GALAX is the first graphics card manufacturer to confirm NVIDIA's GeForce RTX 30 LHR (Lower Hash Rate) series which is designed to combat cryptocurrency mining. The company has launched two cards under this category which are based on the new Ampere GPU SKUs.

The GALAX GeForce RTX 3080 LHR and GeForce RTX 3070 LHR graphics cards are custom designs and nothing on these cards is changed except the underlying GPU SKU which has been updated to GA102-202 (LHR) for the RTX 3080 and GA104-302 (LHR) for the GeForce RTX 3070. With these new GPUs installed, the graphics cards will be limited to a 50% hash rate in cryptocurrency mining algos, making them unprofitable in such cases.
