Digital foundry did a wierd analysis on this. They dint have the unit but analised the video of ign and valve.
I guess their opinion could change when they get the actual unit and test it themselves. But as of now they claim its a 720p console. They say the memory bandwidth is half that of the ps4 wich shows the results. And that that 1.6 ghz of the GPU might not be realistic or constant with that 15 wats tdp. So this at least on handheld mode is weaker than an x1.
Have to see it docked.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
