The CDC 6600 was initially intended for the National Security Agency (NSA) for cryptographic work. The computer was capable of performing 3 million calculations per second, and it was 10 times faster than the Stretch computer. The CDC 6600 was also the first computer to use pipelining to improve performance. The CDC 6600 was a 60-bit word length computer and had a memory capacity of 64 kilobytes.
