High-Efficiency “LITTLE” Cortex CPU with Arm DynamIQ Technology 

Cortex-A520 is a high-efficiency, top-performing Armv9.2 CPU providing improved power efficiency and tuned to background and lightweight workloads for increased battery life and scalability across the consumer technology market. It comes with new Arm DSU-120 and is compatible with Arm Cortex-X925 and Arm Cortex-A725 for building big.LITTLE clusters. This is the second LITTLE CPU generation developed according to the Arm Total Compute strategy and addresses a wide range of consumer technology applications across mobile devices (premium to entry tiers), home electronics (DTVs and set-top boxes), and XR/wearables.

Features and Benefits

Significant Power Efficiency Improvements

Up to 22% power reduction compared to Cortex-A510, with up to 8% performance uplift, scalable across multiple segments. Cortex-A520 enables additional power efficiency improvements up to 15% with advance 3nm physical solutions.
Efficiency First Design Philosophy

Micro-architecture improvements keep efficiency first and foremost, and achieve top power efficiency for low intensity/background workloads to increase battery life.
Advanced Architecture Features

First AArch64-only CPU based on Armv9.2 architecture for secure consumer techologies and ML. New QARMA3 PAC algorithm lowers performance cost, strengthening PAC deployment in the consumer technology market.
