Exploring the Power of Nvidia RTX 5090 in a Handheld Gaming Setup

Handheld gaming PCs are evolving rapidly, and the recent experiments with Nvidia's RTX 5090 graphics card have unveiled fascinating potential. Imagine connecting the world’s fastest graphics card to a handheld device, delivering desktop-level performance in a portable format. In this article, we'll explore the strengths and weaknesses of using an external GPU (eGPU) via the Oculink interface, focusing on the gaming experiences provided by the RTX 5090 paired with portable devices like the GPD Win Max 2.

Unleashing Desktop Performance on Handheld Devices

By combining a powerful $1,999 RTX 5090 Founders Edition with a Minisforum DEG1 external GPU dock and the GPD Win Max 2 handheld, we witnessed exceptional gaming performance. Despite only utilizing an AMD Ryzen 8840U CPU and limited PCIe 4.0 bandwidth, frame rates exceeded 100 fps in demanding titles like Cyberpunk 2077 at 4K ultra settings, demonstrating the potential of handhelds.

Benchmark Performance: RTX 5090 eGPU vs. Traditional Desktop

The benchmarks provide a compelling comparison between different setups:

• Assassin’s Creed Mirage: 109 fps with RTX 5090 eGPU, compared to 144 fps on a traditional desktop setup.
• Cyberpunk 2077: 109 fps on handheld vs 152 fps on desktop without ray tracing.
• Returnal: 131 fps on handheld vs 142 fps on desktop.

While the eGPU configuration delivered impressive results, it did showcase some limitations compared to top-tier desktop hardware, indicating there is room for improvement as technology progresses.

Challenges of Using Oculink: Pros and Cons

Oculink cables present intriguing advantages and notable drawbacks:

1. Bandwidth Limitations: Currently, Oculink doesn't offer the same convenience as Thunderbolt, notably lacking hot-swapping capabilities, which can be frustrating.
2. Hardware Fragility: Oculink connections can be less robust than counterparts, leading to issues with accidental disconnections.
3. Compatibility Issues: Limited device availability hampers mainstream adoption, and users may face driver problems with certain GPUs.

The Future of Gaming: Handheld Consoles with eGPU Capability

As handheld gaming continues to advance, the combination of portable consoles and powerful eGPUs suggests a compelling future for gaming enthusiasts. The emergence of devices that support Oculink could lead to gaming hardware that offers performance previously reserved for traditional desktop setups. With companies like Asus exploring Thunderbolt 5 eGPUs, we may soon see a seamless gaming experience that accommodates both handheld and desktop modes.
