Intel Neural Compute Stick 2

The Intel Neural Compute Stick 2 is a compact USB-based accelerator designed for deploying deep learning inference models on edge devices with minimal power consumption and latency. Machine learning engineers, roboticists, and embedded systems developers use this device to prototype and deploy computer vision, natural language processing, and real-time inference applications without requiring high-end GPUs or cloud connectivity. It solves the critical problem of running complex neural networks locally on resource-constrained devices while maintaining real-time performance and data privacy.

Product Overview

The Intel Neural Compute Stick 2 leverages Intel's Movidius Myriad X Vision Processing Unit (VPU) to deliver specialized hardware acceleration for deep learning inference workloads. The device connects via USB 3.0 interface and operates independently without requiring additional power connections, making it ideal for portable and embedded applications. The Myriad X VPU features 16 specialized SHAVE processors and dedicated neural compute engines that can execute optimized convolutional neural networks, object detection models, and pose estimation algorithms with significantly lower latency compared to CPU-only inference.

What distinguishes the Neural Compute Stick 2 is its exceptional power efficiency, consuming less than 1.5 watts during operation while delivering throughput comparable to discrete GPUs in many inference scenarios. The device supports OpenVINO toolkit, Intel's optimized inference framework, which enables developers to convert trained models from popular frameworks like TensorFlow, PyTorch, and Caffe into optimized intermediate representations. This architecture makes it particularly valuable for autonomous robotics, drone applications, industrial IoT gateways, and edge AI deployments where power consumption, thermal management, and physical space are critical constraints.

How to Use

Begin by installing the OpenVINO toolkit on your host system (Windows, Linux, or macOS), which includes the Model Optimizer for converting trained neural networks into optimized intermediate representations compatible with the Myriad X hardware. Connect the Intel Neural Compute Stick 2 to a USB 3.0 port on your host device or edge platform like Raspberry Pi 4, Jetson Nano, or x86 industrial computer. Install the necessary drivers and inference engine components, then use the OpenVINO Python API or C++ inference engine to load your optimized model and execute inference on the accelerator.

For optimal performance, quantize your models to INT8 precision using OpenVINO's post-training optimization tools, which reduces model size and increases throughput while maintaining inference accuracy within acceptable margins. Start with pre-trained models from Intel's model zoo to understand the workflow, then gradually transition to custom-trained models. Monitor inference latency and throughput using OpenVINO's profiling tools to validate that your deployment meets real-time requirements. The device automatically manages memory allocation and compute scheduling, but understanding batch processing capabilities and model input preprocessing will maximize the stick's 4 TOPS computational capacity for your specific application.

Frequently Asked Questions

What is the difference between Intel Neural Compute Stick 2 and the original Neural Compute Stick?

The Neural Compute Stick 2 features the Movidius Myriad X VPU compared to the original Myriad 2, delivering approximately 10x higher throughput at 4 TOPS versus 0.4 TOPS. It also supports OpenVINO toolkit optimization, provides better INT8 quantization support, and offers improved power efficiency. The Myriad X architecture includes dedicated neural compute engines specifically designed for convolutional operations, making it significantly more efficient for modern deep learning models.

Can I use the Neural Compute Stick 2 with Raspberry Pi and what are the performance expectations?

Yes, the stick works excellently with Raspberry Pi 4 Model B connected via USB 3.0. Performance varies based on model complexity, but typical use cases achieve 15-30 FPS for single-stream object detection models like MobileNet-SSD and 5-10 FPS for more complex models like Faster R-CNN. The Raspberry Pi CPU handles preprocessing and postprocessing while the stick accelerates the neural network inference, resulting in significantly better throughput than CPU-only inference. For multi-stream video processing, the stick can handle 2-4 concurrent streams depending on model size and complexity.

What model formats and frameworks does the Neural Compute Stick 2 support?

The stick supports any model that can be converted to OpenVINO Intermediate Representation format. This includes TensorFlow (frozen graphs and SavedModel format), PyTorch (via ONNX), Caffe, MXNet, and Kaldi models. You must use the OpenVINO Model Optimizer to convert your trained model into the .xml and .bin intermediate representation files. The toolkit also supports post-training optimization including INT8 quantization, which is recommended for maximum throughput on the Myriad X hardware.

What is the maximum model size that can be deployed on the Neural Compute Stick 2?

The stick has 512 MB of on-chip SRAM for model weights and activations. After accounting for system overhead, approximately 450-480 MB is available for neural network models. Most modern efficient architectures like MobileNet, SqueezeNet, and quantized ResNet variants fit comfortably within this constraint. Larger models like full ResNet-50 or VGG require INT8 quantization to fit. For models exceeding available memory, you can use model partitioning techniques or deploy multiple sticks for parallel inference across model segments.
