Arm Immortalis Flagship GPU Includes Hardware-Based Ray Tracing

Arm has announced a new GPU family, targeting ultimate gaming experiences on next-gen flagship smartphones. The first of its new 'beyond-Mali' breed is the Immortalis-G715, and it comes with a sizable and realistically lit feather in its cap. It's "the first Arm GPU to offer hardware-based ray tracing support on mobile." Immortalis won't replace Mali graphics, though, and this is evidenced by Arm announcing two new Mali GPUs today, with many advanced graphical quality and performance features.

It's interesting to see Arm launching hardware accelerated ray tracing on mobile, at a time when even beefy desktop PCs with GPUs eating hundreds of watts require complementary technologies such as DLSS and FSR for the sake of frame rates and responsiveness. There are some technologies available for Arm GPUs that might help boost frame rates, though. Immortalis and new Mali GPUs both support Variable Rate Shading (VRS) and Adaptive Performance in Unity titles, for example. Additionally, the new GPUs from Arm are all said to offer 15% better rasterization performance and improved efficiency compared to the previous generation.

[...] Interestingly, Arm says that the ray tracing hardware in the Immortalis GPU only uses 4% of the shader core area, while delivering more than a 300% performance improvement through the hardware acceleration.

Press release.
