MediaTek Genio 420 (MT8371LV)
Powering Mainstream Edge GenAI IoT Applications
Overview
The MediaTek Genio 420 is engineered for embedded applications that require reliable, low-power implementation of edge AI and GenAI applications. Built on an advanced 6nm process technology, the Genio 420 integrates an 8th generation MediaTek NPU with 6.1 TOPS of acceleration (7.2 TOPS Total System) for handling complex AI tasks like object detection, image classification, and speech recognition as well as on-device support for GenAI applications and leading LLMs (Large Language Models). This enables real-time, low-latency AI inference on the edge, reducing reliance on cloud-based processing.
The Genio 420 also includes an octa-core processor with 2x Arm Cortex-A78 cores and 6x Arm Cortex-A55, and an Arm Mali G57 MC2 GPU. It supports up to dual displays, or a single display up to Ultrawide 5K60 making it a strong fit for smart retail, smart home, transportation/smart cities, healthcare, entertainment, education, industrial and enterprise applications. Integrated Wi-Fi 6E and Bluetooth 5.3 support, as well as expansion options for Wi-Fi 7, 5G and RedCap connectivity provide a platform for rich connected applications.
The Genio 420 further expands the Genio 720/520 family offering pin-to-pin hardware and full software compatibility. Combined with support for the latest LPDDR4X & LPDDR5X memory interfaces, the Genio 420 provides a cost-effective point to the family.
