TweakTown writes word on the street is that NVIDIA's 16nm GPUs may be delayed because TSMC is focusing on cranking out A9 chips for Apple and its new iPhones. TSMC had originally scheduled mass production of its 16nm FinFET process for Q1 2015 but it seems the company may not be able to deliver until June/July of 2015.
It takes some time for a chip to move from mass production to actual retail availability so this news may mean that NVIDIA won't be able to deliver 16nm GPUs until late 2015 or early 2016.
For NVIDIA, this means that the company won't be able to bring its "Big Daddy" GM200 chip to fruition, at least on 16nm, until late 2015 or early 2016. The process shift is a lengthy one, something we saw with "Big Kepler" a couple of years ago. 28nm went into mass production over at TSMC in October of 2011, but the GTX Titan was released in February 2013. Two years of waiting for NVIDIA, with TSMC finally getting its act together for 28nm volume production, in order to built a chip that was reasonably priced, which resulted in the GeForce GTX 780.
