teamred miner 8 amd radeon 7 hashrate ethereumTeamRedMiner is specialized software for mining cryptocurrencies on AMD graphics cards, with support for over 25 different mining algorithms. In the latest version of Team Red Miner 0.8.0, released on January 19, 2021, the developers made major changes to the program code, rewriting the kernel for all types of GPUs. In the eighth version, new operating modes B-mode and C-mode have appeared, with the help of which you can choose a more productive or more energy efficient mode of operation of video cards in mining. The operating mode is set using the --eth_aggr_mode command. So, for example, in C mode, the AMD Radeon 7 video card in Ethereum mining produces 12.5MH/s more than in the previous version of the miner, which in total gives a little more than 100Mh/s. Power consumption increased by only 8W to 192W. For other models of video cards, the changes are the same significant, although not as dramatic as for the Radeon 7.

For Polaris video cards (RX470 - RX580), a new miner and a new B mode gives an additional 0.4Mh/s and at the same time the power consumption becomes 0.89W less
For Vega 56/64 video cards hashrate increased by 0.27MH/s with a decrease in power consumption by 5.8W
RX5700 with the same hashrate of 60Mh/s reduced power consumption by 9W
Unfortunately, the RX5600XT did not get any serious advantages, so for these video cards, mode A remains by default.

More details with changes in hash rate, power consumption of various models of video cards and different versions of miners can be studied from the table below:

Important: TeamRedMiner 0.8.0 for Polaris video cards with 4Gb does not provide any advantages, it makes sense to switch only for 8Gb versions. The developers also warn that with the transition to the new version, the memory load will increase, due to which your current frequency and voltage from memory may not work stably and you may have to select the optimal parameters again.
