When I first saw the ONEXPLAYER G1, I had one thought: finally. A handheld that doesn’t just flirt with high-end specs but dives headfirst into the desktop pool. With AMD’s latest Ryzen AI chip, a beastly GPU, and a 2.5K display crammed into a surprisingly portable chassis — this thing is part gaming console, part laptop, part fever dream.
But is it too much power in too small a body? Or the best Steam Deck killer we’ve seen yet? Let’s get into it.

Spec Talk: Why These Numbers Matter
The ONEXPLAYER G1 doesn’t mess around. The top-end HX 370 chip with the Radeon 890M delivers the best iGPU gaming performance on the planet right now. We’re talking Forza Horizon 5 at high settings, smooth 60+ fps — without needing an eGPU.
That said, if you’re the kind of person who wants an external GPU, this thing supports OCuLink — meaning you can hook up a full desktop GPU and barely lose performance. That’s a game-changer.
The 144Hz screen is sharp, color-rich, and ridiculously smooth for a handheld. Combined with fast LPDDR5X RAM and up to 4TB of SSD, it’s closer to a gaming laptop than a Switch or Steam Deck.
Design and Feel: Like a Spaceship in Your Hands
ONEXPLAYER keeps its design signature alive here — bold lines, huge display, premium materials.
• The matte-textured back feels secure in-hand, no sweaty slip-ups
• The orange-accented analog sticks are Hall-sensing — precise, drift-free
• Triggers are magnetic and clicky, very Xbox Elite vibes
• Detachable magnetic keyboard (sold separately) turns it into a mini-laptop
• The RGB light bar under the screen? Overkill and awesome
All the ports are either top-facing or bottom-aligned — surprisingly ergonomic. And yes, you can dock this thing and use it with a full-size monitor and keyboard. It’s that versatile.
Testing It Out: Real Games, Real Sweat
I tested the G1 with the Ryzen AI 9 HX 370 and 32GB of RAM. Here’s how it held up:
• Cyberpunk 2077 (Medium, FSR 2.1 Balanced) — 48–55 fps
• Baldur’s Gate 3 (Ultra, 1080p) — 60+ fps indoors, 42–50 outdoors
• Hi-Fi Rush (High, 1600p) — locked 60 fps
• Elden Ring (High, 1200p) — 55–60 fps with no major dips
And with an external GPU via OCuLink (used a desktop RTX 4070): pure desktop gaming, no joke. Alan Wake II ran like butter.
Battery life isn’t miraculous — expect 2.5 to 3.5 hours under load, 6+ in light use — but the 100W USB-C charging helps it bounce back quickly.
How It Stacks Up
• Steam Deck OLED: More affordable, better battery, and still solid — but can’t touch the G1’s power or screen sharpness.
• ROG Ally: Slightly lighter, with a strong 7840U chip — but limited to 1080p and no OCuLink support.
• AYANEO Kun: Bigger battery and screen, but heavier and more expensive — similar power, less portability.
Verdict: G1 is best for people who want power and future-proofing (OCuLink!), without sacrificing portability.
