PowerVR Series3NX


The highest performance neural network inference accelerator

Neural networks are the established software tool for complex signal processing and pattern recognition that lie behind many AI technologies. PowerVR Series3NX is the fastest, most power-efficient embedded solution for hardware acceleration of neural networks on the market. Thanks to key architectural enhancements the Series3NX benefits from a 40% performance boost over the previous generation, performing up to 10 tera operations per second (TOPS) from a single core, providing the highest performance density per mm2 in the market.

Bringing multi-core scalability to the embedded AI market

Thanks to the scalability of PowerVR Series3NX architecture, multi-core implementations can achieve up to 160 TOPS, enabling ultra-high performance for the most demanding applications. Series3NX will be available in a variety of offerings, enabling SoC manufacturers to meet a range of design targets to address multiple markets and applications.

Neural network acceleration for edge devices

As neural networks drive an explosion in technological progress across industries, NNAs are now a fundamental class of processor, as significant as CPUs and GPUs. By integrating a PowerVR Series3NX Neural Network Accelerator (NNA) manufacturers can build devices that offer high-performance computation of neural networks at very low power consumption, in minimal silicon area. Offering this processing in edge devices removes the limitations of the cloud, such as bandwidth constraints, latency issues and privacy concerns.

Flexible bit-depth data type support

As a fully flexible solution, the Series3NX supports neural network bit depths from 16 down to 4-bit, reducing bandwidth and increasing performance without compromising inference accuracy.

Lossless weight compression

Complementing its low-bit depth support, the Series3NX introduces a new lossless weight compression scheme that reduces network model sizes and bandwidth thus increasing overall performance.

Advanced security enablement

PowerVR Series3NX integrates with the industry-leading security architectures including a flexible infrastructure that enables integration into custom solutions, enabling rights holders to protect their content where required.

Leading performance with low power consumption

With the industry’s highest inference/mW, the Series3NX delivers class-leading neural network acceleration with the lowest power consumption.

Introducing PowerVR Series3NX-F

The Series3NX-F brings programmable extensibility to the Series3NX architecture. It combines a Series3NX core with a neural network programmable unit (NNPU); a highly neural network optimised GPGPU, based on our industry-proven Rogue architecture. This provides developers with even greater flexibility in optimising their applications to run on the Series3NX architecture.

Putting the smart in smartphone

In mobile devices where a GPU is mandated, device manufacturers can pair a PowerVR Series9XE/XEP or 9XM/9XMP GPU with the Series3NX NNA in the same silicon footprint as a competing standalone GPU. Machine learning is now deployed in a wide variety of mobile applications, such as face recognition and verification, object recognition, image enhancement, style transfer and music tagging to name but a few. To support this, our Series3NX NNA cores deliver a paradigm shift in performance, while simultaneously reducing battery consumption over pure GPU solutions.


Security and surveillance

PowerVR Series3NX NNA cores enable a new class of smart camera that perform high-performance neural network-based analytics for a wide range of verticals such as commercial and home surveillance, retail analytics and drones. It supports classic use cases such as number/license plate recognition, person/object recognition, behaviour detection and perimeter defence.


Automotive (ADAS)

Convolutional neural networks (CNNs) are playing a crucial role in developing self-driving cars. The Series3NX NNAs will power advanced driver-assistance systems (ADAS) including driver alertness monitoring, driver gaze tracking, seat occupancy, road-sign detection, drivable path analysis, road user detection and driver recognition.


Augmented and Virtual reality

Neural network hardware acceleration will be critical to fulfil the potential of next-gen augmented and virtual reality use cases. Scene understanding will enhance augmented reality, while movement analysis, eye tracking and gesture recognition will provide context awareness in virtual reality to provide the best possible relative user experiences.

PowerVR Series3NX cores

The PowerVR Series3NX builds on our experience creating the groundbreaking PowerVR Series2NX neural network accelerator. The Series3NX range of cores, created from a single scalable architecture, delivers high-performance, low-power neural network acceleration in the most area efficient way, to meet a wide range of customer needs.
