• Arm unveils Cortex‑A725, the next‑gen big core succeeding the A720 in the 2024 CSS. • A725 doubles L2 cache to 1 MiB, making it the widest and deepest big core yet. • Built on 3 nm, it incorporates register‑file and memory‑buffer optimizations for better PPA. • Supports Armv9.2 features: SME (SVE2), GEMM, and BFloat16 for AI workloads. • Integrated with DSU‑120, Cortex‑A520, and Cortex‑X925 in the 2024 Client Compute Subsystem. • Expected to deliver significant performance‑efficiency gains over the A720, boosting mobile and edge devices.

Article Summaries:

  • Arm unveiled its next‑generation high‑performance big core, the Cortex‑A725, as part of the 2024 Compute Subsystem (CSS). The A725 succeeds the Cortex‑A720 and runs on a 3‑nanometer process, featuring a 1 MiB L2 cache that doubles the predecessor’s capacity. Arm reports up to 35 % improvement in performance‑efficiency and 25 % higher peak performance on SPECint_base2017, thanks to architectural tweaks and larger L1/L2/L3 caches (64 K/1 MiB/16 MiB). The core is slated for inclusion in premium mobile devices by year‑end.
