Realtek Unveils New 10 Gbps Ethernet Solutions to Enhance Cost-Effective Networking Options

Realtek has introduced a series of advanced 10 Gbps Ethernet solutions at Computex 2025, enhancing its portfolio with the RTL8127 PCIe controller, RTL8159 USB 3.2 controller, and RTL8261C PHY for switches. These products aim to provide efficient and cost-effective networking options for various applications.

RTL8127 PCIe Controller #

The RTL8127 is designed for high-speed networking with support for multiple Ethernet speeds, including 10 Mbps, 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps. It features a PCIe Gen4 host interface and includes capabilities such as modern standby and self-loopback diagnostics. With a power consumption of only 1.95 Watts, the RTL8127 promises to lower cooling costs, potentially saving users on heatsink expenses.

The RTL8127 will be available in PCIe and M.2 formats or can be integrated directly onto motherboards and customer premises equipment (CPE). Variants such as the RTL8127AP and RTL8127ATF cater to specific market needs, including server management and fiber-only applications.

RTL8159 USB 3.2 Controller #

Realtek’s RTL8159 controller supports the same Ethernet speeds as the RTL8127 and utilizes a USB 3.2 Gen2 x2 host interface. It is designed for integration into USB Ethernet adapters, hub monitors, and docks. This controller offers features like CDC-NCM compatibility and hardware support for Receive Side Scaling (RSS).

RTL8261C PHY #

The RTL8261C PHY is tailored for 10GbE switches and supports various Ethernet standards, including 10GBase-T and 5GBase-T. With multiple interface options, it is suitable for a wide range of networking equipment, including 5G customer premises equipment and WiFi 6/7 routers.

Pricing and Availability #

While specific pricing details have not been released, it is anticipated that the new 10 Gbps solutions will be priced competitively, likely between $30 and $40, based on the current pricing of Realtek’s 5 Gbps products. The market can expect to see the first wave of cards and motherboards featuring the RTL8127 by Q4 2025, with additional options becoming available throughout 2026.
