All About BTC, LTC, ETH mining as well as other alternative crypto currencies
Ethminer 0.9.41-genoil-1.0.4b3 (source) is the latest release of Genoil’s CUDA miner forked from the official ethminer that is designed to work on Nvidia CUDA GPUs, but will also work on AMD OpenCL GPUs as well. The latest version adds some useful features for both AMD and Nvidia miners, though there is not much of a difference in terms of performance compared to older releases, so do not expect to see faster hashrate. In fact the hashrate on AMD GPUs has been decreasing over time due to the increasing size od the DAG files used by the miner for mining Ethereum’s Ether (ETH) coins.
The latest release contains more advanced benchmark options that allow you to check how performance changed or will change in time, there is an option to set a custom DAG storage folder and even support for stratum mining without a proxy, although currently limited to support only for Coinotron with more pools to come. We ran a quick test to check how the hashrate changed over time between block 1 and block 1 million of Ethereum on an AMD Radeon R9 280X GPU and on Nvidia Geforce GTX 970 GPU. As you can see from the results below the performance has dropped quite a bit on AMD, but has not changed on Nvidia, do note however that Nvidia-based video cards are slower in terms of mining performance for Ethereum… at least for the moment.
GeForce GTX 970:
Block 1 – 17.31 MHS
Block 1M – 17.31 MHS
Radeon R9 280X:
Block 1 – 25.95 MHS
Block 1M – 21.49 MHS
