The Apple 13" MacBook Air (2020) is a great option for longtime MacBook users that want a light, portable, affordable Mac and aren't necessarily fans of the Touch Bar. While you can soup up the 13" MacBook Air (2020)'s process and memory options, there is no way to take advantage of external GPU's to improve graphics performance. The 13" MacBook Air (2020) also only has two Thunderbolt 3 ports on the left side which also limits connectivity options.

The Black Magic eGPU Pro addresses these limitations by allowing the 13" MacBook Air (2020) to take advantage of the more connectivity options, higher graphics performance, all while charging the Mac at up to 85W over USB Power Delivery.

The Black Magic eGPU Pro has four USB 3.2 Gen 1 (5Gb/s) Type-A ports supporting BC 1.2 1.5A charging, one standard DisplayPort 1.4, one HDMI 2.0 port, and two Thunderbolt 3 ports.

In fact, we can see that USB 3.2 Gen 2 (10Gb/s) drives like the SanDisk Extreme Portable SSD enumerates at USB 3.2 Gen 2 (10Gb/s) speeds when connected to the Black Magic eGPU Pro's Thunderbolt 3 port.

The same SanDisk Extreme Portable SSD only enumerates at USB 3.2 Gen 1 (5Gb/s) speeds when directly connected to the Apple 13" MacBook Air (2020) so you get faster USB file transfer speeds when using the Black Magic eGPU Pro with USB 3.2 Gen 2 (10Gb/s) drives.

The Black Magic eGPU Pro also has a AMD RX Vega 56 GPU but the discontinuation of this GPU also caused Black Magic to also discontinue this Pro model.
