Octacore

I'm not sure I would expect great performance on 8 cores. The PSP is single threaded, so there are limits to how we can spread it out - PSP games aren't designed to take advantage of multiple cores. Someone would have to port the the games you're interested in to Android - maybe you should send that desire to the original developers of the game.

Vulkan may work on your device, and it may eventually be faster than it is now, but an 8x or even 4x speedup is pretty unlikely. Vulkan can reduce overhead, but it's not really going to make actual drawing go faster.
