This YouTube video, titled "RTX 5090 eGPU Test: Zotac Zone (USB4) vs. AYANEO 3 (OCuLINK) at 4K" by ETA Prime, tests the performance of the NVIDIA GeForce RTX 5090 eGPU with two handheld gaming PCs, the Zotac Zone and AYANEO 3, in 4K gaming.

Here are the key takeaways from the video:

Testing with Two Handhelds: The RTX 5090 eGPU was tested with the Zotac Zone (USB4 connection) and the AYANEO 3 (OCuLink connection).

Performance over USB4 (Zotac Zone): While the RTX 5090 works over USB4, there's a significant performance loss compared to a desktop setup due to bandwidth limitations. Some games were playable at 4K, especially older or well-optimized titles.

Performance over OCuLink (AYANEO 3): OCuLink, expected to be faster, offered only a marginal improvement (10-25 FPS) over USB4 in the tested games. It still didn't fully utilize the RTX 5090's potential.

Bandwidth and Drivers: The video concludes that the RTX 5090's performance with handhelds is limited by bandwidth and potentially driver issues. Newer drivers and further testing are needed.

4K Gaming Achievable but Limited: 4K gaming is possible on handhelds with the RTX 5090, but performance is not optimal, and the connection type (USB4 or OCuLink) doesn't make a massive difference in the tested scenarios.

The video suggests that while eGPUs like the RTX 5090 can work with handheld PCs, users should manage expectations regarding 4K gaming performance due to current bandwidth and driver limitations. ETA Prime plans further investigations with different setups and driver updates.

can i download the eGPU like how i download my ram?

The huge bottleneck lol. But if you got the money why not..

I haven't seen any hardware with Oculink irl

nanti terbakar, terbakar di luar casing.
not burn down whole PC or whole house....

cukur

that thing RUN cyberpunk like butter!

brilliant! lol

apsal dia pakai usb cable merah beli kat DIY tu

nothing speaks like throw money and scalp GPUs

Oculink > Thunderbolt 4

Thunderbolt 5 > Oculink ???

Yes, Thunderbolt 5 is indeed faster than Oculink. Thunderbolt 5 offers up to 80 Gbps of bi-directional bandwidth, while Oculink provides up to 64 Gbps. This makes Thunderbolt 5 the faster option in terms of data transfer speeds1.

However, it's important to consider the specific use case. Oculink is optimized for internal server and storage applications, offering lower latency and dedicated PCIe lanes, which can be beneficial for certain high-performance computing tasks. Thunderbolt 5, on the other hand, is more versatile and widely supported, making it a better choice for general-purpose use and compatibility with a wider range of devices2.

The latest Intel PCs featuring Thunderbolt 5 include high-end desktops like the Core Ultra Elite Desktop PC with dual Thunderbolt 5 ports. This PC is built around Intel's Core Ultra processors and is designed for enthusiasts and professionals who need top-tier performance1.

For Mac users, the new Mac mini and MacBook Pro models powered by the M4 Pro and M4 Max chips are the first to introduce Thunderbolt 5 connectivity. These models offer enhanced external display support and faster data transfer speeds2.
