Blackmagic eGPU Hands-on with 2018 Macbook Pro & LG 5K!

The Blackmagic External GPU with RX 580: A Game-Changer for MacBook Pro Owners?

For those who have invested in a beautiful 5K display, such as an LG Ultrafine Thunderbolt Display or a 4K Cinema Display, using it with a MacBook Pro can be a frustrating experience. The reason is that the MacBook Pro only has limited ports, which means you're stuck with HDMI or DisplayPort options, and unfortunately, these don't match up with the newer Thunderbolt 3 displays.

This limitation is exactly what Blackmagic's new External GPU (eGPU) enclosure aims to solve. With the eGPU, owners of a base Touch Bar MacBook Pro can now take advantage of their existing Thunderbolt ports to connect an external graphics card that supports their display of choice. The eGPU enclosure features a Thunderbolt 3 port, which is the same one used by the MacBook Pro, making it easy to plug in and use.

The eGPU unit itself is compact and comes with a power cable and a Thunderbolt 3 cable. To connect the display, users simply need to plug in the power cable to an outlet or a wall adapter, as well as the Thunderbolt 3 cable into the MacBook Pro's port. The eGPU enclosure is designed to be short, making it easy to place under a desk or other surface, although there is no option for a longer cable if you want to hide it from view.

When using the eGPU, users will need to plug in a Thunderbolt 3 DisplayPort cable to make use of the external graphics card. Fortunately, Blackmagic provides this cable with their eGPU unit, making it easy to test out the feature right away. As soon as the eGPU is plugged in and power is applied, the MacBook Pro springs to life, displaying a notification icon on the screen.

The eGPU's performance was put to the test using Geekbench and OpenCL benchmarks. The results were staggering - with an almost 33,000 score for the integrated graphics card, compared to just under 110,500 for the RX 580 in the eGPU enclosure. This represents a massive improvement over the integrated graphics, making it clear that the eGPU is capable of delivering top-notch performance.

One question on everyone's mind is whether this means that owners can now skip down-sizing their MacBook Pro from 15 inches to 13 inches and still get great performance when they need it. The answer is yes - with the eGPU, users can plug in an external graphics card and enjoy similar performance to what they would have gotten with a larger, more expensive MacBook Pro. This makes the base Touch Bar model an attractive option for those who need serious power but don't want to break the bank.

Overall, Blackmagic's External GPU enclosure with the RX 580 is a game-changer for MacBook Pro owners who want to take advantage of their existing Thunderbolt ports and connect high-end displays. While there are some limitations, such as the graphics card being built-in and not removable, the eGPU still represents an exciting new development in external graphics solutions.
