Arm has announced a significant upgrade to its product line. This year, they are introducing a flagship Cortex-X925 core, a Cortex-A725 performance core, and a refreshed Cortex-A520 efficiency core. These cores are compliant with Arm v9.2 and form the basis of the company’s Compute SubSystems (CSS) for Client, previously known as Total Compute Solutions.
The Cortex-X925, Cortex-A725, and Cortex-A520 are expected to bring some of the biggest year-over-year increases in performance yet. The Cortex-X925 is being touted as “making the best even better”, with Arm boasting big improvements in both AI and regular IPC. The Cortex-A725 is being described as “the workhorse for power-efficient AI throughput”, promising a 35% more performance-efficient core with increased performance at the same power as the A715 from last year.
Arm is also introducing a new DynamIQ Shared Unit (DSU) and an improved GPU in the form of the Immortalis G925. For the first time, Arm is packaging these cores as a GDSII to be provided to OEMs. This file can be provided to a fabricator like TSMC or Samsung for immediate production, taking into account any specific quirks or features of the fabricator. This approach can improve the time to market for companies using these cores.
Despite Qualcomm switching to its own Oryon Arm-based cores for the Snapdragon 8 Gen 4, Arm expects MediaTek to continue using their cores. Qualcomm could potentially release a non-flagship SoC using a combination of these cores in the future.
