An evolution for mobile graphics

At Imagination, we are continuing to enhance the graphics performance of our GPUs and boost visual quality with ray tracing. IMG DXT is Imagination’s groundbreaking ray-tracing GPU that scales to unlock cutting-edge graphics for all mobile device users, delivering even greater performance levels and power efficiency while bringing affordable and usable ray tracing into the mainstream.

IMG DXT provides everything a customer might need in a GPU to integrate into their next-generation, game-ready mobile devices. Download our white paper to learn more about our PowerVR Photon, the world’s first mobile-optimised ray tracing architecture, and the new features introduced in DXT.

Scalable ray tracing

IMG DXT offers ray tracing in several configurations and performance points using its ray acceleration cluster (RAC). This means that manufacturers looking to deliver a ray-tracing capable device at a lower cost can take a half-RAC per SPU to provide the ultimate mobile visual experience. IMG DXT offers single, dual, triple and quad-RAC configurations.

Compared to our previous generation with the same configuration, IMG DXT delivers usable ray tracing at up to 40% lower area cost.

Ray tracing – more accessible than ever

Ray tracing on DXT is made more accessible thanks to fragment shading rate and 2D dual-rate texturing that frees up additional performance.

Fragment shading rate and ray tracing – a perfect partnership

Thanks to Fragment Shading Rate (FSR), IMG DXT frees up performance headroom for developers. FSR decreases the number of fragments processed and significantly increases graphics performance with minimal impact on visual quality. FSR makes ray-traced effects more efficient as fewer rays are sent into the scene.

This means realistic lights and shadows are achievable with a smaller silicon area so developers can make the best use of ray tracing, even with half or single–RAC configurations. Developers can choose how aggressively they use FSR and balance how games use the hardware to deliver the best visual experience.

2D Dual-Rate Texturing

Many cutting-edge games rely on texture-sampling heavy filter effects. IMG DXT GPUs have a special mode inside their texture processing unit (TPU) that detects these algorithms and doubles their execution rate.

This result of this “fast path” for post-processing effects is a doubling of bilinear filtering performance, which can be used for tasks such as image processing, or advanced ray tracing.

What our partners are saying

Rui Li, Technical Expert

“Ray tracing is revolutionising immersion, enabling developers to create graphically compelling games that offer users unique visual experiences every time they play. A key challenge for mobile gaming is packing all that processing power into a small area of silicon. Imagination has spearheaded the ray tracing revolution for mobile devices, and we’re excited for the launch of the new DXT GPU, which scales the PowerVR architecture to lower silicon footprints for maximum graphical output. We will continue working closely with Imagination to shape the future of mobile gaming.”

Hansen Hong, Director of Software Technology Planning

“Imagination is a partner of OPPO in O3DF’s Mobile Device Working Group and we are working closely together to optimise performance for next-gen GPU architectures. IMG DXT brings new opportunities to integrate market-leading, realistic graphics across smartphone ranges, unlocking ray tracing and FSR for more mobile gamers. We look forward to working with Imagination on building out the O3DE mobile renderer and enabling developers to take full advantage of this game-changing, open-source technology.”

Level up with DXT

Not all ray tracing solutions are the same.

Our Photon-architecture-based design is the only ray tracing architecture on the market that sits at Level 4 on the Ray Tracing Levels System (RTLS). Which means it delivers its market-leading visuals in the most power-efficient manner available in the industry.

With DXT, mobile gamers will get a powerful GPU that delivers the highest quality alongside great battery life.

Advanced software support

Imagination continues to offer optimal performance for its GPU products with its award-winning PowerVR SDK and developer tools.

The DDK enables ray tracing capabilities across the stack – with Vulkan RT support included. DXT includes support for a wider range of compression technologies to maximise bandwidth efficiency. This includes Khronos ASTC HDR, enabling textures to have a greater dynamic range between bright and dark areas, while retaining detail.
