Distributor

Realtek Semiconductor Corp. (瑞昱半导体, TSE: 2379) is a fabless IC design company founded in 1987 and headquartered at Hsinchu Science Park, Taiwan. Realtek is one of the world's top 10 fabless semiconductor companies, ranking 7th globally by Omdia in 2024. The company designs and sells four main product categories: Ethernet controllers (PCIe Gigabit and 2.5GbE), wireless network ICs (Wi-Fi 5/6/6E/7 and Bluetooth combo chips), audio codecs (HD Audio codecs for PC and consumer electronics), and card reader controllers. Realtek's ICs are integrated into products from leading PC, networking, and consumer electronics brands worldwide, with annual revenue of NT$113.4 billion (2024) and over 7,200 patents.

For any Realtek product needs, contact BeiLuo Electronics, an authorized distributor since 2010.

Realtek and Intel Ethernet controllers serve different market segments. Realtek Ethernet controllers (RTL8111H, RTL8125B) are preferred for consumer motherboards, embedded systems, and cost-sensitive applications due to their excellent performance-to-cost ratio, broad OS driver support, and lower power consumption. Intel Ethernet controllers (I210, I225) are typically chosen for enterprise servers, data centers, and mission-critical applications where advanced features like SR-IOV, TCO, and iSCSI boot are required. For the vast majority of consumer PC, industrial, and SMB networking applications, Realtek offers more competitive pricing with perfectly adequate performance and reliability. For enterprise server deployments requiring advanced management features, Intel may be the preferred choice.

Choose Realtek for consumer, embedded, and cost-sensitive designs. Choose Intel for enterprise servers with advanced management requirements.

Wi-Fi 6 (802.11ax) operates in 2.4GHz and 5GHz bands, offering up to 9.6Gbps theoretical throughput with OFDMA and MU-MIMO technologies. Wi-Fi 6E extends Wi-Fi 6 into the 6GHz band, adding 1200MHz of new spectrum for reduced interference and higher throughput. Wi-Fi 7 (802.11be) is the next-generation standard featuring 320MHz channel width (double Wi-Fi 6), 4096-QAM modulation, Multi-Link Operation (MLO), and theoretical speeds up to 46Gbps. Realtek offers solutions across all three standards: RTL8852BE (Wi-Fi 6), RTL8852AE/RTL8852CE (Wi-Fi 6E), and is developing Wi-Fi 7 solutions for next-generation applications.

Choose Wi-Fi 6 for current mainstream applications. Consider Wi-Fi 6E for newest flagship designs. Evaluate Wi-Fi 7 for future-proof high-bandwidth applications.

Choosing the right Ethernet controller depends on your interface, speed, and application requirements. For standard desktop PC motherboards, RTL8111H (PCIe Gigabit) is the most cost-effective choice. For industrial or embedded applications requiring wide temperature range, RTL8111EP-CG offers industrial grade support. For USB-based designs (dongles, docking stations), RTL8153B or RTL8156B provide Gigabit and 2.5GbE over USB 3.0 respectively. For internal 2.5GbE applications, RTL8125B is the ideal PCIe solution. For server or high-performance applications, evaluate multi-port and advanced feature controllers. All Realtek controllers support comprehensive Windows, Linux, and macOS drivers.

Start by determining interface (PCIe vs USB) and speed requirement (1GbE vs 2.5GbE), then select the appropriate RTL part number.
