In the thread on RPi5's release announcement, I wrote that gpu performance is lagging compared to cpu, ram & storage upgrades on successive RPi models (VC6 being a minor upgrade).
Looks like that view may need revisiting... :-)
As an aside, I'd be curious how this VideoCore VII compares to gpus found on RISC-V boards like those based on JH7110 and TH1520.
From what I've read, those gpus (PowerVR based, iirc) are newish designs with a nice RAM bandwidth preserving architecture. BUT! Implementation (like, process node) matters, and so does driver support. Looks like RPi5 sure has the edge on the driver side!
Although (at this time) you probably wouldn't go for a RISC-V board for performance reasons anyway. But it would be nice to see how their gpus compare to the RPi5's in real-world benchmarks.
