AMD will not be following NVIDIA in limiting the crypto mining performance of its latest graphics cards. To recap, NVIDIA released the RTX 3060 with an Ethereum mining cap, which it then broke by releasing development drivers that had the cap disabled. Nonetheless, NVIDIA is expected to refresh its existing Ampere cards with comparable mining caps enabled, so we doubt it would make the same mistake twice.
According to PCGamer, a product manager at AMD (Nish Neelalojanan) insisted that AMD would 'not be blocking any workload' on its Radeon RX 6000 series cards, including crypto mining. Neelalojanan emphasised that AMD has designed RDNA 2 for gaming rather than for mining. Specifically, Infinity Cache and RDNA 2's relatively small bus width does not make the RX 6000 series the best for crypto mining.
As Cryptoage has demonstrated, RDNA 2 cards only achieve about half the ETH mining hash rate of Ampere cards like the RTX 3090. The RX 6800, RX 6800 XT and RX 6900 XT average just over 60 MH/s, or just ahead of the RTX 3060 Ti. Ultimately, the open-source nature of AMD's Linux drivers would make it difficult for the company to restrict crypto miners.
