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

SKU CH-974K-RC4VH MPN PK8071305554700

A 12-core, 24-thread server CPU with 22.5 MB cache and a 115 W TDP for scalable workloads

  • ColorGray
  • Weight2.0000
  • 12 cores and 24 threads handle parallel workloads efficiently
  • Base frequency of 2 GHz provides steady compute performance
  • Max turbo frequency reaches 3.9 GHz for burst speed
  • 5 MB cache reduces latency for data-intensive tasks
  • 115 W TDP balances power draw with processing capacity

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.

Questions about this item

How loud and hot does the Xeon Gold 5403N run under continuous 115 W load?

The processor has a 115 W TDP, so sustained full-load operation will require a server-grade cooler and chassis airflow rated for that heat output.

What socket and platform pieces must I already own to install the PK8071305554700?

It fits an FCLGA4677 socket and needs a compatible server motherboard, memory, and power delivery designed for this Xeon.

Will the 5403N work in my older dual-socket board that still uses UPI links?

This model has 0 UPI links and 0 GT/s UPI speed, so it cannot participate in multi-socket configurations.
