GPU
Graphics Processing Unit - the chip on your video card, and one of the two main options for mining Malairte.
A GPU is the parallel-compute chip on your video card (e.g. NVIDIA RTX, AMD Radeon). For Malairte, GPUs are typically faster than CPUs because mining is highly parallelisable. The same card you use for games or rendering will mine MLRT; you do not need a specialised mining card.
