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

Cortex-A520 is a high-efficiency, top-performing Armv9.2 CPU providing improved power efficiency tuned to background and lightweight workloads for increased battery life and scalability across the consumer technology market. It comes along with new DSU-120 and is compatible with Cortex-X4 and Cortex-A720 for building big.LITTLE clusters. This is the second LITTLE CPU generation to be 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.
“Efficiency First” Design Philosophy

Microarchitecture improvements keep efficiency first 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.
