NVIDIA announced today that it's halving the hash rate for Etehereum cryptocurrency mining on the new GeForce RTX 3080, 3070, and 3060 Ti graphics cards to make them less desirable for miners.
The company will add "Lite Hash Rate" or "LHR" identifiers to retail product listings and boxes for all these new nerfed graphics cards that will start shipping later this month.
