One of the biggest selling points of having even a single Thunderbolt 3 port on your notebook was the ability to support and connect eGPU solutions to get that extra graphics performance increase. Whether it’s playing games or doing some graphically intensive work, the eGPU always came in handy when connected via Thunderbolt. Unfortunately, no M1 Mac model that Apple announced today supports these solutions, despite having Thunderbolt ports.

Whether you order the M1 MacBook Air, the M1 MacBook Pro, or the M1 Mac mini, you’ll no longer see eGPU support with these models. We found this out by checking each product page’s specifications and noticed that there’s no mention of the Blackmagic eGPU, which is Apple’s preferred external GPU enclosure. With that out of the way, how do users intend on getting that increase bump in graphics performance?
