The central processing unit powering Sony's upcoming portable PlayStation Vita console is being manufactured by Samsung, according to online reports out of Japan. A brief mention of this was made at the official website of Japanese industry paper The Semiconductor Industry News (as translated by Andriasang), though not much further context was provided. The unnamed chip is reported to be 45 nanometer -- 45 nm chips are known for their reduced electrical current leakage: processors in both the redesigned Xbox 360 S and PlayStation 3 Slim models are manufactured under this process in order to reduce power consumption. While 45 nm chips are no longer the state-of-the-art, they are still frequently used: both the iPhone and Nintendo's 3DS have 45 nm processors. Samsung also manufactures the ARM-based Apple A4 and A5 chips, which power Apple's iPad, iPhone and Apple TV products. The MIPS-based CPU on Sony's current portable console, the PSP, is manufatured by Sony itself.
