Intel Xeon Gold 6544Y 16-core server processor

The Intel Xeon Gold 6544Y is a 16-core server processor built for dual-socket platforms. It runs at 3.6 GHz with a 4.1 GHz max turbo frequency and provides 32 threads for parallel workloads. The LGA 4677 package delivers 80 PCIe 5.0 lanes and an eight-channel memory controller at 5200 MHz.

45 MB L3 cache and 270 W TDP

A 45 MB L3 cache reduces latency for data-intensive applications. The 270 W thermal design power requires server-grade cooling and power delivery. The 10 nm manufacturing process supports 64-bit processing and hardware virtualization features.

Suited for two-socket data-centre deployments

This processor suits dual-socket servers handling virtualisation, database, or high-performance computing tasks. It is not intended for single-socket workstations or systems limited to lower memory capacities. Builds needing four-socket scalability or different core counts should evaluate other options.

Questions about this item

Does the 270 W TDP of the Xeon Gold 6544Y require a specific server-grade cooler and periodic thermal-paste replacement?

The processor has a 270 W thermal design power. A server chassis with adequate airflow and a heatsink rated for at least 270 W is required. Thermal paste should be inspected and replaced during scheduled maintenance intervals.

What thermal limit is reached first when the 16 cores sustain 3.6 GHz across all threads?

The 270 W TDP is the primary sustained-power limit. When all 16 cores run at the 3.6 GHz base frequency the package power will approach this ceiling, and the processor will manage frequency to stay within the thermal envelope.

How much fan noise and case heat should I expect from the 270 W Xeon Gold 6544Y during continuous operation?

At 270 W the CPU alone contributes significant heat to the chassis. Fan speed and acoustic output depend on the server cooling solution; a properly sized heatsink and high-flow fans are needed to keep temperatures stable under continuous load.
