OCTEON® III CN77XX Processors

OCTEON® III CN77XX 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.

The OCTEON® III CN77XX family of Multi-Core MIPS64 Processors builds on the award-winning OCTEON II family, with a higher number of improved cnMIPS64 cores, wider range of I/O, higher application acceleration for networking, security and storage, larger caches, latest interfaces such as DDR4 and PCIe Gen3. The family includes two software and pin-compatible processors, with 16 to 24 cnMIPS64 v3 cores running at up to 2.5GHz, rich hardware virtualization compliant with MIPS64 Release 5, multiple DDR4 and DDR3 channels and over 100Gbps of application acceleration performance. Along with OCTEON III CN78XX family, CN77XX provides highly scalable processor solutions from 16 to 48 cores. Built on high-performance low-leakage 28nm process technology, along with on-chip power gating and a real-time power optimizer, this family delivers the highest compute and services performance at lowest power consumption.  The CN77XX family provides extremely high-bandwidth connectivity based on the latest standards-based SERDES I/Os including XLAUI, PCIe Gen3, XAUI, Double-speed XAUI, XFI/KR, RXAUI, and Interlaken/LA.
