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
