PS Vita Quad-Core Processor Developed by IBM, Sony and Toshiba

It seems like the trio that was behind the CELL processor found inside Sony’s PlayStation 3 was reunited to develop the quad-core CPU used by the Japanese company for the PS Vita portable console.

Previously believed to be fabricated by Samsung, the chip, which is marked as CXD5315GG, was revealed by a Tech Insights teardown to be manufactured as a joint effort between Sony, IBM and Toshiba.

As it was the case previously, IBM is in charge of the production process with the other companies being limited to developing the CPU.

Other info is not available at this point in time, but the end result is a CPU comprised out of four ARM Cortex-A9 cores that are installed in the same package with 512MB of DDR2-S4 SDRAM memory.

The rest of the chips found inside the PS Vita portable console come from a series of other companies including Qualcomm, Avago, STMicroelectronics and Marvell, to name just a few.
