RealTek unveiled a new range of RTL8126 5Gbps PCIe and M.2 Ethernet adapters at Computex 2023 (yes, last year), promising extremely fast wired Internet connections.
Those adapters are finally on sale, and at pretty reasonable prices too. The first module, available on Amazon for $27, is the B+M 5000Mbps Network Card for PCIe Adapters, which works with Windows 7, Windows 8, Windows 10, and Windows 11.
The adapter is ideal for those who are building their own PC and want to use the best PC parts to do so. While an Ethernet connection may not be the sexiest part of all, it's definitely important to get the most out of your setup.
Build your PC with freedom
An Ethernet adapter is just one component you'll need to build a top-of-the-line PC for gaming, pleasure, or business.
Unfortunately, there is currently only limited information about the adapters online, and some users on Reddit noted that equivalent adapters from Intel are listed on eBay for a fairly reasonable price.
According to CNX Software, a forum user tested a similar card and achieved transfer speeds of 4.7 Gbps in both directions, but speeds dropped to 3.43 Gbps (Rx) and 3.31 Gbps (Tx) in PCIe mode Gen2.
