Maybe its just the chip, not the entire board.
The article states "this operation involved chips made to convert analog signals to digital". So not GPUs, or even CPUs, but specialized ADC (Analog-to-digital converter) chips.
I thought those were built into the chip wafers nowadays. They still have seperate on-board chips for ADC?
Depends on the chip. A purpose built SOC may have them built in, but there's always more generic applications for a standalone ADC
