All About BTC, LTC, ETH mining as well as other alternative crypto currencies
There is now an sgminer fork for GPU mining Espers (ESP) that uses HMQ1725 algorithm available (source) that works on AMD GPUs. The miner is still in an early beta and you may experience issues trying to use it, it is recommended to be with 15.12 drivers as older or newer versions might not work, the latest Crimson release does not for sure. Below you can find a working 32-bit Windows binary or you can compile from the source, though it seems that there are some issues with the source that still need fixing for problem free compilation. We were able to make the GPU miner for ESP work with about 530 KHS in terms of hashrate on an AMD Radeon 280X GPU or with other words a few times higher hashrate than on a high-end CPU using the CPU miner for hmq1725. We were not able to make the miner work properly on 290X, nor on Nvidia GPUs using OpenCL, so if you try the binary you are welcome to report your experience with it.
