Google's keynote at GDC today left us with more questions than answers in regards to Stadia, its upcoming game streaming service that is launching sometime this year. However, Google fed us just enough details about the hardware to whet our appetite, and perhaps provide a hint of how the service will perform in comparison to today's PCs and dedicated game consoles.

The goalpost has been set at 4K resolution gaming at 60 frames per second. Google also says Stadia will support HDR visuals. In the future, Stadia will scale to 120fps, and even 8K gaming, according to Google's bold claims.
