Test Machine Specs

The benchmark was recorded on the base model Mac mini M4, with one storage upgrade:

• Chip: Apple M4
• Memory: 16 GB unified memory
• Storage: 512 GB internal SSD
• CPU upgrade: none
• GPU upgrade: none
• Extra memory: none

The only upgrade here is the 512 GB SSD. The reason that matters is simple: game development projects can get large fast, and 256 GB can become miserable once you install engines, sample projects, build files, plugins, and assets.

What This Benchmark Measures

This benchmark focuses on practical game development behavior, not just raw FPS.

The test looks at:

• Unity First Person Shooter sample first load time
• Unity FPS sample play mode performance
• Unity High Definition sample load and shader compilation behavior
• Activity Monitor memory usage and memory pressure
• Frame rate behavior in simple and heavier Unity scenes
• Comparison against previous Unreal Engine results on the same Mac mini M4

That matters because editor performance is not only about FPS. Load time, shader compilation, memory pressure, editor responsiveness, and real usability matter just as much.

Unity Test One: First Person Shooter Sample

The first Unity test uses the First Person Shooter sample project. This is a useful starting point because it gives us a lighter gameplay-focused project to test editor load, play mode behavior, and basic runtime performance.

I measured the first load, because the first launch is usually the slowest. After Unity imports and prepares a project once, later launches can be significantly faster.

During this first load, memory usage was around thirteen to fourteen gigabytes, but this number needs context. OBS Studio was recording, macOS was running normally, and I forgot to close the browser. So this was not a perfectly clean memory baseline.

Even with that mistake, the machine stayed responsive. That tells us the unified memory and SSD were handling the pressure reasonably well.

Unity FPS Sample Load Time

The first full load of the Unity First Person Shooter sample took around:

2 minutes 50 seconds

That is not instant, but for a first project import and load, it is acceptable. The important detail is that first launch should not be treated as normal everyday opening speed. Unity often does a lot of project preparation the first time.

Unity FPS Sample Gameplay Performance

Once the project was running, gameplay performance was strong.

Frame rate started around:

130 FPS

and could spike much higher, sometimes into the two hundreds.

Input response felt clean and the project ran smoothly. But this result needs to be interpreted honestly. The FPS sample is not a heavy visual showcase. It uses relatively simple visuals and low-poly style assets. So yes, the frame rate is impressive, but it is not shocking.

During gameplay, memory usage stayed around fourteen to fifteen gigabytes with other apps still open.

Unity Test Two: High Definition Sample Project

The second test uses Unity’s High Definition sample project. This is a more demanding test because it is heavier visually and involves more background loading and shader work.

Before running this test, I closed the browser to get cleaner numbers.

Even then, memory usage still ended up around thirteen to fourteen gigabytes once the project was loading and preparing.

Unity HDRP Sample Load Behavior

The editor opened at around:

2 minutes 40 seconds

But that was not the real end of the load. Unity was still compiling shaders and processing work in the background.

This is an important detail. Editor window visible does not always mean the project is ready. For real workflow testing, you need to wait until the editor is actually usable and the background compilation has settled.

The full ready-to-test load time was a little over:

5 minutes

Unity HDRP Sample Gameplay Performance

In the High Definition sample, performance was still surprisingly usable.

Frame rate started around:

90 FPS

and often stayed around:

100 to 110 FPS

In heavier views, it could dip into the eighties.

That is a good result for a base model machine. It does not mean this Mac mini is suddenly a high-end workstation. It means the M4 base model can handle more than people might expect, as long as the project scope is realistic.

Memory Pressure and System Responsiveness

The most interesting part was memory behavior. Even in the heavier Unity sample, memory usage stayed under roughly thirteen gigabytes in my run, and memory pressure stayed under control.

That matters because this machine only has sixteen gigabytes of unified memory. There is not a huge safety margin. If memory pressure goes bad, performance can collapse quickly.

In these Unity tests, the system stayed usable. That is a strong sign for small to medium game development workflows.

Comparison with Unreal Engine on the Same Mac mini M4

The Unreal comparison comes from my previous benchmark on the same Mac mini M4 base model.

For the simple first-person style test, Unreal loaded much faster:

Unreal simple scene load: around 20 seconds
Unity FPS first load: around 2 minutes 50 seconds

On frame rate, Unity performed higher in the simple sample. But that is not the whole story. Unreal’s baseline scene was also pushing noticeably better visuals. The geometry looked more detailed and the scene felt more visually polished.

So judging only by FPS would be lazy. You need to look at what each engine is rendering.

Heavy Project Comparison: Unity HDRP vs Unreal

The heavier comparison is not perfectly fair because the Unreal scene tested previously was heavier than Unity’s High Definition sample.

Still, Unreal loaded faster in that earlier heavy test, around:

4.5 minutes

compared to Unity’s full ready state at just over:

5 minutes

In the heavier Unreal scene, frame rate was lower, around the mid twenties to around forty. But that scene was also running more realistic lighting and a denser setup.

With quality adjustments, the Unreal project could be pushed much higher, even into the seventies and eighties.

Unity vs Unreal on Mac mini M4: Who Wins?

There is no clean winner here, and pretending otherwise would be nonsense.

Unity looks strong in simple and moderately heavy samples, especially in raw FPS. Unreal looks strong in load speed and visual quality relative to what it is rendering. Memory usage ends up in a similar range for both engines.

The better engine depends on what you are building.

• Unity makes sense for lighter projects, mobile games, stylized games, fast iteration, and workflows where high FPS on modest hardware matters.
• Unreal Engine makes sense for high-end visuals, realistic lighting, cinematic environments, and projects where the engine’s rendering stack gives you more out of the box.

The real winner in this test is the Mac mini M4 itself. For around six hundred dollars, this level of game development performance is impressive.

Should You Use the Base Mac mini M4 for Game Development?

Yes, but with realistic expectations.

The base Mac mini M4 can handle Unity and Unreal development better than many people expect. It is usable for learning, tutorials, small projects, medium projects, prototyping, mobile development, and even some heavier scene testing.

But do not fool yourself. Sixteen gigabytes of unified memory is not infinite. If you are working on huge Unreal worlds, massive assets, Nanite-heavy environments, giant Unity HDRP scenes, or running many tools at once, you will want more memory.

For serious long-term professional work, a higher-memory model gives you more headroom. For budget game development and learning, the base model is surprisingly capable.

Practical Takeaways

• The Unity FPS sample loaded in about two minutes and fifty seconds on first launch.
• The Unity FPS sample ran very smoothly, starting around one hundred thirty FPS and sometimes going much higher.
• The Unity High Definition sample took a little over five minutes to become fully ready.
• The HDRP sample often ran around ninety to one hundred ten FPS, with dips into the eighties in heavier views.
• Memory usage stayed around thirteen to fifteen gigabytes depending on the test and open apps.
• Unreal loaded faster in the tested simple scene, but Unity showed higher FPS in its simpler sample.
• Both engines are usable on the Mac mini M4 base model, but they have different tradeoffs.

Final Verdict

The base Mac mini M4 is not a toy. It is a genuinely capable entry-level game development machine if your expectations are sane.

Unity runs well on it. Unreal runs well on it. Neither result means you should treat it like a high-end workstation. But for the price, the performance is strong.

If you are learning game development, building small to medium projects, testing engine workflows, or creating tutorials, this machine is more than usable. If you are building massive scenes or professional-scale 3D productions, get more memory. Do not cheap out and then complain later.
