Especially considering Switches can already be used to emulate games and are still currently found on store shelves. That strikes me as redundant, and therefore imo cost inefficient when you might as well just buy the switch if thats what you want.
As would I, I very much prefer the GBA style and size, especially when I splashed out for the BoxyPixel aluminum case
As for the Pi 4 data, I am officially home after a massively "Double U - Tee - Eff" couple months, I managed to drag through and I'm slowly scraping some free time from the bottom of the turd barrel that has been my recent life.
I realized reading my first post on this subject I mispoke; I said "CPU" when I meant "GPU". The CPU's in the Pi CM4 are... well, if you're counting every mA, they're mot trivial, but full whack, they pull about 250mA for a total. That's all 4 at 100%.
Not inconsequential, and dialing them back to 1000Mhz and fiddling with the goofy defaults of the clock governor does yield some good power savings, about 75ma(ish) but compared to the GPU and it's subcores, it's not basically a drop in the bucket. Even a smaller drop so if you're referring to the full RPi 4 and that PIG of a USB 3 controller.
Aside from USB in general being hungry, I was surprised to discover the VideoCore VI is an absolute power pig by default. Clocking that down (especially because in a "mobile" mode since we're running a lower res screen, just make sure the GPU PLL is fast enough to at least handle the pixel clock) and disabling whatever we can internally, like hevc, the yielded average power draw dropping from about 1.5amps to around 700ma; less than half.
I haven't had time yet to do any solid benchmarks, but the new VideoCore VI is... meh, I'd guesstimate 30%ish faster than the IV and even halving the clock it still "feels" pretty cracky even though...
I dunno yet, I have not much conclusive and I'll pull the settings and other notes and pop them up here when I get a bit more time and sort things out around the house, already spent too much time slacking on this post lol!
