UL Procyon AI Inference Benchmark for Android devices

Machine learning is powering exciting new features in mobile apps. Many smartphones now have dedicated hardware to accelerate the computationally intensive operations required for on-device inferencing.

Today, we’re launching the UL Procyon AI Inference Benchmark, a new test for measuring the performance and accuracy of dedicated AI-processing hardware in Android devices.

The benchmark uses a range of popular, state-of-the-art neural network models such as MobileNet V3, Inception V4, SSDLite V3 and DeepLab V4. The models run on the device to perform common machine-vision tasks. The benchmark measures performance for both float- and integer-optimized models.

The benchmark runs on the device's dedicated AI-processing hardware, with the Android Neural Networks API (NNAPI) selecting the most appropriate processor for each test. The benchmark also runs each test separately on the GPU and/or CPU for comparison. 

UL Procyon benchmarks are designed for professional users. The AI Inference Benchmark is for hardware and software engineers who need independent, standardized tools to test the quality of their NNAPI implementations and the performance of dedicated AI hardware in Android devices.

Results and insights

The UL Procyon AI Inference Benchmark provides a range of useful results, metrics and insights. Use the main benchmark score to compare the AI performance of Android devices. The score breakdown helps you compare the performance and quality of different processors with integer and float models. The in-app ranking list shows you how a device compares with other smartphones.

A chart for each test shows the inference time with NNAPI and other processors, making it easy to see the difference in performance. A hardware monitoring chart shows you how the device’s temperature, battery charge level and memory use changed during the benchmark run. You can also check the outputs from each model to ensure the hardware is returning the correct results.

The UL Procyon AI Inference Benchmark is easy to install and run with no complicated configuration required. You can start the benchmark on the device or via ADB. You can view benchmark scores, charts and rankings in the app and export detailed result files for further analysis.

Available now

The UL Procyon AI Inference Benchmark is available now. Site licenses for professional users start at $1,495 (USD) per year.
