ARM Cortex-A725 is ARM’s high-performance CPU core introduced in 2024. It succeeds the Cortex-A720 and can be used as either a “big” or “LITTLE” core in ARM’s heterogenous CPU designs, typically paired with other cores like the high‑performance Cortex-X925 or the efficiency-focused Cortex-A520.

Key points
- Efficiency and performance: about 25% better efficiency, roughly 12% higher peak performance, and about 20% improvement in L3 cache traffic. It also doubles the L2 cache size and features an improved DSU-120.
- Architecture: part of the Cortex‑A family built on ARMv9.2‑A, with the Cortex-A725 as its microarchitecture. Each core includes L1 data and instruction caches (64/128 KiB total, with I-cache of 32/64 KiB with parity), 128 KiB–1 MiB of L2 cache per core, and optional L3 cache (256 KiB–32 MiB).
- Code name and variant: product code named “Chaberton,” with a variant that sits alongside the Cortex-X925. Predecessor is Cortex-A720; successor is ARM C1-Pro.
- Usage: practical deployments include Google’s Tensor G5 in the Pixel 10 series, MediaTek’s Dimensity 8400, Samsung’s Exynos 2500, and Xiaomi’s Xring O1.
