In brief: One-Netbook’s newly unveiled second-generation external GPU is the first known product featuring AMD’s Radeon RX 7800M mobile GPU. Internal benchmarks suggest that the chip could put high-end gaming performance within reach of connected handheld gaming PCs, low-end laptops, or mini PCs.Mobile Radeon RX 7800M debuts in external GPU unit, clears 60fps in Wukong

Laptop and mini PC vendor One-Netbook will soon open an Indiegogo campaign for the successor to the OneXGPU. The new external graphics card enclosure features AMD’s previously unrevealed Radeon RX 7800M.
For $760, the original OneXGPU provides low-end systems like handheld PCs, mini PCs, and laptops with respectable mid-range gaming performance through its RX 7600M XT. It also famously includes extra M.2 NVMe storage.
According to the specs for the OneXGPU 2, the RX 7800M nearly doubles the number of compute units from 32 to 60 and increases GDDR6 video memory from 8 GB to 12 GB. One-Netbook’s video shows the high-end mobile GPU running the Black Myth: Wukong benchmark comfortably above 60fps at 3,440 x 1,440 resolution using “high” graphics settings while connected to the company’s OneXPlayer X1 mini PC.
However, viewers might want to take the results with a pinch of salt until third-party reviewers gain access to the final product. In TechSpot’s analysis of the same benchmark tool, the desktop RX 7800 XT only managed an average of 57fps at 2,560 x 1,440 resolution on the high preset.

One-Netbook also claims that the 7800M can stay over 60fps in the 2018 God of War game at 2,560 x 1,600 and in Red Dead Redemption 2 at 1,920 x 1,200 with maximum graphics settings. The latter title’s top-end specs are infamously demanding.
Like its predecessor, the OneXGPU 2 supports plenty of connectivity options. It features USB 4.0, Oculink, HDMI 2.1, M.2, two DisplayPort 2.0 outputs, and more, enabling users to connect up to three screens. Launch and price details are forthcoming, but the company confirmed a 30-percent-off early-bird deal.
External GPUs have typically come in the form of bulky enclosures for used desktop parts, but companies like GPD and One-Netbook now offer travel-sized models based on laptop hardware. For example, a 7600M-based example from Hi GT Cube includes 100W charging functionality as a bonus.
Meanwhile, users can expect the 7800M to offer a good middle ground between the existing 7600M and the much more expensive RX 7900M when it eventually appears in high-end gaming laptops.
