PicoRio Linux RISC-V SBC is an open-source alternative to Raspberry Pi board

Original iPhone managed 60fps with an even slower processor (412MHz - https://everymac.com/systems/apple/iphone/specs/apple-iphone...). I know it only had 320x480 resolution, but if you consider that the CPU's job is to keep the GPU busy then I see no reason that efficient software could get a smooth UI out of this processor paired to a 60fps-capable GPU. Having said that, 'efficient software' is like hens teeth nowadays :)

Depends on your expectations, technically NES had 60 FPS GPU.

If you want to drive a FullHD at that rate, and render GUI comparable to modern phones - you need 3D acceleration, ideally programmable shaders, and the fillrate.

GPU is unavailable at launch, they say it will appear in later versions, and it will be a PoverVR. Never said which PowerVR.
