Side-by-side simulation · recommended settings

Direct comparison of local LLM equipment creation speeds

Start the same model at the same moment and check the difference not only in the numbers but also in the speed at which the actual answer is delivered.

Which one fits my needs?

Answer completion

RTX 5090 32GB

At the estimate midpoint, it finishes the same answer about 21.0× faster.

Input processing

RTX 5090 32GB

The estimated input-processing midpoint is higher at 13,161 tok/s.

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 / vLLM 0.28.0 · CUDA 13.3.1 · driver 610.43.02 · MTP-2. When runtime paths differ, the speed gap also includes software and model-format differences.

Estimated power draw

Mac mini M4 Pro 64GB

Estimated LLM power draw is lower at about 95 W. Noise and physical size need a separate check.

Local pricing

The Mac mini M4 Pro 64GB is a complete system, while the RTX 5090 32GB is a GPU-only unit. The GPU-only price should be compared after adding the base system cost.
