Marvell brings its new Octeon DPUs on a 5nm node

The Octeon 10 series is one of the first to launch the ARM Neoverse N2 core.

Cavium, the creator of the Octeon product line, was acquired by Marvell back in 2018, which did not go too far with the TX2 design for the successor to the Octeon TX, but it was largely an acquired development, meaning they had little say in the final specifications. However, the new generation of Octeon is already largely the fruit of Marvell’s work, and it shows that the company has tried to innovate in as many places as possible.


Octeon 10’s most important advancement is that it is made on the TSMC’s 5 nm node, in addition to using Neoverse N2 cores based on ARMv9 architecture. Thanks to these, the overall program execution performance of the system on a thread is up to three times higher than its predecessor. Such progress speaks for itself, but the line of innovations is not over yet, as the new system chip will support PCI Express 5.0, use DDR5 memory, and have various accelerators that are available for DPUs (data processing units). particularly important. Among other things, tasks related to the cryptographic and machine learning deduction phases can be accelerated, but it is also important to accelerate the hardware of the VPP. Thanks to the latter, the speed of packet processing is radically improved, and these systems can also operate virtualized.


Marvell has four different series for the Octeon 10 product family, the main differences of which are detailed in the table below:
