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 realtime 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 over 500 Gbps of I/O connectivity and the latest standards-based SERDES I/O’s including multiple ports of 40G, 20G, 10G, GE, Interlaken, Interlaken/LA, SRIO, PCIe Gen3, SATA 6G and USB 3.0.

OCTEON III also features a revolutionary, low latency coherency architecture that enables multiple OCTEON III chips to appear as a single logical high-performance processor with up to 384 cores, providing up to 960GHz compute, up to 800+ Gbps of application performance and up to 2 Terabytes of memory capacity. 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, switch/router and ATCA blades, and high-performance appliances. With configurable SERDES, up to 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.
