It looks like clock speeds of two models, both that use a factory overclock, have been leaked by Tum Apisak. > Recapping the specifications for those who missed out our previous article, the AMD Polaris 30 GPU will be based on the 12nm process node. It’s not known whether AMD will be relying on the Global Foundries 12nm process or the much advanced TSMC 12nm node which is being used to make the NVIDIA Turing GPUs. Considering that Polaris GPUs have been featuring a FinFET process design from Glofo, it won’t be a surprise if AMD ends up using them for 12nm too.
