Arm Unveils Cortex-X925 CPU and Immortalis G925 GPU

Arm introduces Cortex-X925 CPU and Immortalis G925 GPU, enhancing smartphone performance with significant boosts in AI and graphics capabilities.

On May 29, Arm announced the next generation of CPU and GPU designs for flagship smartphones: the Cortex-X925 CPU and Immortalis G925 GPU. These successors to the Cortex-X4 and Immortalis G720, used in MediaTek’s Dimensity 9300 processor, promise substantial performance upgrades.

Arm has updated the naming scheme for the Cortex-X CPU series to highlight the significant performance improvements. The X925 delivers 36% higher single-core performance compared to the X4, as measured by Geekbench tests.

Thanks to up to 3MB of private L2 cache, the X925 also boasts a 41% improvement in AI workload performance, measured by “time to token.”

The Cortex-X925 introduces the new Cortex-A microarchitecture, featuring the Cortex-A725 and Cortex-A520 cores. The Cortex-A725 offers 35% better performance efficiency than its predecessor, the A720, while the Cortex-A520 improves energy efficiency by 15%.

The new Immortalis G925 GPU is touted as Arm’s most powerful and efficient GPU to date.

It achieves a 37% improvement in graphics performance, a 52% increase in ray-tracing capability, a 34% boost in AI and machine learning workloads, and a 30% reduction in power consumption compared to the previous generation G720.

Additionally, Arm has introduced an “optimized layout” for these new CPU and GPU designs, simplifying integration for device manufacturers.

This new physical implementation solution aims to accelerate the market release of devices featuring the Cortex-X925 and Immortalis G925.

Arm expects the first smartphones with these new designs to be available by the end of 2024. MediaTek’s Vice President, JC Hsu, confirmed that the upcoming Dimensity 9400 chipset will incorporate the latest Armv9 Cortex-X925 CPU and Immortalis-G925 GPU.
