Second, the statements "The ENIAC was something like 1Khz" and The Eniac could add 100,000 10-digit numbers in one second" seem unlikely to me to both be true. Did the Eniac really have a sufficiently parallel architecture that it could add 100 10-digit numbers in a single clock cycle?
According to http://en.wikipedia.org/wiki/ENIAC it seems to have clocked at 5 kHz (five times faster than Simon told us) and it also seems to have had 20 parallel accumulators, so for adding in parallel it could potentially have done up to 100,000 10-digits (base 10!) additions in a second. --Joshua Zucker
