"There's an additional wrinkle to the story too, albeit one we should treat with caution as it is single-source in nature with a lot of additional speculation on our part. This relates to the idea that the Tegra X1 in the NX development hardware is apparently actively cooled, with audible fan noise. With that in mind, we can't help but wonder whether X1 is the final hardware we'll see in the NX. Could it actually be a placeholder for Tegra X2? It's a new mobile processor Nvidia has in its arsenal and what's surprising about it is how little we actually know about it."
"We also know it has an unusual CPU set-up - two next-gen versions of Nvidia's own Denver CPU cores, paired with an ARM quad-core ARM Cortex-A57 CPU cluster. But what we don't know is the form its GPU component will take because unusually, Nvidia has released no specs on this element whatsoever. Assuming that X2 offers a generational leap over X1 and uses the same Pascal architecture found in its new GPU line, we are potentially looking at power more in line with the current-gen consoles. And if Pascal is in play, it will also use 16nm FinFET production technology compared to X1's 20nm process, meaning it is much more power-efficient. Nintendo could also downclock the chip for further efficiency savings and longer battery life while retaining the lion's share of its processing power."
