The N64's processor had triple the clock speed of the Playstation's on top of having more RAM (up to 8MB versus the 3MB of the Playstation). Its graphics subsystem could also do perspective-correct texture mapping and push more polygons per second. It also had a hardware FPU which the Playstation notably lacked. It's pretty widely acknowledged that the N64's Achilles heel was its small texture cache which caused developers to use lower-resolution textures with heavy anti-aliasing than they otherwise would. This results in the characteristic smeary look of N64 games versus the Playstation's wobbly, pixelated aesthetic. You probably thought the PS1 looked better because of the more detailed textures.
I've no doubt (as a thoroughly amateur video game historian) that with a few small tweaks Nintendo would have ate Sony's lunch that generation. In that alternate universe Sega would have had better developer support for the Saturn and done crazy stuff with their super-wacky architecture too but I digress...
