Arm unveils new Cortex-X925 and Cortex-A725 CPUs cores alongside 14-core Immortalis-G925 GPU
Arm has announced two new CPU cores for flagship smartphone APs. With Qualcomm pivoting to in-house Nuvia cores, they'll be found in high-end parts from MediaTek and Samsung. The core formerly known as Cortex-X5 has now been renamed to Cortex-X925. On the other hand, the Cortex-A725 succeeds last year's Cortex-A720. This time, there appear to be no new efficiency cores, but the new Cortex-A520 core is 15% more power efficient than last time.
Arm claims the Cortex-X925 cores deliver up to a 36% improvement in single-threaded performance, specifically Geekbench. It comes with the new Arm v9.2 architecture that is "designed for AI" and brings forth "double digit" IPC gains. As a result, it is up to 41% faster than the Cortex-X4 in Llama Q4. The CPU core can be allocated up to 3 MB of private L2 cache. Similarly, the Cortex-A725 is up to 35% more power efficient compared to the Cortex-A720. Overall improvements include 23% increased browsing speed, 25% additional gaming performance and 10% power saving when viewing videos.
Arm has also unveiled a new 14-core GPU alongside its new CPU cores: the Immortalis-G925. It offers a 37% performance uplift and 52/5 bump in raytracing prowess. Developers can now use Unreal Engine's Lumen to push the boundary of visual fidelity on mobile platforms. Whether or not this will help the Immortalis-G925 stand against the Adreno 830/Xclipse 950 remains to be seen.
