Supported Devices

The OpenVINO runtime can infer various models of different input and output formats. Here, you can find configurations supported by OpenVINO devices, which are CPU, GPU, or GNA (Gaussian neural accelerator coprocessor). Currently, 11th generation and later processors (currently up to 13th generation) provide a further performance boost, especially with INT8 models.

Note

With OpenVINO™ 2020.4 release, Intel® Movidius™ Neural Compute Stick support has been cancelled.

The OpenVINO Runtime provides unique capabilities to infer deep learning models on the following device types with corresponding plugins:

Intel Processor Graphics, including Intel HD Graphics and Intel Iris Graphics

CPU plugin

Intel Xeon with Intel® Advanced Vector Extensions 2 (Intel® AVX2), Intel® Advanced Vector Extensions 512 (Intel® AVX-512), and AVX512_BF16, Intel Core Processors with Intel AVX2, Intel Atom Processors with Intel® Streaming SIMD Extensions (Intel® SSE)

VPU plugin (available in the Intel® Distribution of OpenVINO™ toolkit)

Intel® Neural Compute Stick 2 powered by the Intel® Movidius™ Myriad™ X, Intel® Vision Accelerator Design with Intel® Movidius™ VPUs

GNA plugin (available in the Intel® Distribution of OpenVINO™ toolkit)

Intel Speech Enabling Developer Kit, Amazon Alexa* Premium Far-Field Developer Kit, Intel Pentium Silver J5005 Processor, Intel Pentium Silver N5000 Processor, Intel Celeron J4005 Processor, Intel Celeron J4105 Processor, Intel Celeron Processor N4100, Intel Celeron Processor N4000, Intel Core i3-8121U Processor, Intel Core i7-1065G7 Processor, Intel Core i7-1060G7 Processor, Intel Core i5-1035G4 Processor, Intel Core i5-1035G7 Processor, Intel Core i5-1035G1 Processor, Intel Core i5-1030G7 Processor, Intel Core i5-1030G4 Processor, Intel Core i3-1005G1 Processor, Intel Core i3-1000G1 Processor, Intel Core i3-1000G4 Processor

Arm® CPU plugin (unavailable in the Intel® Distribution of OpenVINO™ toolkit)

Raspberry Pi™ 4 Model B, Apple® Mac mini with M1 chip, NVIDIA® Jetson Nano™, Android™ devices

Multi-Device execution

Multi-Device execution enables simultaneous inference of the same model on several devices in parallel

Auto-Device plugin

Auto-Device plugin enables selecting Intel device for inference automatically

Heterogeneous plugin

Heterogeneous execution enables automatic inference splitting between several devices (for example if a device doesn’t support certain operation ).

Note

ARM® CPU plugin is a community-level add-on to OpenVINO™. Intel® welcomes community participation in the OpenVINO™ ecosystem, technical questions and code contributions on community forums. However, this component has not undergone full release validation or qualification from Intel®, hence no official support is offered.

Devices similar to the ones we have used for benchmarking can be accessed using Intel® DevCloud for the Edge, a remote development environment with access to Intel® hardware and the latest versions of the Intel® Distribution of the OpenVINO™ Toolkit. Learn more or Register here.

Supported Configurations

The OpenVINO Runtime can inference models in different formats with various input and output formats. This page shows supported and optimal configurations for each plugin.

Terminology

Acronym/Term

Description

FP32 format

Single-precision floating-point format

BF16 format

Brain floating-point format

FP16 format

Half-precision floating-point format

I16 format

2-byte signed integer format

I8 format

1-byte signed integer format

U16 format

2-byte unsigned integer format

U8 format

1-byte unsigned integer format

NHWC, NCHW, and NCDHW refer to the data ordering in batches of images:

  • NHWC and NCHW refer to image data layout.

  • NCDHW refers to image sequence data layout.

Abbreviations in the support tables are as follows:

  • N: Number of images in a batch

  • D: Depth. Depend on model it could be spatial or time dimension

  • H: Number of pixels in the vertical dimension

  • W: Number of pixels in the horizontal dimension

  • C: Number of channels

CHW, NC, C - Tensor memory layout. For example, the CHW value at index (c,h,w) is physically located at index (c*H+h)*W+w, for others by analogy.
