nRF54H20 vs EFR32MG24


Overview


The Nordic Semiconductor nRF54H20 and the Silicon Labs EFR32MG24 (Multiprotocol Gecko 24) serve overlapping but strategically distinct niches in the professional wireless SoC market. The EFR32MG24 is Silicon Labs' premium multi-protocol smart home SoC combining BLE 5.3, Thread, Zigbee, and Matter support with a dedicated AI/ML hardware accelerator, Secure Vault Mid security, and 1536 KB Flash — effectively Silicon Labs' answer to both the smart home's demand for protocol versatility and the edge computing demand for local intelligence. The nRF54H20 is Nordic's premium multi-core BLE 5.4 SoC excelling in BLE feature depth, processing performance, and power efficiency for BLE-centric applications.


Both are high-end, professional-grade chips. The comparison reveals a fundamental architectural trade-off: multi-protocol smart home breadth with AI acceleration versus deep BLE specialization with LC3 codec and Auracast." data-category="LE Audio">LE Audio capability.




Key Differences


    

  • AI/ML hardware accelerator: The EFR32MG24 integrates a dedicated AI/ML accelerator for edge inference — enabling wake word detection, occupancy classification, predictive maintenance, and gesture recognition without sending data to the cloud. The nRF54H20 has no dedicated ML accelerator; inference runs on application CPU cores, which is slower and less power-efficient for sustained inference.
    • 

  • Multi-protocol breadth: The EFR32MG24 supports BLE 5.3, IEEE 802.15.4 (Thread, Zigbee), and Matter across all transports simultaneously. The nRF54H20 focuses on BLE 5.4 and does not support Thread or Zigbee, limiting Matter participation to BLE commissioning only.
    • 

  • Flash capacity: The EFR32MG24 ships with up to 1536 KB Flash — providing ample space for multi-protocol BLE plus Thread stacks, OTA update images, application code, and ML model storage. The nRF54H20 also has generous on-chip memory for complex BLE firmware.
    • 

  • Secure Vault Mid: The EFR32MG24 includes Secure Vault Mid with certified tamper detection, hardware root of trust, and secure key management. Combined with Matter certification capability, it addresses the full smart home security stack including commissioning security attestation.
    • 

  • BLE depth: The nRF54H20 supports BLE 5.4 with LE Audio (LC3 codec), Auracast, Isochronous Channels, and enhanced Advertising">direction finding features. The EFR32MG24 at BLE 5.3 does not include LE Audio Isochronous Channel support.
    • 

  • Power efficiency: Both chips achieve competitive power figures. The nRF54H20's multi-core architecture with fine-grained power domain control delivers excellent BLE power efficiency for wearable use cases. The EFR32MG24's Thread sleep scheduling optimizes for battery-powered smart home endpoint duty cycles.
    • 

  • Price: The EFR32MG24 commands a premium for its multi-protocol and AI capabilities. The nRF54H20 is similarly premium for its BLE 5.4 depth and multi-core architecture.
    • 





Use Cases


nRF54H20 is the right choice for:
- Premium BLE products requiring full BLE 5.4 — LE Audio earbuds, hearing aids, Auracast broadcast infrastructure
- Medical and industrial BLE devices where BLE protocol quality and processing headroom dominate requirements
- Applications requiring advanced multi-core architecture for complex concurrent BLE and application processing
- Products without a need for Thread, Zigbee, or Matter over Thread mesh networking


EFR32MG24 is the right choice for:
- Matter smart home devices operating on Thread networks — door locks, sensors, light switches, thermostats
- Edge AI applications requiring on-device ML inference for occupancy, gesture, or predictive control
- Devices bridging BLE, Zigbee, and Thread ecosystems in multi-protocol coordinator or router nodes
- Large firmware applications benefiting from 1536 KB Flash accommodating multiple protocol stacks and OTA images simultaneously




Verdict


The EFR32MG24 is one of the most capable smart home SoCs available for Matter deployments — its combination of multi-protocol support, dedicated AI/ML acceleration, large Flash, and Secure Vault makes it a compelling platform for Thread-connected Matter devices with local intelligence. If your product targets the smart home space and benefits from Thread mesh networking, edge AI, and all Matter transports in one chip, the MG24 is difficult to beat. The nRF54H20 is the stronger choice when BLE 5.4 is the primary protocol requirement — its LE Audio support, multi-core architecture, and advanced BLE feature depth meaningfully exceed the MG24 in pure BLE capability. Choose based on whether multi-protocol Matter or premium BLE is your product's core wireless requirement.
