Based on addition and subtraction, 625000x slower or so than a 2.5ghz cpu

I wish the project said how many CPUs could be run simultaneously on one GPU.

It might be worth having a CPU that's 100 times slower (25 MHz) if 1000 of them could be run simultaneously to potentially reach a 10 times speedup for embarrassingly parallel computation. But starting from a hole that's 625000x slower seems unlikely to lead to practical applications. Still a cool project though!

So it could run Doom?

Doom it's easy. Better the ZMachine with an interpreter based on DFrotz, or another port. Then a game can even run under a Game Boy.

For a similar case, check Eforth+Subleq. If this guy can emulate subleq CPU under a GPU (something like 5 lines under C for the implementation, the rest it's C headers and the file opening function), it can run Eforth and maybe Sokoban.
