If Nintendo does go with Arctic Islands NX can very well match or exceed PS4
AMD 14nm/16nm Arctic Islands GPUs Arriving In 2016
"Su confirmed that AMD is set to update its entire graphics portfolio in 2016. The new family of GPUs will feature significant architectural enhancements as well as cutting edge FinFET process technology to deliver twice the performance per watt of AMD’s current graphics offerings."
"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."
