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
Spin Through Toolbar View Options
Although many people never change their toolbars from the default settings, all standard toolbars on the Mac offer six states: icon only, text only, and icon and text, with all three coming in normal and small size. You can change them by choosing View > Customize Toolbar.
But there's a shortcut that makes it easier to check out each variant. Simply Command-click the toolbar lozenge at the upper right of a window, and the toolbar switches to the next view. Click it enough times, and you cycle back to the start.
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.
