ccMiner SPMOD Release CUDA 6.5 vs CUDA 7.5 Performance Comparison

5, Jan 2016

ccminer-spmod-cuda-65-vs-75

The ccMiner SPMOD fork for Nvidia Maxwell GPUs (source) has recently been migrated to use the newer CUDA 7.5 from the older CUDA 6.5. The latest version with CUDA 6.5 support was version ccMiner 1.5.74 and the latest version is ccMiner 1.5.78 that already uses CUDA 7.5. The first release with CUDA 7.5 had not so good performance and was slower in some algorithms in terms of performance as compared to the latest CUDA 6.5 release, but the latest code has been optimized to offer similar or even better hashrate in most supported algorithms. We took an Nvidia GeForce GTX 970 (Gigabyte GV-N970WF3OC-4GD) running at stock frequencies for a spin with some of the currently popular algorithms to compare the performance of the latest CUDA 6.5 to the latest CUDA 7.5 release of ccMiner spmod. The results in the table clearly show that aside from NeoScrypt the latest CUDA 7.5 release offers very similar or even slightly better hashrate compared to the latest CUDA 6.5 version. The hashrate of X13, X15 and Qubit is still slightly slower, but not much. So unless you are mining NeoScrypt you should have no reasons not to upgrade to the newer CUDA 7.5 releases and soon we are probably going to see even better performance thanks to further optimizations of the code. Do note however that some other Maxwell GPUs might have some more variance in terms of performance difference between the two compared versions.

Updated Windows Binary of the ccMiner 1.5.78-git Fork by SP for Maxwell

3, Jan 2016

ccminer-1-5-78-spmod

New update in the form of a Windows binary compiled from the latest Git source code of the ccMiner 1.5.78-git SP-MOD fork by SP optimized for the latest Maxwell-based video cards (source). The new release comes with more performance improvements for various algorithms under CUDA 7.5 trying to reach the same performance as with CUDA 6.5, the latest CUDA 6.5 release was version 74. Do note that the SP-MOD fork of ccMiner is designed for Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970, GTX 980 and GTX 980 Ti and GTX Titan X. The Windows binary release we have made available here is with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based Nvidia video cards compiled with CUDA 7.5 and VS2013.

Updated Windows Binary of the ccMiner 1.5.77-git Fork by SP for Maxwell

ccminer-1-5-77-spmod

Another update in the form of a Windows binary compiled from the latest Git source code of the ccMiner 1.5.77-git SP-MOD fork by SP optimized for the latest Maxwell-based video cards (source). The new release comes with a lot of optimizations in the performance of the Lyra2REv2 algorithm under CUDA 7.5, the last CUDA 6.5 compiled release was version 74. There is also some improvement in Neoscrypt hashrate, but it is still slower on the CUDA 7.5 releases, as well as some other minor improvements in other algorithms. Do note that the SP-MOD fork of ccMiner is designed for Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970, GTX 980 and GTX 980 Ti and GTX Titan X. The Windows binary release we have made available here is with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based Nvidia video cards compiled with CUDA 7.5 and VS2013.
