'''ThunderX2''' is a family of {{arch|64}} [[multi-core]] [[ARM]] server microprocessors introduced by [[Cavium]] in early [[2018]] succeeding the original {{\\|ThunderX}} line.

== Overview ==
The ThunderX2 was designed to succeed the original {{\\|ThunderX}} family. [[Cavium]] first announced the ThunderX2 back in May 30 2016 with models based on their own {{cavium|thunderx2|second-generation|l=arch}} microarchitecture with models up to 54 cores. Cavium focused the {{\\|ThunderX}} design on the networking space as the {{\\|Octeon TX}} family, and in late 2016 they acquired the {{cavium|Vulcan|l=arch}} design from [[Broadcom]] which has designed a server microprocessor but has given up on the project for reasons not well understood. In early 2018, Cavium announced that their ThunderX2 processors (now based on {{cavium|Vulcan|l=arch}}) have reached general availability.

== Models ==
=== CN99xx ===
{{see also|cavium/microarchitectures/vulcan|l1=Vulcan microarchitecture}}
The first parts of the ThunderX2 family, CN99xx series, that made it to general availability are based on the {{cavium|Vulcan|l=arch}} microarchitecture. Those parts are different from Cavium's original ThunderX2 design which started sampling in 2016. Originally designed by [[Broadcom]], those parts have much higher performance and a slightly different set of features. All parts have the following features in common.

* '''Mem:''' Up to 2 TiB of quad/hexa/octa- channel DDR4 2666 MT/s memory
** Up to 4 TiB in dual-socket configuration
* '''ISA:''' [[arm|ARMv8.1]], 128-bit {{arm|NEON}} SIMD
* '''I/O:''' x48, x56 PCIe Gen 3 Lanes
* Only the [[arm/aarch64 | 64-bit AArch64]] execution state is support. No [[arm/aarch32 | 32-bit AArch32]] support.
