This function returns the number of CPU cores available.

DECLSPEC int SDLCALL SDL_GetSystemRAM ( void )

This function returns the amount of RAM configured in the system, in MB.

DECLSPEC SDL_bool SDLCALL SDL_Has3DNow ( void )

This function returns true if the CPU has 3DNow! features.

DECLSPEC SDL_bool SDLCALL SDL_HasAltiVec ( void )

This function returns true if the CPU has AltiVec features.

DECLSPEC SDL_bool SDLCALL SDL_HasAVX ( void )
