PS Vita will reportedly be powered by a Samsung manufactured CPU.
That's according to Japanese trade paper Semiconductor Industry News (via Andriasang), which says the processor will be made using a 45 nanometer process.
Vita is expected to launch in at least one territory - most likely Japan - later this year, ahead of a western release in 2012. It'll be available for the public to sample at this September's Tokyo Games Show.
EA said this week that Vita - and Nintendo's portables - face a challenge to succeed in light of growing competition from the smartphone and tablet markets.
