How Fast Is The iPhone 5's Apple A6 Processor?
Been wondering how fast the smartphone standard-setting Apple A6 processor is? Already, we knew the A6 is two times faster than the A5, 22 percent smaller, and has twice the GPU power, and also that it also helps with noise reduction, faster camera capture and better low light performance. Now, AnandTech has more details regarding the processor that's powering the 4-Inch iPhone. According to the website:
Quick analysis of the A6 SoC photos from the iPhone 5 launch event tells us all we need to know about the memory interface, speed and bandwidth of the new platform. As always, the A6 features a PoP stack combining the SoC itself and its DRAM. The package-stacked DRAM helps save space, which comes at a premium inside a device as small as a smartphone. PoP stacks are quite common in all modern smartphones. [...] Through crafty navigation of Samsung's product guide, Brian Klug got us the details. The K3P tells us we're looking at a dual-channel LPDDR2 package with 32-bit channels. The E7E7 gives us the density of each of the two DRAM die (512MB per die, 1GB total). The final two characters in the part number give us the cycle time/data rate, which in this case is 1066MHz.AnandTech put all the information together in the below chart, which shows "iDevice memory bandwidth vs. generation."

Clearly, this will help with the under-the-hood performance optimizations and, of course, that taller, 4-Inch display. Currently, the iPhone 5 is available to preorder from the Apple Online Store.
