Broadcom Corp. has introduced what it boasts as the industry's first 64bit quad-core processor for high-end routers. The BCM4908 enables OEMs and service providers to deliver the extra CPU power needed for smart home and Internet of Things (IoT) applications while unleashing the higher Internet speeds coming into the home, indicated the company.

The BCM4908 includes the industry's first 1.8GHz 64bit quad-core ARM CPU and uses Broadcom's Runner network packet processor to deliver more than 5Gb/s of system data throughput without taxing the CPU, stated the company. It also supports the increased speeds coming into the home including Google Fibre and Comcast 2Gb/s via an interface for a 2.5 Gigabit Ethernet PHY, allowing consumers to enjoy the fastest connection available.

The BCM4908 pairs with Broadcom's BCM4366 wave 2 5G WiFi MU-MIMO to deliver more than 3.4Gb/s of simultaneous WiFi throughput.

The quad-core processor features zero CPU WiFi offload that frees up CPU resources for other tasks; BroadStream iQoS acceleration; dedicated security processor to enable hardware VPN acceleration; 2.5Gb Base-X Ethernet WAN/LAN port for supporting fast connectivity to multi-gigabit modem or a Network Attached Storage (NAS) device and feature-rich connectivity with integrated SATA III, two USB 3.0 ports and three PCIe Gen 2 ports reduces external RBOM cost.

The solution uses low power 28nm technology and advanced power management, offering power reductions of more than 50 per cent as compared to previous solutions. It also supports Broadcom's tri-band (AC5300) 5G WiFi XStream 802.11ac MU-MIMO: three BCM4366 4x4 radios, each with an integrated CPU for host offload processing, and providing a total of seven CPU cores (Septacore) with more than 9.6GHz of CPU horse power.

The BCM4908 is sampling.
