Arm's new flagship GPU will include hardware ray tracing support. Yeah, ray-traced phones

pcgamer.com:

Hardware-based ray tracing is coming to mobile devices(opens in new tab). The Immortalis G715 is Arm's new flagship GPU. It promises a 15% performance uplift over the previous premium Mali GPU and up to a 300% improvement in ray tracing performance thanks to its dedicated hardware.

Details are fairly thin and Arm didn’t present any performance data, though it does plan to hold a webinar on August the 24th to quote: “Learn about the latest graphics features made possible by Immortalis-G715, including hardware-based ray tracing support for more realistic and immersive mobile gaming experiences.” We’ll learn more about Arm’s RT implementation then.

Arm is introducing two new Mali GPUs alongside the 10-core Immortalis. These are the Mali-G715 with 7 to 9 cores and the Mali-G615 with up to 6 cores.

All of the new GPUs support variable rate shading. With VRS, the GPU can allocate resources to more complex parts of the image while rendering less important part of the image with lower fidelity, such as an object in the far background or out of focus. Alongside other architectural improvements, Arm believes the new GPUs will deliver at least a 15% performance improvement over previous generation GPUs.
