ARM announces Immortalis GPU today

Includes ray tracing on mobile

ARM is announcing its new flagship Immortalis GPU today, its first to include hardware-based ray tracing on mobile.

Immortalis-G715 is designed to be the ARM’s first GPU to deliver the same on Android phones and tablets.

Built on top of the Mal GPU, Immortalis is designed with 10-16 cores and can manage a 15 per cent boost over the previous generation premium Mali GPUs. Immortalis is the start of a transition to ray tracing on mobile following its success with the 8 billion Mali GPUs that have shipped to date.

ARM product management director Andy Craigen said the Ray Tracing techniques can use significant power, energy, and area across the mobile system-on-a-chip (SoC).
"However, Ray Tracing on Immortalis-G715 only uses four per cent of the shader core area, while delivering more than 300 percent performance improvements through the hardware acceleration."

It's unclear if a three times speedup over software-based ray tracing will be enough to tempt game developers, but when Nvidia introduced hardware accelerated ray tracing in its RTX 2080, it advertised a 2x-3x boost at the time.

Arm's Paul Williamson, said that it may also come in handy in augmented reality applications where RT could be used to match virtual lighting to the real-world environment around you.

Arm is already delivering software-based ray tracing in last year's Mali-G710, but the promise of hardware support means we will start to see flagship smartphones with this chip at the beginning of 2023. Samsung also announced its Exynos 2200 chip with hardware-based ray tracing earlier this year, so manufacturers are getting ready for the games to arrive.
