UL Procyon® AI Inference Benchmark for Android
Benchmark AI performance and quality using NNAPI
Machine learning is powering exciting new features in mobile apps. Many devices now have dedicated hardware to accelerate the computationally intensive operations required for on-device inferencing. The Android Neural Networks API (NNAPI) provides a base layer for machine learning frameworks to access the dedicated AI processing hardware in a device.
The UL Procyon AI Inference Benchmark for Android measures the AI performance of Android devices using NNAPI. The benchmark score reflects both the speed and the accuracy of on-device inferencing operations. With the UL Procyon AI Inference Benchmark for Android, not only can you measure the performance of dedicated AI processing hardware in Android devices, you can also verify NNAPI implementation quality.
The benchmark uses a range of popular, state-of-the-art neural networks running on the device to perform common machine-vision tasks. The benchmark runs on the device's dedicated AI-processing hardware via NNAPI. The benchmark also runs each test directly on the GPU and/or the CPU for comparison.Buy now

Developed with industry expertise
UL Procyon benchmarks are designed for industry, enterprise and press use with tests and features created specifically for professional users. The AI Inference Benchmark for Android was designed and developed with industry partners through the UL Benchmark Development Program (BDP). The BDP is an initiative from UL Solutions that aims to create relevant and impartial benchmarks by working in close cooperation with program members.
Neural network models
MobileNet V3 is a compact visual recognition model that was created specifically for mobile devices. The benchmark uses MobileNet V3 to identify the subject of an image, taking an image as the input and outputting a list of probabilities for the content in the image. The benchmark uses the large minimalistic variant of MobileNet V3.
Inception V4 is a state-of-the-art model for image classification tasks. Designed for accuracy, it is a much wider and deeper model than MobileNet. The benchmark uses Inception V4 to identify the subject of an image, taking an image as the input and outputting a list of probabilities for the content identified in the image.
SSDLite MobileNet V3
SSDLite is an object detection model that aims to produce bounding boxes around objects in an image. SSDLite uses MobileNet for feature extraction to enable real-time object detection on mobile devices. In the benchmark, the float version of SSDLite uses the small minimalistic MobileNet V3 variant. The integer version uses the EdgeTPU variant of MobileNet V3.
DeepLab is an image segmentation model that aims to cluster the pixels of an image that belong to the same object class. Semantic image segmentation labels each region of the image with a class of object. The benchmark uses MobileNet V2 for feature extraction enabling fast inference with little difference in quality compared with larger models.
The benchmark includes a custom Convolutional Neural Network (CNN) based on the AlexNet architecture. It is designed to test the performance of basic CNN operations and is trained on randomly generated training data. It contains two Convolutional layers, which are followed by Max Pooling and Dropout layers, and one fully connected layer.
Integer and float models
The benchmark includes both float- and integer-optimized versions of each model. Each model runs in turn on all compatible hardware in the device. With NNAPI, the benchmark will use the device's dedicated AI-processing hardware, if supported. Float models use NNAPI or run directly on the CPU or GPU. Integer models use NNAPI or run directly on the CPU.
