Tegra K1 and Windows

Nvidia just unveiled their Tegra K1 in the CES which sports Kepler graphics core. For those who don't know: Kepler is the codename of the architecture used in Nvidia's GTX 600 and 700 line.

My question is very simple. Do you guys think that it will give Windows RT, and in turn Windows Phone a big boost in gaming now that a full DX11.1 GPU is available?
