Apple's new iPad uses chips made by Qualcomm, Broadcom, Samsung Electronics and other semiconductor makers, according to repair firm iFixit, which cracked open one of the devices.
The newest iPad went on sale in Australia early on Friday, greeted by a throng of fans hoping to get hold of the 4G-ready tablet computer, which won good reviews but was not considered a major innovation.
According to iFixit, the iPad includes a Qualcomm LTE cellphone chip as well as a semiconductor from Broadcom handling wireless tasks like WiFi and Bluetooth.
The iPad's A5X application processor is manufactured by Samsung, as in past Apple devices.
Memory chips are supplied by Toshiba and Elpida.
Supplying parts for Apple's iPhones and iPads, the industry's gold standards, is considered a coup for chipmakers and other manufacturers.
A source familiar with the device's components told Reuters this week that Samsung and LG Electronics will both supply their liquid crystal displays for the iPad.
Apple doesn't disclose which company makes the components that go into its smartphones, and suppliers typically keep quiet for fear of angering the company.
One of the more widely followed teardown firms, iFixit is hired by a variety of clients who use its data for competitive intelligence, in patent disputes or to keep current on industry benchmarks.
