As expected, Apple has taken the wraps off of its latest flagship smartphone at its Cupertino media event. According to Arstechnica, the new iPhone 5S is an upgrade in the vein of the previous iPhone 3GS and iPhone 4S—it is outwardly similar to last year's iPhone 5, but it includes a few key upgrades to keep the design going for another year.The 5S still has a four-inch 1136×640 display and a Lightning connector, and it retains the iPhone 5's taller and slimmer profile relative to older models like the iPhone 4 and iPhone 4S. However, it includes a new 64-bit "desktop-class" system-on-a-chip (SoC) dubbed the A7 that boosts CPU and GPU performance over the A6 in the iPhone 5.The chip has twice the general-purpose and floating point registers of its predecessor and is up to twice as fast at performing CPU tasks. The phone supports OpenGL ES 3.0, and Apple claims that the graphics performance in the 5S is 56 times better than in the original iPhone released six years ago. For the iphone lovers, I think its fascinating.
