AI Pyramid

SKU:AI-003

Description

AI Pyramid is a pyramid-shaped high-performance AI PC purpose-built for local AI inference and edge intelligence deployments. Powered by the Axera AX8850 SoC, it integrates an octa-core Cortex-A55 processor and a 24 TOPS @ INT8 NPU to effortlessly handle complex workloads including visual recognition, multimodal interaction, and on-device large model inference. AI Pyramid comes with 4GB LPDDR4x high-bandwidth memory paired with a dedicated hardware video processing engine, supporting 8K H.264/H.265 encode/decode and 16-channel 1080p parallel decoding to meet demands for AI vision analytics, video processing, and multi-stream media applications. Equipped with dual HDMI 2.0 digital multimedia output ports, dual Gigabit Ethernet, USB 3.0, and USB Type-C interfaces, it delivers exceptional flexibility for display output, networking, and peripheral expansion. It serves as a desktop-grade AI computing platform and is ideal for field deployment in edge computing scenarios. Designed for AI PCs, edge intelligent terminals, and smart interactive devices, AI Pyramid provides reliable AI inference performance for localized AI systems such as AI vision gateways, intelligent security, and local smart photo albums (Immich).

Device Power Supply

Power Requirement

This device requires a PD adapter with a minimum output of DC 9V@3A (27W). The unit will not power on with a DC 5V supply.

Memory Allocation

Memory partitioning between the AI Pyramid system and hardware acceleration resources is defined below:

4GB variant (2GB + 2GB): 2GB allocated to system memory; 2GB reserved for hardware acceleration tasks including NPU compute and video encode/decode.

This partitioning scheme ensures stable system operation while reserving dedicated memory for AI inference and multimedia processing.

I2C Bus Notice

Avoid accessing the RTC chip during microphone recording, as this may cause unstable behavior on the SYS_I2C bus.

RTC Clock Notice

After external power loss, the onboard RTC clock module retains timekeeping for up to approximately 20 hours.
