Imagination AI solution leads performance 2 times closest to competitors
**Introduction**
When it comes to AI acceleration, the expert knows what's best. Imagination Technologies' latest neural network accelerator, PowerVR 2NX NNA, is now delivering performance that’s twice as close to the competition as any other solution—whether it's based on DSP + hardware, VPU + hardware, or a dedicated neural network DSP. This makes it an ideal choice for HiSilicon’s next-generation Kirin chips, promising significant improvements in AI processing power and efficiency.
Artificial intelligence has become a strategic priority for nations around the world. As AI permeates key equipment across industries, it's becoming the core differentiator for smart devices. For example, Huawei has already outperformed Apple’s iPhone 8 using AI technology. The neural network processing unit that mimics human brain computing models is set to be the top choice for future machine learning and deep learning applications.
Chris Longstaff, Senior Director of Product and Technology Marketing at Imagination, said: “Considering power, bandwidth, performance, reliability, security, and latency, the next generation of AI devices will not rely solely on software or cloud computing. Hardware-based solutions for machine learning and deep learning are essential. Neural networks will soon become the key processing unit in AI SoCs, just like CPUs and GPUs.â€

Neural networks, such as CNNs, RNNs, and LSTMs, are driving major advancements in AI industries. Imagination, a leading GPU IP provider, recently launched a complete, standalone hardware IP neural network accelerator in Shenzhen. This new solution leverages the PowerVR architecture to deliver industry-leading performance, power, and area efficiency.
Chris Longstaff added: “The PowerVR 2NX NNA offers performance, power, and area efficiency that is two times closer to the competition than any other solution, regardless of whether the competitor uses DSP + hardware, GPU + hardware, or a neural network DSP.â€
Today, companies developing SoCs for mobile, surveillance, automotive, and consumer systems can integrate high-performance computing with minimal power consumption and chip area using the PowerVR 2NX NNA.
For instance, modern drones flying at over 150 mph require real-time object detection and avoidance. Without hardware acceleration, collision avoidance would need a 10–15 meter range. With PowerVR 2NX NNA, this range can be reduced to less than 1 meter, allowing the drone to run multiple networks for object recognition and tracking simultaneously.
Another example: sorting 1,000 photos on a mobile device using a high-end CPU takes 60 seconds, but with PowerVR 2NX NNA, it only takes 2 seconds.
NNA is expected to become as essential as CPUs and GPUs. It has wide-ranging applications—from AR/VR headsets (feature detection, eye tracking) to automotive safety (pedestrian detection, driver alertness monitoring), intelligent surveillance (facial recognition, crowd behavior analysis), and more.
David Harold, Vice President of Marketing at Imagination, said: “PowerVR 2NX is specifically designed for mobile and Android platforms. It's the first dedicated neural network hardware solution with support for flexible bit widths from 16-bit to 4-bit and low bandwidth requirements.â€
According to the Embedded Vision Developer Survey, 79% of respondents have used or plan to use neural networks in their products. Imagination’s customers have already deployed NN-based systems in security, mobile, automotive, and set-top box markets.
Jeff Bier, founder of the Embedded Vision Alliance, stated: “Dedicated processors like PowerVR 2NX NNA are crucial for deploying powerful algorithms in various applications. They provide the performance needed while keeping cost and power under control.â€
With growing demand for neural networks, solutions like PowerVR 2NX NNA—offering 8x performance density over pure DSP—are set to redefine AI processing. They reduce power and cost while optimizing bandwidth usage, making them ideal for future AI SoCs.
