I recently had the opportunity to thoroughly test the UGREEN Cat 8 Ethernet Cable (model number 30799), a 15-meter braided shielded cable promising speeds up to 40Gbps and a 2000MHz bandwidth. My goal was to see if this cable lives up to its claims in real-world scenarios, especially for demanding tasks like online gaming and high-bandwidth streaming.

The UGREEN Cat 8 cable boasts several impressive features. Its high bandwidth and data transfer rate are its main selling points, significantly exceeding that of previous Cat standards. The double-braided design feels robust and durable, surviving numerous bend tests during my evaluation. The RJ45 connectors are well-constructed and feel secure, and the included dust caps are a welcome addition.

I conducted several speed tests using a variety of devices, including a high-end gaming PC, PS5, and a 4K Smart TV. The results were impressive. In my gaming PC setup, I consistently saw download speeds that maxed out my internet connection, leaving no doubt the cable was not a bottleneck. Streaming 4K content to my Smart TV was flawlessly smooth, with zero buffering or lag. Even with the PS5, known for its high bandwidth requirements, the cable performed flawlessly.

Beyond pure speed tests, I paid close attention to stability. The double-shielding significantly minimized interference, even with other cables running nearby. There were no noticeable dropouts or connection issues during my extended testing period. The cable’s length proved convenient, allowing me to place my router strategically while still maintaining a solid connection.

Pros:

• Blazing-fast 40Gbps speeds
• Robust and durable construction
• Excellent interference reduction
• Wide compatibility
• Long length (15m)

Cons:

• Price point may be higher than some Cat7 cables
• Thickness might be a slight inconvenience for tight spaces

The UGREEN Cat 8 Ethernet Cable (30799) is a top-tier cable that delivers on its promises. The high speed, excellent stability, and robust build quality make it an ideal choice for anyone who demands the best possible network performance. While it is a bit more expensive than some Cat7 options, the substantial performance improvement justifies the cost for users with high-bandwidth needs. I wholeheartedly recommend it for gamers, streamers, and anyone who requires a fast and reliable network connection.
