The Arm Immortalis-G925 represents a major evolution in mobile GPU technology, ushering in a new era of high-performance graphics and artificial intelligence (AI) performance for flagship devices. Built on Arm’s 5th-generation GPU architecture, Immortalis-G925 is Arm’s most powerful and efficient GPU to date, pushing advancements in gaming visuals, ray tracing, and AI workloads while simultaneously reducing power consumption compared to prior generations.
What Is Immortalis-G925?
Arm’s Immortalis line sits at the top tier of its GPU offerings—above the Mali family—with hardware support for advanced features such as ray tracing. The Immortalis-G925 is designed specifically for flagship mobile SoCs, targeting premium smartphones, tablets, and other high-performance, power-sensitive applications
Key architectural enhancements include:
Fragment prepass – reduces redundant rendering work to improve efficiency.
Doubled tiler and shift-convert throughput – accelerates geometry and shading workloads.
Improved command stream frontend – optimizes job dispatch to shader cores.
Enhanced ray tracing performance – facilitates realistic lighting and effects.
Scalable configurations – supports up to 24 GPU cores to suit diverse performance points.
These architectural changes help balance peak performance and sustained efficiency, a key challenge in thermal-limited smartphone environments. Unlike solutions that chase peak scores only to throttle quickly under load, G925’s design focuses on delivering consistent real-world gaming performance over longer sessions.
Performance Gains: Gaming, Efficiency, and Beyond
Arm’s internal tests and industry analyses indicate that Immortalis-G925 delivers significant performance uplifts over its predecessor, the Immortalis-G720:
Graphics & Gaming
1) ~37 % higher overall graphics performance compared to Immortalis-G720.
2) Up to ~46 % average uplift in popular mobile games.
3) Standout game performance improvements include Genshin Impact (~49 %) and Roblox (~46 %).
4) 52 % better ray tracing performance with intricate scenes, enabling more realistic shadows, reflections, and lighting.
This makes Immortalis-G925 particularly attractive for mobile AAA gaming, where high frame rates and advanced visual effects are increasingly expected on flagship phones.
