OneXplayer crowdfunding project offers an external GPU and SSD combo but also questions over performance
The manufacturer of the OneXFly has announced a new crowdfunding project to produce a new add-on for its handheld gaming PC. It's going to be an external GPU but one with an extra feature: one M.2 slot for a SSD.
External graphics cards (eGPUs) for handhelds aren't a completely new thing, as the Asus ROG Ally supports the company's latest ROG XG Mobile. That houses a 150W GeForce RTX 4090 Laptop chip and also acts as an I/O expansion unit, with four USB Gen 3.2 ports, an SD card slot, and an ethernet socket.
One-Netbook, the maker of the original OneXPlayer, is aiming to do the same for its OneXFly handheld. At the moment, the group is crowdfunding the project but if it's successful, then the OneXGPU will serve a similar function as the XG Mobile, though with a few significant differences.
Firstly, the GPU inside will be a Radeon RX 7600M XT, which is exactly the same as the desktop Radeon RX 7600 graphics card but with a lower power limit (120W vs 165W), so it shouldn't be too dissimilar, in terms of performance. That's assuming the OneXGPU doesn't reduce the power cap further, of course.
The project isn't replete with technical details, unfortunately, so it's not entirely clear how the unit will connect to other devices. The project's page states that the OneXGPU will be equipped with two HDMI and two DisplayPort outputs, two USB Type-A and one USB Type-C ports, plus a LAN and OCuLink connection.
Given that the OneXFly has two USB4 Type-C ports and this device is used in the promotional images for the eGPU unit, I strongly suspect that the one on the OneXGPU will be the same version. OCuLink is a type of PCI Express connection system, though it doesn't supply any power, unlike the PCIe slots in your desktop PC. That
