Hobbyist Builds 8,192-Core GPU from $0.13 RISC-V Chips
Bitluni assembled a DIY GPU using 8,192 WCH CH570 microcontrollers, each costing $0.13, into a parallel array. The build required six-layer PCBs, individual crystals per chip to fix clock distribution, and a 3 kW power supply. It highlights engineering challenges like cross-talk and fan-out limits that scale from small projects to massive clusters.
Meridian48 take
The project is a clever hack but underscores that scaling simple cores into a functional GPU involves non-trivial hardware engineering far beyond the chip cost.
