Detailed Comparison: NVIDIA DIGITS 6 vs DIGITS 5
Framework Support
- DIGITS 5: The main framework supported was Caffe, with only partial and experimental TensorFlow compatibility. This often resulted in fewer options for TensorFlow users.
- DIGITS 6: DIGITS 6 fully embraced TensorFlow, making it stable and efficient alongside Caffe. Users working with both frameworks could benefit from more flexibility and reliability from DIGITS 6.
Object Detection
- DIGITS 5: It provided basic tools for object detection but had cumbersome and error-prone workflows.
- DIGITS 6: Improved the object detection process by introducing bounding box annotation tools. This improvement saved time and reduced errors, making complex detection tasks smoother.
Semantic Segmentation
- DIGITS 5: Provided initial tools for semantic segmentation but did not offer advanced functionalities. Users needed to handle the pre-processing and post-processing steps manually.
- DIGITS 6: Improved the workflows of segmentation with built-in tools that eased and accelerated processing. Projects which involved pixel-level image labeling were more streamlined and efficient.
Training Tools and Visualization
Data Augmentation
Data augmentation plays a key role in training robust models by introducing variety into datasets.
- DIGITS 5: Limited to very basic options, such as resize and crop. It did not provide advanced methods of preparing datasets for real-world applications.
- DIGITS 6: Added advanced augmentation techniques, like color transformations, rotations, and flipping. Those features helped the models generalize much better, making the accuracy even higher in various environments..
Training Visualization
Keeping track of model performance during training is crucial.
- DIGITS 5: Provided basic graphs for loss and accuracy. While helpful, they lacked depth and interactivity.
- DIGITS 6: Delivered detailed, interactive visualizations, making it easier to monitor training and troubleshoot issues. Users could analyze progress in real-time with clear, actionable insights.

Performance and Compatibility
GPU and Hardware Optimization
Hardware compatibility is essential for efficient training.
- DIGITS 5: Designed for older GPUs like Kepler and Maxwell. It utilized CUDA 8.0 but struggled with newer hardware.
- DIGITS 6: Optimized for Pascal and Volta GPUs, offering faster and more efficient training. It supported CUDA 9.0, ensuring compatibility with the latest drivers and GPUs.
Custom Model Support
Flexibility in using custom models can make a tool stand out.
- DIGITS 5: Allowed custom models, but the setup process was manual and time-consuming.
- DIGITS 6: Simplified this process with better UI integration. Users could easily load, train, and test custom architectures without extensive manual configuration.
Processor Compatibility and Performance: DIGITS 6 vs. DIGITS 5
NVIDIA DIGITS 5 and DIGITS 6 are tools used to train deep learning models on NVIDIA GPUs. The main differences between them are:
- Support for Newer GPUs:
- DIGITS 5 works well with older GPUs like the NVIDIA Tesla P100 or GTX 1080 Ti.
- DIGITS 6 is designed to take full advantage of newer GPUs like the Tesla V100, which are faster and more powerful.
- Performance:
- DIGITS 6 is faster, especially on new GPUs, because it can use advanced features like “Tensor Cores” for quicker calculations.
- Software Compatibility:
- DIGITS 5 uses older software tools (CUDA 8.0).
- DIGITS 6 works with newer software (CUDA 9.0), which is faster and supports more features.
- Ease of Use:
