# Use of Multiple GPUs

Except under very narrow circumstances, using multiple GPUs in a single system will not reduce Deep Learning tool training or processing time. What multiple GPUs can do is the following:

- Increase system throughput when your application uses multiple threads to concurrently process images.
- Increase training productivity, by allowing you to train multiple tools at the same time.

Note: When you train or process two or more than two High Detail Green Classify Tools at same time, you don’t’ have advantages of using Multiple GPUs on that High Detail Green Classify Tools.
