A new Nvidia Shield TV model is on the way, according to one mention at the FCC. The product is called the "NVIDIA Corporation SHIELD Android TV Game Console P3430" and has a Tegra X1 T210 B01 processor. That is, in all likelihood, the same Tegra X1 revision found in the new Nintendo Switch Lite, as well as the updated Switch with a longer battery life.
The submission comes after proof of a new variant of Shield TV appeared on the Google Play Developer Console last month. Not much is known about what the new model will be, or when it will be released. But the likely die-shrunk Tegra chip should mean that it could be smaller, more energy efficient, or run at higher clock speeds – or possibly a combination of the three.
