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
View Extra Bluetooth Details in Snow Leopard
In Snow Leopard, Option-click the Bluetooth icon in the menu bar to view a few additional items in the Bluetooth menu. Specifically, it enables you to open three utility applications: Bluetooth Explorer, Bluetooth Diagnostic Utility, and PacketLogger. These are likely of interest primarily to experts, but if you're having troubles with Bluetooth, the Bluetooth Diagnostic Utility in particular may be useful. (These tools are available only if you've installed Apple's Developer Tools.)
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.
