The ADLINK Pocket AI portable GPU is a new twist on the classic concept of external GPUs, or eGPUs. The Pocket AI is a Thunderbolt 3, NVIDIA RTX A500 4GB GDDR6 GPU in a form factor that is not much bigger than a deck of playing cards. ADLINK is marketing the portable GPU as useful for AI work, hence the name, but it can be used for anything which requires a GPU, such as rendering and video editing.
