Why Desktop eGPUs Are Finally Worth Buying In 2026

AOOSTAR’s AG03 is a budget Thunderbolt 5 eGPU enclosure with Oculink support and an 800W power supply.

It delivers better performance than the older AG02, helping mini PCs, laptops, and handhelds get closer to desktop GPU speeds.

The open-air design and included power setup make it flexible, but the missing cable is a drawback.

Compatibility is not universal, with some systems and Linux setups still facing issues.
