Ok, sounds like the Pi’s VideoCore VI is a lot less performant than I thought. I’d imagined it’d be closer to other mobile GPUs.

- my123 5y agoIt was probably a sane technical choice for them. RPi4 is made on the same node as the Snapdragon 800 (28nm), but with a much more recent (and bigger) CPU complex, using the Cortex-A72. As a bunch of RPis are headless anyway...
