Arm introduces Cortex-A925: a new processor core for mobile phones

Arm introduces a new reference design for a powerful mobile computing core: the Cortex-A925. Manufacturers like MediaTek will use this design to develop their chipsets. The ARM specialist is also showing off a new GPU.

Arm is launching a new high-end CPU design to the world and is also launching a new graphics processing unit (GPU) design. Arm designs have traditionally been used as a blueprint by ARM processor manufacturers such as MediaTek, Samsung, and Google. So the new designs will appear in mobile CPUs tomorrow.

Central processing units

First and foremost, the Arm Cortex-X925 processor core. This chip will be 36 percent more powerful at peak performance on a single core. AI performance also improves by 46 percent. Processors have up to three megabytes of L2 cache per core. The design focuses on the 3nm baking process. This CPU core is designed for peak performance.

Arm simultaneously launches the younger brother Cortex X-A725. It should be a little more efficient. Finally, the Cortex-A520 is an entry-level budget model. In practice, CPU designers will mix performance and efficiency cores as desired in their designs. Arm states that with these new chips, it’s possible to cram up to fourteen cores onto a single chip.

Graphics processing units

Additionally, Arm is sharing a new GPU design: the Immortalis-G925. This graphics component should be 37 percent stronger than its predecessor for those who like to play games, and 34 percent stronger for AI workloads. Arm has made several improvements to the GPU architecture, which is also optimized for the 3nm process.

In addition to the Immortalis GPU, Arm is also launching the Mali-G725 and Mali-G625: two additional user-friendly designs. CPU manufacturers can integrate CPU and GPU schematics into their SoCs to power smartphones, with or without their own innovations.

Not all ARM chips are based on Arm schematics, although they often serve as the basis. For example, Qualcomm builds its own Kryo cores, but they are derived from Arm designs. Apple uses self-developed M cores for its laptops, which are compatible with the broader ARM architecture.
