The wait is over for PC builders looking to equip their machines with blazing-fast wired internet connections. RealTek has finally launched its line of RTL8126 5Gbps Ethernet adapters, first announced at Computex way back in 2023. These adapters promise significant speed improvements over the standard Gigabit Ethernet (1Gbps) commonly used today. The news comes at a time when the market is seeing an influx of super cheap, super fast 5Gbps Ethernet adapters. This raises the question of whether Gigabit Ethernet is becoming obsolete outside of business applications.

RealTreck ethernet adapters are actually very affordable

Priced competitively, the first RealTek adapter, a 5,000Mbps Networking Card B+M Key to PCIe adapter, is available on Amazon for $27. An ethernet adapter is a device that allows a computer to connect to a wired network using an ethernet cable. It essentially translates the signal from your computer into a format compatible with the ethernet network, and vice versa. This provides a more stable and reliable internet connection compared to Wi-Fi.

This budget-friendly option makes it accessible for users building high-performance PCs without breaking the bank. Compatibility is broad, with the adapter working seamlessly with Windows 7, 8, 10, and 11. While aesthetics may not be the top priority for an Ethernet adapter, it plays a crucial role in maximizing a PC’s potential. RealTek’s offering caters to those seeking the best possible components for their ultimate workstation builds, ensuring a smooth and efficient wired internet experience.

How do they perform?

It’s important to note that information about the adapters is still limited online. Some Reddit users have pointed out that similar adapters from Intel are available on eBay at competitive prices. Performance-wise, reports suggest promising results. According to CNX Software, a user achieved transfer speeds of 4.7Gbps in both directions with a similar card. However, speeds dropped to around 3.4Gbps when using PCIe Gen2 mode.

Overall, RealTek’s new line of 5Gbps Ethernet adapters presents a compelling option for PC builders seeking a significant performance boost in their wired internet connection at an attractive price point. This launch coincides with a broader market trend of affordable, high-speed Ethernet solutions, potentially signaling a shift away from Gigabit Ethernet as the standard, particularly for high-end PC builds.
