Intel Xeon Gold 6554S 36-core server processor

The Intel Xeon Gold 6554S is a 36-core, 72-thread server CPU built on 10 nm process technology. It operates at a 2.2 GHz base frequency with a maximum turbo frequency of 4.0 GHz. The processor includes 180 MB of L3 cache and supports 64-bit processing. It is designed for demanding data centre, multi-cloud compute, network and storage workloads.

Compatibility checks before ordering

Verify that your server motherboard uses the LGA 4677 socket and supports a 270 W thermal design power. Confirm the platform provides eight memory channels to reach the rated 5200 MHz integrated memory controller speed. Ensure the system can accommodate up to 4 TB maximum memory capacity and PCI Express 5.0 with up to 80 lanes for your expansion cards. Check that your chassis and cooling solution are rated for this processor class.

Who this suits and who should look elsewhere

This processor suits operators running two-socket scalable servers for virtualization, database and high-performance computing tasks needing high core counts and large memory bandwidth. Buyers who need four-socket scalability beyond the 2S limit should evaluate other models. Deployments requiring lower power consumption or fewer cores for lighter workloads should consider different SKUs. Systems without LGA 4677 infrastructure cannot use this CPU.

Questions about this item

Does the Intel Xeon Gold 6554S ship with a heatsink or thermal interface material, or must those be sourced separately?

The processor is sold as a tray unit without a heatsink or pre-applied thermal paste; a compatible LGA 4677 cooler rated for 270 W must be purchased separately.

When should I choose the 6554S over other 36-core Xeon Gold models?

Select the 6554S when your workload needs 2.2 GHz base frequency, 4.0 GHz max turbo, 180 MB L3 cache and 80 PCIe 5.0 lanes within a 270 W envelope for two-socket scalability.

What does the 2.2 GHz base clock mean once the CPU is installed in a server?

It guarantees a sustained 2.2 GHz across all 36 cores under full load within the 270 W TDP, while turbo can lift active cores to 4.0 GHz when thermal headroom allows.
