nvidia-geforce-gtx-980

Back in September with the release of the new Maxwell-based NVidia GPUs, the GTX 970 and GTX 980 we did some performance testing of the GeForce GTX 980 hashrate using the available at that time ccMiner and CudaMiner miners. Today, a bit over two months later we’ve decided to check how hings have progressed in terms of performance improvements of the various crypto mining algorithms with the latest optimizations available in ccMiner. We’ve used the just posted Maxwell-optimized ccMiner 1.5-git ccMiner fork from SP to get the performance results from the same GTX 980 GPU running at stock frequencies (overclocking can further increase performance).

There is no surprise that there are some significant performance improvements in various crypto algorithms that have been achieved using various optimizations, but to our surprise there ware a few algorithms that did perform worse. The results we got from Groestl, HEFTY1 and JHA were a bit lower with the latest ccMiner than what we got in terms of performance back in September. Some other algorithms also don’t seem to have very big performance improvements such as Keccak, Luffa512 or NIST5, but the more popular and still profitable to mine algorithms do come with nice improvements. You can thank for the increase in performance to all of the developers that continue to work actively and optimize the performance out of which SP and tpruvot seem to be the most active lately, djm34, tsiv as well as others who have contributed code and also Christian Buchner and Christian H. – the creators of the ccMiner in the first place. Their code contributions and efforts in releasing their work publicly deserve some appreciation from the miners who are using Nvidia GPUs in order to keep them motivated. Below you can find the official donation addresses where you can send some coins for a beer or more to the each of the developers:

ccminer-1-5-git-tpruvot

We have compiled a windows binary from the latest (source) of ccMiner 1.5-git fork by tpruvot as he has added support for the Extra Nonce feature used by services such as NiceHash or WestHash to maximize the mining performance. So if you are currently leasing your Nvidia GPU mining hashrate at NiceHash or WestHash you might want to try out the latest code of this ccMiner fork. Do note that there is still no official release of 1.5 by tpruvot and this windows binary is compiled from the latest source available on GitHub. There are also some increases in performance as compared to the previous release, so you should notice a slightly better hashrate in some algorithms. The windows binary available for download below is compiled for Compute 3.0, 3.5, 5.0 and 5.2 Nvidia GPUs using VS2013 and CUDA 6.5, so make sure you have updated your drivers if you still don’t have ones installed with CUDA 6.5 support.

ccminer-149-tpruvot

The ccMiner for Nvidia GPU mining for crypto coins is finally getting more like cgminer for AMD in terms of supported features thanks to developers like tpruvot. The more recent versions including the latest 1.4.9 of his ccMiner fork (source) have introduced features such as the ability to control the intensity of the GPU load, basic API functionality to get stats available to other software, support for JSON-based config file and now also nvapi/nvml support for GPU monitoring and possibly control. We have compiled a Windows binary from the latest source since there is still no official one released with the latest features and you can find a link to download it below. The binary is compiled with VS2013 and CUDA 6.5, however it includes support for Compute 3.0, Compute 3.5, Compute 5.0 and Compute 5.2 GPUs and not only for the new Maxwell-based cards. The latest version also does include some of the optimizations from SP’s ccMiner fork optimized for Maxwell, so you can expect to get similar performance on Maxwell cards such as GTX 750 Ti or GTX 970/980 with this release from tpruvot. The only thing that we still haven’t figured out is how to make GPU monitoring work as we are getting an error message saying that it i not available.

Update: There is now an official release of 1.4.9 available with some additional fixes and changes in the API, so you can download it directly from tpruvot’s Github repository, link below is updated to point to it.
