About REALTEK
Realtek has grown into one of the world's leading IC design companies, with product lines spanning communications networks, computer peripherals, multimedia, and other core technology domains.
Why Choose REALTEK
Realtek's core strengths lie in its comprehensive product portfolio, leading R&D capabilities, and unwavering commitment to high performance, low power consumption, and exceptional cost-effectiveness. The company's product lines fall into three main categories:
In communications network ICs, Realtek is the global market leader, commanding approximately 70% of the worldwide network IC market share. Products include Ethernet Network Interface Controllers (NIC), Physical Layer Transceivers (PHYceivers), network switch controllers, gateway controllers, wireless LAN ICs, and xDSL/VoIP controllers. Realtek continues to lead innovation in Ethernet technology, offering full-speed solutions covering 10/100/1000M, 2.5G, 5G, and 10G. The 2.5GbE Ethernet controller delivers ultra-low power consumption below 700mW in a compact 6x6mm² package, making it the industry's most power-efficient solution; the 5GbE single-chip Ethernet controller, housed in an 8x8mm² QFN package with power consumption under 1.5W, is the world's smallest and most energy-efficient 5GbE solution. In wireless communications, Realtek offers full-series IEEE 802.11a/b/g/n/ac/ax wireless LAN chipsets, and in 2026 launched Wi-Fi 8-enabled Wi-Fi 7 router solutions and the RTL8922D wireless network chip.
In computer peripheral ICs, Realtek provides traditional AC'97 audio codecs, high-definition audio codecs, card reader controllers, clock generators, USB bridge chips, and IEEE 1394 ICs. Realtek's audio codecs, renowned for high signal-to-noise ratios and exceptional sound quality, are widely adopted by major global motherboard, notebook, and audio device brands.
In multimedia ICs, Realtek's offerings include LCD monitor controllers, LCD TV controllers, digital media processors, video interface chips, and system-on-chip (SoC) solutions. In 2015, Realtek launched SoC technology supporting Dolby Vision™.
Realtek adheres to the philosophy of "new technology, new products, new applications, new value, and new markets". Through highly integrated designs, the company delivers innovative, fully-featured, high-performance, low-power, and cost-competitive total solutions. Realtek became the first IC design company in Taiwan to achieve ISO 9001 certification in 1995, and further obtained ISO 14001 environmental management certification in 2006.
