https://blogs.nvidia.com/blog/2021/05/18/lhr/Because these GPUs originally launched with a full hash rate, we want to ensure that customers know exactly what they’re getting when they buy GeForce products. To help with this, our GeForce partners are labeling the GeForce RTX 3080, RTX 3070 and RTX 3060 Ti cards with a “Lite Hash Rate,” or “LHR,” identifier. The identifier will be in retail product listings and on the box.
This reduced hash rate only applies to newly manufactured cards with the LHR identifier and not to cards already purchased.
