Broadcom Continues Market Leadership with over 100 Million NetXtreme(R), NetXtreme II and NetLink(TM) Gigabit Ethernet Controllers Shipped to Date

20 January 2006

Broadcom Corporation (Nasdaq: BRCM), a global leader in wired and wireless broadband communications semiconductors, today announced that it has shipped over 100 million Gigabit Ethernet (GbE) controller chips to date, demonstrating its leadership in the GbE LAN-on-motherboard (LOM) market. According to Dell'Oro Group market research, Broadcom continues to maintain its number one position in GbE units shipped for the 6th quarter in a row, with more than three times the market share of its next closest competitor.

Having led the PC industry migration from Fast Ethernet (FE) to Gigabit Ethernet, Broadcom(R) NetXtreme(R), NetXtreme II and NetLink(TM) GbE controllers continue to be the chips of choice for servers, enterprise desktops and notebooks for leading personal computer manufacturers and other customers worldwide.

Leading the charge in next generation enterprise servers is Broadcom's NetXtreme II family of converged network interface controllers (or C-NICs) designed to drastically change the way servers are built and deployed in the future. This family of single-chip C-NIC devices simultaneously runs three specific functions including accelerated TOE (TCP offload engine) for data networking, accelerated iSCSI for block storage networking and accelerated RDMA (remote direct memory access) for high-performance server clustering - all over a single Ethernet fabric. By converging disparate network traffic over Ethernet, Broadcom NetXtreme II C-NICs enable a lower total cost of ownership (TCO) relative to configuring, maintaining and running three separate and disparate networks.

Broadcom's NetXtreme controllers led the migration in the personal computing industry worldwide from FE to GbE and continues to provide unmatched industry-first solutions. For example, Broadcom introduced the first GbE controller based on PCI Express(R) that overcame speed bottlenecks typically associated with legacy PCI buses, as well as the first Trusted Platform Module 1.2 GbE controller enabling PC manufacturers to offer this high level of security as a standard feature.

Broadcom's NetLink family of GbE controllers is optimized for consumers and small-to-medium-sized businesses (SMBs). Poised to redefine new uses for the PC that enable compelling and exciting SMB and consumer applications, such as video editing and file transfer, LAN gaming, video conferencing, multimedia data sharing and desktop management, the NetLink GbE controller family provides the optimal balance of cost-effectiveness, reliability and low power consumption.

"By maintaining close working relationships with industry leaders, and focusing on execution towards a common vision, Broadcom continues to deliver the next generation technology that our partners and their customers demand," said Greg Young, Vice President & General Manager of Broadcom's High-Speed Controller Line of Business. "This milestone validates our leadership position in wired communications and proves that we are well-positioned to maintain this leadership when we deliver our next generation products for the digital home and office, including 10GbE solutions."
