Description
This is a fun one—it's definitely not the kind of GPU where people would ask "will it run Crysis", especially since a headline feature is 2D graphics acceleration (not even 3D yet!).
But the ASRock Rack M2_VGA is an M.2 form factor graphics card that sports a lone VGA port and 16MB (yeah, MB, not GB) of DDR graphics memory.
I doubt it will even be as fast as the built-in graphics on the Pi, but it would be interesting to see if it works. It uses the SiliconMotion SM750 graphics chip, which actually supports up to two DVI/HDMI/VGA displays, as well as two video inputs which can be overlaid on those outputs.
The chip is mostly known for being helpful in embedded or server graphics situations, and is not a 'powerhouse' by any means. Just a little utilitarian chip that sips less than 2W of power maximum (making it suitable for lower-power scenarios where you still need a display or two, but don't do gaming or ML/AI applications on it).
It seems like there's a mainline driver since a few years ago (SM750), and it would be interesting to see if it 'just works' (compared to the other cards). It seems like the chip itself uses BIOS (and was designed in 2012), so that gives me a little pause.
But the chip is simple enough and documented enough that I wonder if we could bring it up manually if the driver starts barfing on memory allocations like all the other GPUs I've tested have (AMD and Nvidia).
