Dear homebrew developers why the original Xbox was able to emulate N64 games flawlessly and a twice faster CPU on a Raspberry Pi 3B/3B+/4 (and far more RAM) still can’t?
In: Technology
It’s not just CPU & ram, it’s the graphics card and software infrastructure.
A video card is basically a second CPU, but specifically designed to do graphical calculations. They are especially important for doing full 3d graphics, which become amazingly slow without them. The Xbox has one while the rasberry pi doesn’t.
Software infrastructure referrers to all the code and resources required to do the stuff that you want the system to do. Historically, consoles provided almost no infrastructure to the developers. Their code almost directly access the hardware. Most rasberry pis are running a full linux distribution, both allowing it to more easily do more things, but consumes a relatively high amount of resources.
