As most everyone knows, the both the iPhone 6 and iPhone 6 Plus pack a pretty decent punch when it comes down to how much RAM there is as well as the CPU and GPU. But for those that may not know, the very first iPhone sports just a 412 MHz CPU, 128MB of RAM, and a 320×480 pixel display. That being said, the iPhone has definitely made a lot of progress over the last seven years. Moving forward, a Youtube user by the name of EverythingApplePro was able to get their hands on every single version of the iPhone to do a side-by-side speed test. As one would guess each new iPhone generation gets a little quicker, however, it’s also interesting to see the design changes as well.
