OneXPlayer Launches OneXGPU 3 eGPU with AMD RDNA 4 Power

Key Takeaways

1. OneXPlayer launched the OneXGPU 3, featuring a desktop Radeon RX 9070 XT GPU with AMD’s RDNA 4 architecture.
2. The eGPU offers strong gaming performance, supporting 1440p and 4K gaming with 16 GB of GDDR6 VRAM.
3. Connectivity options include OCuLink and USB4, with OCuLink providing higher bandwidth but potential performance dips.
4. The OneXGPU 3 supports FSR 4 for enhanced 4K gaming and includes an M.2 slot for expanding storage with a PCIe 2.0 SSD.
5. Specific ports and pricing details are not yet available, but the eGPU is expected to be released soon following its CES 2026 announcement.

OneXPlayer has unveiled a new external GPU, the OneXGPU 3, at CES 2026. Unlike previous models that used mobile graphics cards, this version is equipped with a robust desktop GPU. It features the Radeon RX 9070 XT, which utilizes AMD’s RDNA 4 architecture, and is touted to deliver performance of up to 180 W.

Impressive Gaming Performance

This desktop GPU, boasting 16 GB of GDDR6 VRAM, is recognized for its excellent capabilities in 1440p and 4K gaming. Nevertheless, the connectivity method that the eGPU uses to link to the host could be a limiting factor.

Connectivity Options

As OneXPlayer pointed out, the eGPU connects to a host device via its OCuLink or USB4 port. The OCuLink can provide up to 64 Gbps of bandwidth, making it a superior choice compared to USB4. However, users might experience a performance dip of up to 25%, depending on the type of workload. That said, since both options are available, the external GPU is likely to work well with many mini PCs and handheld systems.

The inclusion of an RDNA 4 GPU allows users to utilize FSR 4, which will be beneficial for 4K gaming experiences. Additionally, the OneXGPU 3 features an M.2 slot that supports a PCIe 2.0 SSD, enabling users to expand the storage of their host devices (Gen 5 Crucial T710 currently priced at $169.99 on Amazon).

Ports and Availability

The company has assured that a good range of ports will be offered, though specifics on them have yet to be detailed. There is currently no information regarding the release date for the eGPU, and OneXPlayer has yet to disclose the pricing for the OneXGPU 3. However, since it was presented at CES 2026, we can expect the AMD external GPU to hit the market soon.
