The latest automatic update of BetterHash adds the suffix "LHR" to the names of all Nvidia graphics cards that are equipped with a reduced hash rate GPU (LHR stands for "Lite Hash Rate"). Once we receive more data, we'll split the GPU estimations on our website and display separate reports for regular and LHR NVidia GPUs. Hash rates are different, and we'll treat those GPUs as distinct from now on. The update will improve profit switching accuracy for everyone.
