- A modder built an 8,192-core GPU from RISC-V microcontrollers, each with an RGB LED, creating a combined graphics card and monitor.
- The project uses 8,192 chips (planned for 64,000 for 320x200 resolution), draws over 2,000 watts of power, and requires a custom 3D-printed tool for programming.
- Each microcontroller costs $0.13, leading to over $8,000 for the full array, with power supplied via a Corsair WS3000 PSU and custom converters.
- The design features custom six-layer PCBs in a circular arrangement, inspired by the Cray-1, and addresses challenges like cooling and high-current power delivery.
