One Netbook has been cranking out handheld gaming PCs under the ONEXPLAYER brand for a few years. But like most computers in this space, they’ve tended to rely on integrated graphics rather than more powerful discrete GPUs.

Now the company is preparing to launch a solution that (sort of) offers the best of both worlds: an external GPU dock that connects to any handheld (or laptop or desktop computer) via Oculink or USB4 ports. It’s called the ONEXGPU and the first version will basically be a portable, external 120W AMD Radeon RX 7600M XT GPU. One Netbook plans to launch a crowdfunding campaign for the graphics on November 28 with early bird pricing starting at $599. A preview page is now live.

If that all sounds familiar, that may be because rival handheld maker GPD already has a small graphics dock with the same GPU. It’s called the GPD G1, and it’s already available from AliExpress for $695.

Like the ONEXGPU, the GPD G1 has both a USB4 port for 40 Gbps connections and a 63 Gbps Oculink port for even higher-speed connections. And while there aren’t a lot of devices on the market that actually support Oculink yet, GPD has two of them, including the GPD Win 4 2023 and GPD Win Mini.

But there are a growing number of other devices that also have Oculink ports, including mini PCs like the MINISFORUM EliteMini UM780 XTX, handhelds and mini PCs from AYA Neo. Interestingly, I don’t think One Netbook has offered a handheld or mini laptop with an Oculink port yet, but including one in the graphics dock could be an indication that next-gen models might have that feature.

Like the GPD G1 graphics dock, the ONEXGPU should have the same 120W Radeon RX 7600M XTGPU with 32 RDNA 3 compute units, 32MB of cache, and 8 GB of GDDR6 memory.

It’s hardly the fastest GPU available, but it should be speedy enough to bring a big boost in graphics and gaming performance to handhelds, among other things.

One Netbook hasn’t announced pricing, availability, or detailed specs yet, but the crowdfunding preview page spells out some details. For example, we know that the dock will include RGB lighting, a fan for active cooling, and a set of ports that includes:

  • 1 x Oculink
  • 1 x USB Type-C
  • 2 x HDMI
  • 2 x DisplayPort
  • 2 x USB 3.2 Type-A
  • 1 x Gigabit Ethernet

There’s also an M.2 2280 slot inside the case, allowing users to add an a PCIe 2.0 SSD that will serve as an external storage device when your computer is connected to the ONEXGPU dock.

Since the graphics card is rather power hungry, the dock isn’t meant to be run on battery power, and is instead designed for use while plugged in. But its relatively small size (it measures 188 x 106 x 16mm and weighs 768 grams) means the ONEXGPU could be easier to throw in your bag and take with you than some most graphics docks.

  1. “But unlike the One Netbook model, the GPD G1 also has a 63 Gbps Oculink port”
    I’m not sure I understand, it looks like they both have Oculink ports.

    1. This is what happens when I update an old post instead of writing a new one. I forgot to change that detail when new information came to light. I’ll do that now, thanks!

  2. Brad, THANK YOU for the article in which you highlight USB 4 <3
    I’ve been writing about the benefits of the quick implementation of USB 4 for a long time (many people didn’t share my optimism and demand for the quick implementation of the new standard)..
    They announced the use of 40 Gbps, but I believe they will also introduce 80 Gbps soon. I’m sad that the device doesn’t have PowerDelivery (if it supports it, please correct me). I am delighted with this device because it has an Ethernet port!! The only thing I’m missing is an m.2 nvme slot that the operating system would recognize as a disk, not a pendrive (flash disk support is possible). I know I’m a dreamer, but it’s already close to perfect. The only thing I’m missing is information whether the device supports DisplayPort 2.1 and Alt-Mode.
