One more update from sp on his open source and free fork of supminer (ccminer) now called X16r/X16s/C11 Spmod-git #9 (source) as it is no longer only for X16 algorithms. As the change in the name implies the the latest update adds faster C11 algorithm support and the optimizations to it should make it up to 33% faster than before, making the performance on par with the other fastest C11 miners such as T-Rex 0.6.1 and z-enemy 1.17. There are not only C11 performance improvements however in the latest update, it also comes with performance optimizations for X16 and X16S (faster bmw, shavite-cubehash), so better hashrate for these as well. The biggest advantage of this miner is that it is open source and comes with no developer fee built-in, meaning that all the performance you get is available to you and then there is also the source code available as well to learn from, modify and use to compile yourself.

Nvidia has announced its new generation of GPUs with the new GeForce RTX platform and while they do seem interesting in terms of new graphics capabilities, they do not seem that attractive for miners at this point. The whole focus of the new NVIDIA Turing architecture utilize in the GeForce RTX platform is on real-time ray tracing, artificial intelligence, and programmable shading to make games even more realistic in terms of graphics. As far as performance for mining goes the new architecture will apparently not offer any significant performance improvements or power efficiency to be a really attractive option for miners. That is at least initially, unless the new Tensor Cores for the AI computing horsepower turn out to be usable for crypto as well and utilizing them could help drive performance up.
Price wise the new GeForce RTX 2080 Ti, the successor of the GTX 1080 Ti, the new GeForce RTX 2080, the successor of GTX 1080 and the new GeForce RTX 2070, the successor of the GTX 1070 are not that attractive either. That of course goes for the initially announced prices of the Founders Edition series from Nvidia that are available for pre-order on Nvidia’s website in some regions with expected delivery around mid-September. For gamers buying a single of these GPUs it might be fine, but for miners these prices are definitely not very attractive with the current crypto market conditions and the expected performance improvement in the range of up to 10-15% up, at least initially.
We are still eager to get our hands on the new Nvidia RTX GPUs and play around with them to get some first hand experience and see the performance numbers, but you should probably not get very excited just yet… if you are on the market for more GPUs, it might be a wiser idea to look for good deals on used video cards from people that are selling their mining equipment purchased last year.
One more update from sp on his open source and free fork of supminer (ccminer) called Raven x16r/x16s Spmod-git #8 (source) with a bit more extra performance optimizations that should bring faster x16R/X16S with 5 to 7% over the previous release. It is always good to have competition, especially with open source code, though the z-enemy miner 1.16 released a few days ago seems to be a bit faster.
As a recommendation to get the maximum performance with this miner you should try to overclock the memory 500 MHz or more (depending on your GPU) and mine with a fixed difficulty at the pool (normally set the difficulty parameter to around half of the hashrate of the mining rig), so for example for a 100 MHS rig you should set -p d=50 in the bat file for running the miner. There is also an upcoming fork for Raven (RVN) that should take care of the difficulty readjustment problems it is currently having, so you should keep an eye out for mining RVN to become interesting soon again and not only at times of low difficulty for half a day every few days.
