There is a new closed source miner for the Lyra2rev2 algorithm available for AMD GPUs that is supposed to bring up the performance for owners of AMD-based mining rigs to a similar level of performance currently available to Nvidia mining rigs. The new miner is called mkxminer and is compatible with the more recent AMD GPUs such as Radeon series 200 or newer, including support for the latest VEGA GPUs as well (no asm kernels yet). There are assembler optimized kernels available for some of the supported GPUs for the best performance and the results in terms of hashrate are indeed very good.

It all seems pretty good so far, though there do seem to be some limitations such as the support for mining only on NiceHash at the moment (support for other pools may be added later on) and the lack of clear information how much is the developer fee. There is a dev fee included with this closed source miner, so you are mining for the developer form time to time, but nowhere is clearly stated what is the actual percentage of the fee. There is currently only a Windows version available, though a Linux one is also apparently being worked on as well and should be available soon.

For more details check the official announcement thread of the mkxminer on Bitcointalk…

Here is a ccMiner fork based on alexis78 code, but with added support for the KeccakC algorightm (source) used for CreativeCoin (CREA) mining. KeccakC is a slightly different variation of the Keccak algorithm, but it still requires modified miner to support it, so you still need to use a compatible miner for coins like CREA that use it. If you are looking for an sgminer with KeccakC support check this Windows binary from the official project website (source).

We have compiled a 32-bit Windows binary of the ccMiner frok from cornz with KeccakC support as it was requested by readers and you can download and try it from the link below. It is compiled with Visual Studio 2013 and CUDA 7.5, the supported Nvidia GPUs are Maxwell or Pascal-based ones (Compute 5.0 or newer). The performance we are seeing is similar to that of the original Keccak algorithm, so you can expect to see similar performance if you have mined a Keccak-based coin recently. Again, have in mind that Keccak and KeccakC although similar are not compatible with each other and you need to use the respective algorithm for the coins that use it!

The dstm’s ZCash Nvidia miner has been available for a while and we’ve been keeping a track, but it was only for Linux operating systems – not anymore. With the latest version 0.5.2 the miner is also released for Windows in a 64-bit binary and not anymore available only for Linux miners. The miner is closed source one and comes with a 2% developer fee included. It support Nvidia-based GPUs with Compute Capability 5.0 or later, meaning it is for Maxwell or the newer Pascal video cards. There is support available for stratum as well as for NiceHash’s extranonce, so it can be used there as well without problems for selling Equihash hashrate.

The dstm’s ZCash Nvidia Miner is supposed to be slightly faster than the popular and widely used EWBF’s CUDA Zcash miner that has not been updated for quite some time, so you might want to give the new miner a try. Our initial tests show a bit better hashrate with the same GPU settings as with the EWBF, though the difference is not huge. Do note that dstm’s miner has its own specifics that you need to get used with such as the use of a separate thread for each GPU and getting 6 separate workers on the pool from one mining rig for example. The interface could also use some improvements and some color coding can further help in readability, but in general it is quite Ok even at the moment. Do note that the 64-bit Windows binary is built with Visual Studio 2015, so if you do not have the Visual C++ Redistributable for Visual Studio 2015 installed you might get an error about a missing DLL.
