The PS Vita is powered by a quad-core ARM Cortex-A9 processor, each of which has a 2GHz clock speed. Several high-end mobile devices, notably Apple's iPad 2 and Android smartphones using the Nvidia Tegra 2 system-on-a-chip, already use the Cortex-A9 chip. However, considering that each of those devices only has a dual-core Cortex-A9 processor, the PS Vita has four cores, making it a much more powerful device.
