There’s no question that the A7 chip in the iPhone 5s is the fastest processor ever to grace an iPhone, but how does the performance it provides compare with that enjoyed by previous generations of the iPhone? In this fascinating YouTube video, user EverythingApplePro lines up eight iPhone models and shows how they compare at powering up and down, and loading several Web sites. follow link
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
Fascinating Speed Comparison across All iPhone Models
I shared this with a tech friend who made an interesting observation:
"He also (perhaps unwittingly) hits on a truth about modern hardware that is the chip making industry is really struggling now to find new ways to keep improving processing speed. We’re seeing a flattening of the progress curve as each generation slows down the speed of progress relative to the previous generation. Chipmakers can’t keep doubling speeds every 12-18 months like they did a decade ago."
Instead, companies have to put the CPU power to use in new and innovative ways, such as by tracking usage to predict behavior and make it better, for instance. That's something that wasn't possible in the past because the CPUs were busy handling just basic tasks.
