In the period the SNES was released, the CPU it had was SLOW. Compared to the Megadrive/Genesis system (7,61 MHz), the CPU was ultra-slow. Due to this CPU, the games were giving a slowdown faster. This slow CPU was assisted by a powerful Videochip.
This powerful grafical chip took a lot of strain off the slow CPU. It could do many wonderful things, like: Rotation, scaling, transparency and mode 7 (fake 3D).
The manufacturer of the sound chip is Sony. This chip was able to handle 44KHz of sound. In most games, only 22KHz or 11KHz was used. This was done to save memory. This chip put other consoles FAR behind itself.
The SNES had many great features, but due to the slow CPU, it was gone way to early. On the other side, the SNES had much software, and was sold very well.
