AppleInsider takes an in-depth take a look at Apple and Blackmagic’s Thunderbolt-enabled eGPU, testing the MacBook-accelerating with a gamut of assessments from 5K gaming to video modifying. We present you every thing that units this eGPU aside from the pack.

The Blackmagic eGPU, in-built cooperation with Apple, may appear expensive at $699, but it surely comes packing a Radeon Professional 580 GPU, the identical chip that comes within the top-spec 2017 5K iMac. By itself, the silicon is price just below $300, and now you can get it bundled with another eGPU’s for round $500.

So why would anybody wish to pay additional for this explicit unit from Blackmagic and Apple?

For one, the Blackmagic is the primary eGPU to assist Thunderbolt Three and USB-C screens like LG’s 4K and 5K UltraFine displays, that means well-heeled MacBook Professional house owners can flip their transportable rig into one thing nearer to a desktop.

If you do not have or do not plan on shopping for an LG UltraFine show, the Blackmagic additionally works with any USB-C or HDMI monitor. DisplayPort screens are additionally supported with the assistance of a separate adapter.

Along with the 2 Thunderbolt Three ports, the Blackmagic packs in 4 USB Three.1 ports and an HDMI 2 slot, besting a variety of competing eGPU packing containers. The additional inputs and outputs can be utilized to attach exterior storage drives, keyboards, mice, or just cost an iPhone.

The Blackmagic works with any Thunderbolt Three-equipped Mac, and it gives 85 watts of charging in your MacBooks. For now, the setup is a macOS-only affair, because the eGPU doesn’t but assist Home windows 10.

From a design standpoint, it is undoubtedly the best-looking eGPU we have ever seen, and it is constructed with high-quality supplies.

This leads us to one of many greatest the explanation why you’d select this eGPU over one other mannequin: extremely quiet fan noise and low temperatures. It options a big fan that sucks air by means of the underside and pushes it out of the highest, similar to the late 2013 Mac Professional.

It is extremely quiet, even at full load, a significant improve from competing that will get more and more loud as working temperatures warmth up. In truth, the Blackmagic is so quiet that we forgot it was on whereas taking part in a demanding session of Fortnite at 5K resolutions.


The eGPU drastically improved the gaming efficiency of a base mannequin 2018 13-inch MacBook Professional with Contact Bar. With the MacBook’s inside Intel Iris Plus Graphics 655 operating at maxed-out decision and excessive video high quality settings, we have been in a position to obtain round 15 frames per second whereas taking part in Fortnite. These speeds dropped all the way down to 7fps at instances and the laptop computer’s followers have been on full blast.

We turned the settings all the way down to round 1080p at medium graphics settings and noticed body charges rise to round 40 to 45fps, however we nonetheless skilled body drops that made the sport unplayable.

Connecting the Blackmagic eGPU and LG’s 5K show, we set the sport’s decision to 5K, or 5,120-by-2,880 pixels. Graphics high quality (clearly) improved and body charges have been hovering at round 30fps. In contrast to the MacBook Professional’s built-in graphics chip, the eGPU was in a position to maintain issues way more constant, with no body drops that ruined gameplay.

Dropping graphics settings to medium boosted body charges to about 40fps, and every thing nonetheless regarded nice.

We additionally hooked it as much as an everyday 4K show utilizing a Thunderbolt Three-to-DisplayPort cable and noticed across the similar 35fps at 4K “Epic” settings.

All through testing, each the Blackmagic eGPU and the MacBook Professional have been whisper quiet.

Photograph & Video Modifying

Should you’re a photograph editor, an eGPU will not actually make a distinction, since apps like Adobe Photoshop and Lightroom largely depend on Mac’s CPU for heavy lifting. We have been hoping to see an enchancment whereas modifying 42MP RAW pictures in Lightroom, however the lag continues to be there regardless of some help from the eGPU.

Video modifying, nevertheless, is a unique story. In Closing Minimize Professional X, the Blackmagic eGPU permits the 13-inch MacBook Professional to export a 5 minute 4K h.264 clip with added results in lower than half the time of the built-in GPU. That places the smaller MacBook Professional’s efficiency almost on par with the bottom 15-inch MacBook Professional. Apparently, in some instances the 15-inch MacBook Professional will get slower when utilizing the eGPU.

For instance, when connected to the 13-inch MacBook Professional, the eGPU reduce processing time in half for a one minute four.5K Pink RAW clip with added results. Nevertheless, the 15-inch MacBook Professional was virtually twice as gradual when mixed with the eGPU.

Stabilizing a 4K clip on the 13-inch with eGPU was mainly simply as quick as the bottom 15-inch MacBook Professional, each with and with out the eGPU. To our shock, the 13-inch MacBook Professional with the eGPU was quicker within the Bruce X 5K benchmark, ending virtually 3 times quicker than the 15-inch MacBook Professional’s discrete GPU.

We examined 4K 60fps Canon Cinema RAW Lite footage in a one minute mission with coloration corrections and a LUT utilized on the 15-inch MacBook Professional, with and with out the eGPU. We noticed an unlimited enchancment not solely in export speeds, however timeline smoothness as effectively. We went from not having the ability to play again the footage in full decision to clean playback in 4K, in each 24fps and 30fps.


We carried out benchmarks by attaching the Blackmagic to a base mannequin 2018 13-inch MacBook Professional and a top-of-the-line 2018 15-inch MacBook Professional with 2.9GHz i9 CPU, 4GB Radeon Professional 560X graphics, and 32GB of DDR4 reminiscence.

Geekbench four’s OpenCL take a look at exhibits us the uncooked graphics efficiency of every GPU, and as you may see, it is a large enchancment over the 15-inch MacBook Professional’s GPU.

We additionally ran the Unigine Heaven gaming benchmark and the 13-inch MacBook Professional with the Blackmagic eGPU significantly outperformed the 15-inch MacBook Professional. The 13-inch mannequin fell behind by a few frames when in comparison with the 15-inch with the eGPU.


Our testing exhibits the Blackmagic eGPU isn’t actually price the additional cash if you happen to already personal a 15-inch MacBook Professional, usually are not a video editor and intend to make use of the with out an exterior monitor.

However, if you happen to personal an LG UltraFine show or a 2018 13-inch MacBook Professional, the answer is certainly interesting. With the 13-inch MacBook Professional, you get added portability when on the go and a quad-core, 8GB Radeon Professional 580 workstation within the residence or workplace, nearing the efficiency ranges of a 15-inch Macbook Professional with i9 CPU.

Total, the Blackmagic eGPU is a specialty product that makes a number of sense for a smaller group of individuals. It is costlier than different options utilizing the identical GPU, and it is not upgradable. Should you want Thunderbolt Three assist and would love a close to silent expertise, nevertheless, there’s nothing else prefer it.
