I have a handheld with a 7840U (GPD Win Mini), and I love it. I do use it mostly for games, and I suppose if it were labeled a Z1 Extreme instead of a 7840U, I'd be just as happy with it. So I can somewhat see where you're coming from. But also I think it's becoming more common to want to run "real" (non-gaming) workloads that can leverage a GPU on devices without a discrete GPU, so I still think it makes sense as a general-purpose part. (Also, I think the Z1 was an Asus-exclusive part, at least initially, so if there wasn't a non-exclusive variant, then I'd be stuck with something inferior.) > ...and while they quote a 28W TDP, the actual max-power draw is stratospheric for a U series (well over 50 watts). The ideal TDP for that chip is around 18W, with diminishing returns after that. (I usually run mine at 7-13W depending on the game.) Beyond 25-30W, you get only marginal performance gains relative to the amount of additional power, so while it technically can use over 50 watts, it's clearly not designed for that and the extra performance isn't worth it when you're running on battery.
