Due to the release of the BIOS update with the Resizable Bar support for NVIDIA RTX 3000 video cards, quite some people feared that the hash rate (efficiency in mining) of new video cards will increase, as will the demand from miners. Others think that the hash rate will decrease with a BIOS update. Therefore, we conducted our own testing using the example of NVIDIA GeForce RTX 3060 Ti in ETH mining.
According to our tests, when the RTX 3060 Ti video card running with minimal frequency tuning (lowering the core frequency and power limit of the video card in the Gigabyte Aorus Engine utility), the hash rate of the card remained at the level of 50-52 MH/s, both with the use of the Resizable Bar and without it. Serious memory overclocking raises rates up to 60 MH/s, but at current prices it is not very reasonable to risk the card like that.
It turns out that the hash rate has not decreased, but has not increased either. At least when using one video card, the BIOS did not affect the mining of cryptocurrency in any way, including fears of blocking (since NVIDIA reduced production for the RTX 3060 and promise limits for the next game models).
But in games, the update improved the performance nearly everywhere, even the overall performance boost wasn't the part of NVIDIA's promise.
