Intels largest chip manufacturing customer, Altera, has said that itll soon be building chips there based on — wait for it — ARM technology. Its Stratix 10 SoC will contain a quad-core, 64-bit ARM Cortex-A53 CPU, which Intel confirmed would be the first of that type manufactured by anyone. By contrast, Apples latest Samsung-built 64-bit A7 ARM chips used in the iPhone 5s are only dual-core.
