M5 Max MacBook Pro vs Mac Studio 128GB: Which for local LLMs?
This pair compares the same chip and memory. Decide whether you need portable use or a desk-based server, then add the peripherals you need to the machine price.

Image and video generation
Check the media model
LLM speed does not tell you media-generation performance. Choose the image or video model and resolution separately.
Runtime
Settings for your hardware
MLX 4-bit / MLX 4-bit. When runtime paths differ, the speed gap also includes software and model-format differences.
Estimated power draw
MBP M5 Max 128GB
Estimated LLM power draw is lower at about 120 W. Noise and physical size need a separate check.
Local pricing
Studio M5 Max 128GB is about 155 × KRW 10,000 cheaper based on the median price. If the speeds are similar, the cheaper one is the balancing choice.
Before choosing hardware
| Measure | MBP M5 Max 128GB | Studio M5 Max 128GB |
|---|---|---|
| Available fast memory | 114GB | 114GB |
| Memory bandwidth | 614GB/s | 614GB/s |
| Estimated total time | 8.4 seconds | 8.4 seconds |
| Estimated sustained LLM load | about 120W | about 165W |
| Korean price range (KRW) | 1,141–1,141 × KRW 10,000 | 922–1,050 × KRW 10,000 |
Estimated ranges for one user. Multi-GPU and multi-device results depend on the runtime and interconnect.
Choose local laptop use or connecting to a server
A MacBook Pro can run files directly while travelling. A Mac Studio server can accept requests from apps on other devices, but remote access and authentication need preparation. Decide first whether you need offline use away from home or access from several devices at home.
Check cooling and power with long-running work
A few short questions and keeping a model active for hours impose different demands. Consider placement, ambient temperature and concurrent work. Compare response speed and sustained power here; check long-session noise and temperature on the actual configuration.
Include display and input-device costs
The MacBook Pro includes a display and keyboard. A new Mac Studio setup may need a monitor, keyboard and mouse. Costs differ for someone with peripherals and someone building from scratch. List what you actually need rather than comparing machine prices alone.
