Intel Xeon Gold 5403N 12-core 24-thread 2.0 GHz 22.5 MB cache PK8071305554700 server processor

12-core Xeon Gold for dense server builds

The Intel Xeon Gold 5403N delivers twelve cores and twenty-four threads at a 2.0 GHz base frequency with a 3.9 GHz maximum turbo. It fits the FCLGA4677 socket and carries 22.5 MB of cache within a 115 W thermal envelope. This processor targets rackmount and blade deployments that need steady multi-thread throughput rather than peak single-core speed.

Sustained multi-thread throughput at 115 W

Under continuous load the chip holds its all-core frequency within the rated 115 W envelope, avoiding the sharp throttling seen in higher-TDP parts. The 22.5 MB cache keeps working sets close to the cores, reducing memory latency during long compute windows. Zero UPI links mean the die is designed for single-socket systems, so scaling stops at one package.

Replaces older single-socket Xeons when UPI is not

The jump is worth it for operators moving from earlier Gold or Silver SKUs that required multi-socket UPI mesh but now run workloads that fit one socket. Buyers who need inter-socket coherency or more than twelve cores per node should look elsewhere, as this model exposes no UPI links and caps at twelve cores.
