The 3DS has much of it's internals housed in a SoC (System on Chip) just like it's predecessors. This is done to reduce build costs, cut down on power consumption, as well as make the PCB layout less complex and make the system harder to tamper with. The SoC, branded as the Nintendo 1048 0H, contains the CPU, GPU, DSP and VRAM.

According to official documents, the CPU used is a dual-core ARM11 CPU, clocked at 268MHz. One core is dedicated to system software, while the other is used for application programming, each known as the syscore and appcore, respectively.
