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.

ccminer-maxwell-1-5-git-sp-mod

We have compiled a windows binary from the latest code of the ccMiner 1.5-git SP-MOD fork of the Nvidia miner optimized for Maxwell GPUs by SP (source). This miner includes the latest features available from tpruvot’s fork of ccMiner such as extra nonce support, however the main difference is that it is a version designed to provide the maximum performance on Maxwell-based Nvidia GPUs using Compute 5.0 (GTX 750, GTX 750 Ti) and Compute 5.2 (GTX 970 and GTX 980). If you are using an older Nvidia-based video card for mining crypto currencies you might want to stick with the tpruvot’s ccMiner fork that works with cards supporting Compute 3.0 or newer. The optimizations by SP do provide some extra hashrate and our test has shown a bit higher performance as compared to the latest code from tpruvot, testing with GTX 980 at stock frequency on X11 algorithm we are getting about 7900 KHS or slightly faster with the SP fork. The windows binary was compiled from the latest source with VS2013 and uses CUDA 6.5,s o make sure you have the latest video drivers installed.

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 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.
