“Is Apple’s A7 chip twice as fast at processing and graphics, as Apple promised when announcing the new iPhone 5S?” Stephen Shankland reports for CNET. “At least for Ben Weiss, the answer is yes — but his app is unusually well suited to take advantage of the new processor’s features.”
“The app in question is Iter9’s new Frax app for generating lavishly detailed fractal imagery by running mathematics calculations on both the CPU and GPU,” Shankland reports. “It gets a major speed boost on the iPhone 5S, Weiss said, evident in faster rendering times for the swirling psychedelic images laboriously calculated one pixel at a time.”
Shankland reports, “Frax is currently a 32-bit app, Weiss said, and it runs 50 percent faster on the A7-powered iPhone 5S compared with the A6-powered iPhone 5. And then came the second speed boost: When he compiled the first 64-bit version, Frax ran 25 percent faster than the 32-bit version on the iPhone 5S. Together, that means the 64-bit app runs nearly 90 percent faster on an iPhone 5S than the 32-bit version on the iPhone 5.”

MacDailyNews Take: A 90 percent performance boost. That’s quite the “marketing gimmick.”
