With over thirty years of experience in development of PHY and MAC chip technologies, over hundreds of network communication patents, and abundant market experiences, Realtek built a 2.5G Ethernet products with the smallest package, the lowest power consumption, the most reliable networking solutions around the world. It is the best choice of implementation for PC makers and network users.
Network communication is essential to transmission media in modern life. Specifications and speed of Wi-Fi6E and 5G have been enhanced continuously. The speed of wired Ethernet devices have been evolved from gigabit to 2.5gigabit for consumer market.
In contrast to faster Ethernet devices, network wiring (Cat 5e network cables) for 1GbE can also be used for 2.5GbE, immediately upgrading the 2.5G Ethernet devices to 2.5 x network speed. The cost of the chip and the cost of the network device supported by the chip are more acceptable to typical consumers, suitable for business and home computer market, and easier for popularization.
Gamers, self-media workers and remote workers are most benefitted from the new generation of Realtek 2.5G Ethernet (LAN)
Business environment has been relied on network communication tools increasingly up to now since Covid-19. WFH (Work from Home) could become the common working style in future. When people are working, online meeting, the percentage of collaboration platforms requiring zero-time difference and online interaction grows significantly. Communication quality through wireless network can easily suffer from interference from other devices to cause lag or even randomly disconnected due to far distance and obstacles. People need reliable Ethernet solutions to solve the problem. Bloggers and VTubers often need to edit and upload videos, download materials, backup data for their work, and interact with others by video communication software. The time it takes to send and receive large files is the biggest challenge to working efficiency. It is imperative to increase network bandwidth. Typical gamers play online games. Game streamers must use streaming software or other network applications to increase views while playing games. With more and more network applications, it is required to increase the bandwidth and choose NICs not only with high speed, but stable connection and lowest gaming latency. Realtek 2.5G Ethernet solutions offer a stable, excellent, high speed network experience without speed drop or missing package.

Realtek (wired) Ethernet application
The era of fast Extranet is coming. Enjoy a lifestyle with high performance by Intranet transmission 2.5 times faster.
Wireless network has been updated to Wi-Fi 6E. End-users gradually upgrade wireless routers to the ones with Wi-Fi 6E and 2.5GbE ports. Network speed cannot be increased by solely upgrading the wireless router. The bandwidth of the overall network environment must be enhanced at the same time. Interfacing devices such as NIC and switch must be all upgraded to 2.5G to achieve 2.5GbE ecosystem.
Support diverse applications with fast network speed
2.5GbE can be widely used for the motherboard, NAS, multi-gigabit switch, AP routers, PCIe network cards, USB-to-RJ45 dongles and docks. Realtek is the first IC design house providing 2.5GbE USB NIC solutions, which can be used for thin business laptops that need Ethernet (RJ45) despite that NIC has been removed, and network speed upgrade for computers via USB-A and USB-C port. Furthermore, Realtek 2.5GbE solutions are suitable to broadband devices for ISP such as cable modems, xDSL, optical xPON and telecom end devices.
The advantage of the second generation of Realtek 2.5G Ethernet products
PCIe, USB and PHY, the three major 2.5GbE series satisfying the needs of various network devices and target audience groups. Second generation has smaller package, lower power than the prior generation products.
With over 30 years of experience in developing excellent technology of network chips, Realtek PHY and MAC chips have an extremely high market share. The first generation of 2.5GbE solution is highly praised. Realtek surpassed the previous performance and launched the second generation of 2.5Gbe Ethernet chip products: RTL8125B-CG series/RTL8156B-CG series/RTL8221B-CG series, expecting to provide customers with better products. The primary advantages of the second generation of 2.5GbE are as follows:
- Size reduced by 64%
The QFN package is smaller than its predecessor. Small size reduces the cost of production and great for small mobile devices meeting the market need for higher speed mobile network.
2. Power consumption lower by 50% for environmental friendliness:
More regulations are coming to define a mandatory energy efficiency standard for PCs – including desktops, AIOs with high-speed networking capability and mobile gaming systems for reducing carbon. Realtek second generation 2.5GbE solution only take 0.65 Watt while 2.5Gbps transmitting and receiving at chip level (the performance result depends on the DUT configurations) to comply with EEE standard.
3. High speed, stability and compatibility:
Professional network test tools proved that these products maintain stable, high speed two-way transmission (upload and download) when connecting to major network switches in the market. The products support stable transmission for network cables 10% longer than the standard ones: IEEE802.3bz defined that 100 meters is the standard length of 2.5GbE supported Cat 5e network cables. Realtek can support network cables with 110 meters. Network quality will not be hindered by cable length tolerance. Outstanding performance can be maintained even if network cables are cascaded in different sections. Performance stays high even with complicated network cable cascading.
4. Co-lay design and painless upgrade:
Most of the customers have been using the Realtek 1GbE solution for years. 1GbE solution is still the mainstream in the motherboard market. To correspond to potential market needs and sustain the advantages of the predecessor, stable and high speed and compatibility, the second generation of 2.5GbE Ethernet chips adopt the Co-lay design. Customers of specific Realtek 1GbE solution (RTL8111K-CG series) save the time designing new circuit boards and speed up the network speed by 2.5 times without altering the previous design. Network communication suppliers can plan for their products according to the service life of different products flexibly. It is convenient for customers on market planning.
Dragon is the exclusive network bandwidth control manager for end users, optimizing the user’s online experience (RTL8125BG-CG series and RTL8156BG-CG series)
Dragon is a network optimization software developed by Realtek. By hardware and software collaboration, Dragon outshines the performance of to other bandwidth control software in the market. The exclusive technology “Rx high priority” (RTL8125BG-CG series only) acquires a fast pass for the most important application to users while multi-tasking. It received the network packages classified as high priority from NIC to the operating system immediately, saving the response time and significantly increasing the processing speed of the most prioritized application.
Software automatically optimizes the bandwidth distribution of numerous applications online based on the end user needs without speed test. Dragon AI detects the bandwidth spontaneously and differentiates the types of network applications automatically. Modes for different purposes such as gaming, drama, network browser and working are available. It is easy to use without complicated operations or settings. Dragon ensures smooth operation of the network application that the users care about the most.
Dragon AI: Bandwidth control software with AI technology automatically detects the maximum bandwidth of the user’s network without testing the speed. It provides intuitive, easy-to-use user interface and software.
Rx High Priority: The hardware patented technology of Realtek 2.5G Ethernet provides a “fast pass” to online applications with the highest priority and speeds up the time that the user receives the processed network data.
R-rowStorm: It assigns priority to ensure smooth operation of numerous applications online. If multiple NICs with Realtek Dragon are available, hidden functions can be unlocked.
On the computer platform that have numerous NICs with Dragon support available, the software unlocks “R-rowStorm” in the hidden area automatically. Division of network applications can be carried out by one click. If numerous external network services are provided for expanding the network bandwidth available on the platform, users can use multiple NICs instead of one and enjoy smooth network experiences. For instance, the built-in 1G NIC on the platform is used with USB NIC and Wi-Fi to upgrade the network to 2.5G. (Note: The NIC must be able to support Dragon.)
