OCTEON III CN7XXX Multi-Core MIPS64 Processors

The OCTEON III CN7XXX family of Multi-Core MIPS64 Processors provides up to 120GHz of 64 bit processing and targets high-performance, high-throughput, service-rich applications for Cloud, Secure Datacenter, Wireless Infrastructure, Enterprise and Storage equipment. The family includes a range of software compatible processors, with up to 48 cnMIPS64 III cores, over 500 application acceleration engines including integrated high-performance search processing leveraged from Cavium’s NEURON Search processors, chip-to-chip interconnect and an innovative real-time PowerMin™ power manager, providing the highest compute and services performance of any standard ISA processor.

OCTEON III supports over 100Gbps of application processing in a single chip and supports multiple DDR3/4 channels and over 500 Gbps of I/O connectivity and the latest standards-based SERDES I/Os including 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 to higher performance 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.

The CN7XXX processors offer the highest compute for demanding 4G/LTE infrastructure applications, high-end security platforms, switch/router services blades, and high-performance appliances. With configurable SERDES, up to 4 DDR3/4 memory controllers, a large L2 Cache, and complete application acceleration, including NEURON Search, packet processing, Encryption/Decryption, Deep Packet Inspection (RegEx), Compression/decompression, De-duplication, RAID, and Multi-core scaling, the CN7XXX offers both the highest compute available as well as the highest throughput processing and services.

Powerful control plane processing solutions are enabled with high-frequency cores up to 2.5GHz, large and highly-associative L1 and L2 caches, and enormous DRAM bandwidth.

Using a 28nm process and innovative power saving technology, the CN7XXX offers 2X to 5X performance, power, and real-estate advantage over alternatives. The OCTEON III is supported by industry-standard software tool chains and operating systems, and is fully software compatible with the OCTEON II, OCTEON Plus and OCTEON families, enabling straightforward software reuse and scalability from 1 to 48 cores with the same software design.
