I expected the OXP 4800U to be good but so far its very much exceeded my expectations.
I've got a SteamDeck on reserve but its an age away and I wanted something to PC game on the go now. After much research I'd Settled on and Aya Neo because the AMD APUs appeared better than the Intel ones. And then I noticed something, the OXP comes with a micro SD, Not sure how I missed that on my research. So that swung it.. The 5700U models were out of my price range but the 4800U was perfect. There are tools that let you tweak the TDP and the clock speeds so you can tailor the performance, but so far I've not needed to.
The OXP is pretty massive, but for lap gaming its perfect. Not sure you'd play it holding above your head in bed.
The display is brilliant, the APU will struggle to display the screen at native resolution for the most modern AAA titles but if you don't mind tweaking games you'll get a very playable experience. I've found aiming for SteamDeck type settings gets the most out of the OXP. So I aim for 720p or 800p, low to medium settings and run in power saving mode, so the CPU rarely pulls more than 15W which means very good battery life and @30+ fps in AAA games and massive frames in indies, so worth locking them to 60fps which will reduce the power even more.
Install a mix of big budget games and indie and use the conservative settings and you'll have hours of gameplay in the palm of your hands.
Not only can you run your Steam library but you can use your Origin, Epic, Amazon games and GoG all on one device. Currently I'm running my Epic games on a 512gb SD and also some rpcs3 emulation.
My biggest bit of advice is pay the extra for the carry case, its a tight fit but it protects the OXP perfectly.
Worst thing about the console isn't the console itself, its the 65W charger. 1. the supplied USB is too short, could do with a decent 3mtr one (which I bought, make sure its a PD capable one). 2. the charger itself is very small (presumable its one of these never gallium nitride GaN ones) but it doesn't get very hot and it charges brilliantly fast. But the biggest issue I have is the UK adaptor, which is a pretty lose fit so you find the charger starts to come away from the adaptor after a short time in the wall although its never stopped charging. I'd suggest getting a spot of glue to hold it tightly in place.
The OXP came supplied with Windows 11, which I planned on upgrading too so this saved me some time. Its still a little unstable in that i've had a couple of apps stop working and the only fix was uninstall and reinstall. One of these apps being FxSound audio enhancer, which I suggest you try as it really improves the quality of the sound from the OXP.
I aim to create a channel mostly dedicated to showing the resolution I use for best balance of fidelity/fps and battery life so keep your eyes peeled.
