The iPhone 6 Plus comes with a new processor, known as the A8. This is a 20-nanometer 64-bit CPU with 2 billion transistors. Early benchmarking using the Geekbench application suggests that the processor is dual core, and has a frequency of 1.4 GHz. It's paired with 2GB RAM. The iPhone 6 Plus is consummately slick and zippy in use
Don't take this to mean that the iPhone 6 Plus will be appreciably slower than is the Galaxy Note 4. iOS is more tightly coded than is Android, and so typically iPhones feel every bit as zippy as Android handsets with nominally superior specs.
The Qualcomm Snapdragon 805 may be fast, but isn’t much of a step up from the Snapdragon 801 of the Galaxy S5, which in turn isn’t all that much better than the Snapdragon 800 of the LG G2, released almost a year ago.
The truth: Qualcomm’s Snapdragon 805 is a chipset clinging onto a system architecture that is already in the grave and having dirt shovelled over its barely-moving limbs.
