Calculating Pi digits on the first Intel microprocessor (Intel 4004)
One day I thought about the performance gap between the first Intel processor and modern machines. Of course, we can try to do some estimations empirically – we know clock rate and how the pipeline is organized and what features intel 4004 CPU has (but it would not be standard FLOPS, because there was no embedded support for float numbers yet). But there are few details: architecture bit width (on ... ⌘ Read more
