“The A9 uses a dual-core ARM CPU based on a custom 64-bit CPU architecture, continuing to refine the 64-bit design in the A7 and A8. Geekbench reports that the CPU runs at 1.84GHz, a significant increase from the 1.4GHz Apple A8 in the iPhone 6 family,” Andrew Cunningham writes for Ars Technica. “The A8 wasn’t all that much faster than the A7 — ‘up to 25 percent,’ though in our testing it was often less than that. In Geekbench the A9 is over 50 percent faster than the A8 in both single- and multi-core benchmarks. It’s fast enough that it can match the triple-core A8X in multi-core tests despite having one fewer CPU core, which bodes well for the iPad Pro’s A9X (we still don’t know how many cores that one’s going to use, but three or even four seems plausible).”
“The faster GPU fixes a problem we noticed in the iPhone 6 Plus in our review. It’s rendering a 2208×1242 image and then scaling it to the phone’s 1080p display. The same A8 GPU had to push 1,741,836 more pixels on the 6 Plus than in the 1334×750 display of the 6. As a result, you can catch the occasional stutter or dropped frame even as you navigated around the UI. It’s still visible in iOS 9—jump into the multitasking switcher and you’ll notice it every time,” Cunningham writes. “That’s all gone in the 6S Plus, which is totally fluid in all the places where the 6 Plus drops frames.”
“3D Touch in particular feels like it could subtly change the basic smartphone interaction model, at least once we get used to it,” Cunningham writes. “Tt speeds up basic, repetitive tasks well enough that we won’t be surprised if pressure-sensitive touchscreens suddenly become a mainstay feature in the flagship Android phones of 2016… The iPhone 6S is a good buy if you’re coming from a 5 or 5S, but keep your money if you’ve already got a 6 or 6 Plus.”
