“The iPhone 5 looks to be the fastest smartphone we’ve ever tested at PCMag.com,” Sascha Segan reports for PC Magazine.

“With its mysterious, Apple-designed A6 processor, the iPhone 5 is unique in the world of smartphones,” Segan reports. “Most high-end phones nowadays run on one of two architectures: ARM’s Cortex-A9, which is used by Nvidia, Texas Instruments and others, and Qualcomm’s Krait. But the A6, as AnandTech discovered, is something completely different — an ARM-compatible system-on-a-chip designed, top to bottom, by Apple.”

Segan reports, “Based on these benchmarks, the iPhone 5 lives up to the promise of being twice as fast as the iPhone 4S. It’s also, for now, the fastest handheld computer sold in the US.”
