Tbh dude, lots of people beat you to making a handheld steamdeck like pc, its not exactly a new concept.
Likely because even the original OneXPlayer at 8.4" is ... rather huge. For a handheld, that is. Unless you want some sort of "half controllers glued to the sides of a tablet" look (which would also make for a pretty terrible carrying experience in any bag, with the protruding handles, almost necessitating the handles being removable), 11" is just far too large to hold like this in a comfortable way. A 11" device would also likely weigh quite a lot more just from the bigger screen. The Switch is 400g, the Steam Deck is 670g, and the OneXPlayer is 825g. An 11" device would likely tip 1kg - that's starting to get really heavy for this type of usage. There's a rather fine balance between screen size and controller size for these things, and judging by the OneXPlayer, 8.4" is on the bigger side of what is feasible.
Sold. I the two links, especially the photo with the tablet controllers, have convinced me.
That's not even remotely doable in a handheld form factor - or in a portable form factor at all. Remember, most gaming laptops severely limit their power draws when running off battery, and still last for an hour or less. For any reasonable battery life while gaming you need APU-level power draws - 15-35W at most.
Honestly it is hard to justify making something able to play Witcher 3, while being ultra-portable but only lasting 47 minutes. At <1h one has to wonder, why making it so portable in the first place, or why does it have to play Witcher 3 ...
They're just trying to do a tad too much at once. I mean, it does decently with lightweight tasks - 6h H.264 video or 5.5h web browsing isn't bad - just mediocre. It clearly does a passable job at tamping down power draw when not under heavy loads. But for gaming it is clearly meant to be a tethered experience - you just get to choose if you game at home with the XG mobile dock or somewhere else with the built-in GPU. You could probably extend its battery a bit with a decent USB-C PD powerbank, but even something very much made-for-purpose like the Steam Deck - or even the Switch! - only lasts for a handful of hours. And even the lowest power dGPU will double power draws from a well tuned APU. The Flow X13 is likely better for on-the-go gaming, especially the upcoming/newly launched versions with 6000-series APUs, as they should deliver good gaming performance even on the iGPU, and the battery is slightly larger too. But of course those aren't handhelds either (even if they do transform into a "tablet" mode). Putting SteamOS on one of these would be interesting though ...
That is an even better idea, then it's just a dumb screen and controllers and not much else. Battery life would be much better and you could make it much lighter too.
That's a pretty good idea. The main challenge with things like that is that many of them require line-of-sight to work (WiGig, for example), and are severely hampered by tings like your body getting in the way of the signal. But still, making a battery powered handheld wireless HDMI display + controller combo would overall be relatively trivial - and you could probably get really good battery life too, as long as the display and receiver don't gobble up too much power.
That's pretty cool, though having used similar solutions on PC before I'm worried about input lag (and, on a larger screen, compression artifacting from the input). Still works in a pinch though!
Steam Remote Play lets you do the same thing too. Lag can still be an issue though, especially over WiFi, but it's highly dependent on the game and your network conditions. I've used it with some decent success over wired home networks though, even for relatively latency sensitive games. And I agree, I trust native encoding/decoding like this far more than external dongles when it comes to latency - as long as the hardware is up for it, that is. But it's much more of an "either it works or it doesn't" situation rather than the iffy in-between laggy/artefacting of low quality capture devices. For example, I've used my laptop as an external display for my travel gaming PC with both an Elgato HD60S and a Genki Shadowcast, and both work very well if it's connected to power - but if it isn't, things get really laggy. I would assume the video signal from those devices is decoded using QuickSync (and CPU loads are low during use, so that seems correct), but things still get unusably laggy unless the laptop is on its charger.
Yep something like that. I haven't really tried with Steam, just the Xbox, and while it isn't perfect like playing natively, with casual games it's not a problem. Meanwhile my brief uses of xCloud has been pretty terrible and I have decent wireless setup too.
