The 80286's I grew up using were between 4 and 12 MHz, depending on which model I was on and whether "Turbo" was enabled.

50 MHz is mid to low end 486 territory clock rate, which if it handles instructions as well (a big if) puts it squarely in the area of a lot of games.

If it isn't pipelined, then it'll probably be more like a 286 or 386 performance-wise. IIRC, Quake only had a smooth framerate on my 486DX-33 with floating-point support.

Quake should only have worked well on a Pentium because it could execute float instructions in parallel with CPU instructions, or something. At least Quake was unplayable on my 486DX (don't remember MHz, 66 or below). Even Doom was too slow.
