What's the best computer to run Millumin ?

This article explains what is important to consider, when choosing a computer to run Millumin. It also shows typical configurations, so you could compare them and find one that fits your needs.


Millumin mainly uses the graphic card, so the better your graphic card is, the better the performances are.
When possible, choose a model of computer with a dedicated graphic card (GeForce or AMD, not only an Intel one). You can compare graphic cards scores on this website. On the other hand, the eGPU is a very good alternative to use high-end graphic cards.

If you uses multiple graphic cards, keep in mind that real-time rendering can only be processed by a single graphic card, and the result must be pushed to other graphic cards, which is time consuming (the other softwares have this hardware limitation as well).

The drive is important too. If you use big files, you need a good one that can read fast enough : for example an internal SSD, or an external RAID drive.
The CPU speed or the RAM size are not that important nowadays.

For codec recommendations, please read this post.
And at some point in your project, click on the "Optimize" button, to follow the recommendations provided by Millumin.

Typical Configurations

However, every project is different, and there is so many factors that can impact performances : how many layers, how many movies, how many outputs, how many capture cards, soft-edge or not, ... Thus, choosing the right hardware is not an exact science.
But we can study typical configurations to get a good idea about how a system performs, and if it fits your needs. Please find a list below :

For sure, the MacMini 2018 does not feature the most powerful GPU (Intel UHD Graphics 630), but thank to its Thunderbolt 3 port, you can connect an eGPU to get a very great graphic card.

Hardware : MacMini (2018 / Core i3)   +   Razor Core X   +   Gigabyte Radeon RX Vega 56
Price : $800 + $300 + $350 = $1450
Software : macOS 10.14.6 / Millumin V3
Difficulty : plug-and-play, but be sure all displays are connected to the eGPU

Performances :

  • 5 x 1080p60 outputs (3xDP + 2xHDMI)
    - all outputs are frame-sync
    - the displays must share the same format (1080p60 for example)
    - the eGPU can handle a lot of work (many layers with movies, shaders, ...)
    - we recommend using the codec HAP for optimal performances
    - if the eGPU is overwhelmed, the outputs may be out-of-sync, but as soon as the usage comes back to normal, the outputs will resynchronize

  • 3 x 4K@60 outputs (3xDP)   +   1 x 1080p60 monitor (1xHDMI)
    - the monitor is used for Millumin's interface
    - FPS steady at 60fps when playing 3 x 4K@60 HAP movies (this is not the limit of the eGPU performances)
    - you can get up to 12 x 1080p60 frame-sync outputs using 3 x Datapath FX4 (see this tutorial)
    - or you can connect the 3 x 4K@60 outputs directly to a Barco E2

  • 3 x 4K@60 outputs (3xDP)   +   1 x 1080p60 monitor (1xHDMI)   +   inputs
    - additional hardware : Sonnet Echo Express SE III + Blackmagic Decklink Duo 2 ($500 + $500 = $1000)
    - FPS steady at 60fps when playing 3 x 4K@60 HAP movies and capturing 2 x 1080p30 cameras

  • 5 x 4K@60 outputs (3xDP+2xHDMI)   +   1 x 1080p60 monitor (1xHDMI)
    - the monitor is used for Millumin's interface
    - FPS steady at 60fps when playing 3 x 4K@60 HAP movies and using 2 x copy-layers to replicate 2 of these movies

Since all calculation will be made on the eGPU, the performance will be very close to using any other computer.
Please report to "MacMini + eGPU" configuration.

Such MacBookPro does not feature a Thuderbolt 3 port (only Thunderbolt 1 or 2).
We do not recommend such models to use a eGPU.

We ran a test with the first generation of MacBookPro Retina (2012 / GeForce 650M).
This "now-quite-old" machine is able to run 3 x 1080p displays, even with several big movies. It can also run 4 x 1080p displays with a sligtly affected framerate.
See this test.



We planned to show other typical configurations, such as MacBookPro Touchbar, iMac Pro or MacMini 2018 alone. Stay tuned.
