Which PlayStation handheld used a quad-core ARM Cortex-A9 MPCore CPU?

The PlayStation Vita used a quad-core ARM Cortex-A9 MPCore CPU.

Sony designed the Vita as the successor to the PlayStation Portable and released it in Japan in December 2011, followed by wider markets in February 2012. Its system-on-chip combined a quad-core ARM Cortex-A9 MPCore central processor with a PowerVR SGX543MP4+ graphics processor. This architecture supported considerably more advanced portable visuals than the earlier PSP hardware.

The Vita also included a five-inch OLED display on its original model, dual analog sticks, front and rear touch surfaces, cameras, and motion sensors. Games were distributed on proprietary Vita cards, while downloadable software and some system data could use Sony’s proprietary memory cards.

The CPU name is sometimes shortened to “ARM Cortex-A9,” but the complete processor description identifies the quad-core MPCore implementation. It should not be confused with the PSP’s MIPS-based Allegrex processor or with the PlayStation TV, which was a Vita-based microconsole for television use rather than a separate handheld generation.
