*Speculation* Nintendo NX GPU is AMD Arctic Islands based?
Here is the info from wccftech and just how likely this could actually be based on a few things we know about Nintendo and how they have made consoles in the past:
This new family of 16nm GPUs is informally code named “Arctic Islands”. The new family will be based on AMD’s 3rd generation GCN (Graphics Core Next) architecture. Interestingly — despite the existence of three+ different iterations of GCN namely GCN 1.0 ( HD 7000 series ) , GCN 1.1 ( R9 290 series) , GCN 1.2 ( R9 285 and 380) and Fiji ( R9 Fury X, R9 Fury and R9 Nano) which is based on an updated GCN 1.2 design — according to AMD there have only been two generations of GCN so far. With the next major iteration coming next year in the form of the “Arctic Islands” family of graphics chips.
This graphics architecture will power everything from next generation mobile and desktop GPUs to APUs and semi-custom chips. There’s also strong evidence to suggest that Nindendo’s next generation gaming device “Nintendo NX” – which is coming next year – will be powered by an AMD semi-custom SOC. Making it a very likely candidate to feature AMD’s 3rd generation “Arctic Islands” GCN architecture.
The flagship GPU in the family has been numerously purported as “Greenland“. Which is set to be AMD’s most powerful and most advanced graphics chip to date. In addition to being built on an advanced FinFET manufacturing process – likely 16FF+ at TSMC, the same for Nvidia’s Pascal – the Arctic Islands family will feature second generation High Bandwidth Memory Technology and as mentioned earlier an updated 3rd generation GCN architecture. These -16nm, HBM2 and GCN3- are going to be the three main performance and power efficiency driving features. Greenland specifically is rumored to feature up to 18 billion transistors and 32GB of second generation HBM with 1TB/s of memory bandwidth. Making it the largest ever graphics engine conceived by the company, at approximately twice the transistor count of AMD’s current flagship code named “Fiji” powering the Fury series of Radeon graphics cards.
