# Estimating GPU Memory Usage

- Display: memory to store images prior to computation.
- VisionPro Deep Learning Reserved: memory reserved for computation.
- Free: memory left free, because the amount of memory used is not known.

An example for training:

- Reserved memory at 2.0GB (the minimal value for training)
- Free memory at about 1GB
- Which results in a graphics card with at least 3.5GB of memory

An example for runtime:

- Reserved memory at 512MB
- Free memory at about 256MB
- Which results in a graphics card with no minimal memory required
