A look inside Apple’s new iPhone 5S and 5C

Apple's newest smartphone models hit stores today in many countries across the world, including Australia and China. For the first time, Apple is selling a second smartphone dubbed the 5C featuring a plastic back and bright colors. The pricier 5S now comes in three new colors - gray, silver and gold.

Technology firm iFixit disassembled a gold-coloured iPhone 5S and examined its parts and then took apart a 5C model.

Following are some of the key parts for the 5S model:

- Chips from Avago Technologies and Skyworks Solutions are featured in the iPhone 5S.

- Companies supplying parts for the new phone also include South Korean memory chipmaker SK Hynix and radio-frequency chipmaker TriQuint Semiconductor.

- Broadcom Corp’s BCM5976 chip is used for the touchscreen controller.

- Murata Manufacturing’s 339S0205 (based on the Broadcom BCM4334) Wi-Fi module.

- Includes chips from Qualcomm (PM8018 RF power management IC) and Texas Instruments.

Following are some key points of the 5C model:

- The hardware design on the 5C appears more similar to the 5S than to the iPhone 5

- The 5C uses a Toshiba Corp 16 gigabyte flash memory chip
