The A7 is Apple's first 64-bit mobile SoC. Eventually teardown experts aim to explore the guts of the chip to determine details, such as how many cores it uses.
"We have confirmed through early analysis that the device is fabricated at Samsung’s foundry," Chipworks reports.
A look inside the A7 (APL0698) found a contacted gate pitch of 114 nm (above). That suggests it is made in the Samsung 28nm HKMG process, the same used for the Exynos 5410, application processor used in the Galaxy S IV, Chipworks said.
Chipworks provided external die and packaging photos of the A7, including pictures of the top metal die and package markings (below). A full de-capping of the chip is still in process.
