The M5Stack AI Pyramid Computing Box is a small computer with an Axera AX88500 processor that combines four Arm Cortex-A55 CPU cores with an NPU that delivers up to 24 TOPS of hardware-accelerated INT8 AI performance. But what really caught my eye was the physical design. There's a reason M5Stack calls this a "pyramid." While most mini PCs have a boxy design, this model is shaped like a pyramid with a case that's widest at the bottom but gets narrower toward the top.
