New handsets expand to 512 GB and $1,099

Rick Merritt, EETimes, SAN JOSE, Calif., Sept. 12, 2018 – Apple announced a family of three iPhones powered by a 7nm SoC enabling up to 512 GBytes of memory. The handsets range in price from $749 to $1,099, increase battery life by 30 to 90 minutes, and ship within two to six weeks.

The smartphones, and two new models of the Apple Watch, generally packed larger screens and upgraded chips in slightly smaller devices. None of the devices support 5G cellular networks, expected to start switching on later this year, but the handsets support Gbit/s data rates, an LTE capability that Qualcomm was early to support.

Apple's 7nm A12 Bionic chip packs 6.9 billion transistors and is "the most powerful chip in a smartphone," said chief executive Tim Cook.

The A12's two high-performance CPU cores deliver 15% more speed and 40% greater efficiency than the prior A11. Four other cores are 50% more efficient than those on the prior chip. The 10-nm A11 was touted as sporting up to 25% more performance and 70% more efficiency than its predecessor, reinforcing reports that the 7-nm node delivers declining advantages.
