NVIDIA opted out of PlayStation 4, cites Sony not offering enough money@ 2013/03/15
In so many words, Tamasi says NVIDIA weighed its options against other potential products the company would be working on -- rather than producing discreet tech for a single console manufacturer, thus being unable to use said tech elsewhere -- and decided against it. "We had to look at console business as an opportunity cost. If we say, did a console, what other piece of our business would we put on hold to chase after that?" he tells the game site.
NVIDIA is indeed working on a variety of new products, including an Android-powered Tegra 4 gaming handheld called Project Shield. That's in addition to its bread-and-butter business of PC GPU development -- the company recently unveiled its Titan GPU, a $1,000 card with enough power to keep your gaming graphics needs met for years to come (or at least we sure hope so at that price).
