OCTEON III CN7XXX Family of Multi-Core MIPS64 Processors

High-performance, high-throughput, service-rich applications for cloud, secure data center, wireless infrastructure, enterprise and storage equipment

OCTEON III CN7XXX Multi-Core MIPS64 Processors

The OCTEON® III CN7XXX family of multi-core MIPS64 Processors provides up to 120GHz of 64bit processing and targets high-performance, high-throughput, service rich applications for cloud, secure data center, wireless infrastructure, enterprise and storage equipment. The family includes a range of software compatible processors, with up to 48 cnMIPS64 III cores. It has over 500 application acceleration engines including integrated high-performance search processing leveraged from NEURON Search processors. Chip-to-chip interconnect and an innovative real-time PowerMin™ power manager, provides the highest compute and services performance of any standard ISA processor.

OCTEON III supports over 100Gbps of application processing in a single chip.  It includes multiple DDR3/4 channels and over 500 Gbps of I/O connectivity and the latest standards-based SERDES I/O with multiple ports of 40G, 20G, 10G, GE, Interlaken/LA, SRIO, PCIe Gen3, SATA 6G and USB 3.0. With comprehensive HW virtualization support, OCTEON III is an ideal choice for network functions virtualization (NFV) and software defined networking (SDN) equipment.

OCTEON III also features a revolutionary, low latency coherent multi-socket architecture that enables multiple OCTEON III SoCs to appear as a single logical high-performance processor providing scalability and connectivity. The CN7XXX offers up to 4X performance over our market share-leading OCTEON II in a similar power envelope and up to 2x performance per Watt advantage over alternative solutions.
