# CPU compatibility matrix for Ubuntu Server and OpenStack

The CPU compatibility matrix for Ubuntu and related products. The matrix shows which Ubuntu LTS version introduces an initial support for a given processor or chipset. Canonical recommends running the latest LTS release to take advantage of the full capabilities of a CPU.

| Vendor | CPU family | Code name | Initial support in Ubuntu LTS |
| --- | --- | --- | --- |
| AMD | EPYC 7xx3 | Milan (Zen 3) | 18.04.5 |
| AMD | EPYC 7xx2 | Rome (Zen 2) | 16.04.5 |
| AMD | EPYC 7xx1 | Naples (Zen1) | 16.04.5 |
| Intel | Xeon | Ice Lake (SP) | 18.04 |
| Intel | Xeon | Cooper Lake | 18.04 |
| Intel | Xeon | Cascade Lake | 18.04 |

## Supported OpenStack versions

OpenStack release cadence follows Ubuntu release cadence. This means that a new version of OpenStack is released twice a year: in April and in October. Those are shipped with new versions of Ubuntu, however, since Canonical recommends using Ubuntu LTS in production environments, new versions of OpenStack are also available on Ubuntu LTS version through the [Ubuntu Cloud Archive](https://wiki.ubuntu.com/OpenStack/CloudArchive).

The OpenStack support lifecycle on Ubuntu can be represented this way:

| Release | Tech preview | Released | End of life | Extended customer support | Expanded Security Maintenance (ESM) |
