and even more improvements could be possible for faster performance.
We have a working 64-bit Windows binary available for download below that you might want to try. We have tested it and can confirm that it works on both Sia Nanopool and Siamining pool, though for some reason the hashrate reported by the miner is a bit higher for Nanopool than for the Siamining pool. Do note that this miner does require you to run a separate instance for each GPU in your system, it will by default run only on the first video card it finds. So while things do look very promising for this fork it apparently can use a bit more work to become as easy to be used as the Siacoin Go miner and maybe even better performance wise.
