HPE Xeon Gold 5420+ 28-core server processor
This HPE server processor is an Intel Xeon Gold 5420+ with 28 cores and a 2 GHz base clock. It delivers 56 threads and 52.50 MB of L3 cache for multi-threaded workloads. The CPU fits the LGA 4677 socket and supports DDR5 memory at 4.40 GHz. Thermal design power is rated at 205 W.
Suited for dense virtualisation and heavy compute
The 28-core design and 56 threads suit virtualisation hosts, database nodes and render farms that need high core counts. Intel Virtualization Technology and Trusted Execution Technology are included. Buyers who need lower power draw or fewer cores for lighter tasks should consider other options. The 205 W TDP requires robust server cooling infrastructure.
LGA 4677 socket and 205 W TDP define compatibility
This processor only works with motherboards that provide an LGA 4677 socket and can handle a 205 W thermal design power. The 52.50 MB L3 cache and 4.10 GHz maximum turbo frequency are fixed specifications. Verify that your server platform supports the LGA 4677 package and the required power delivery before purchase.

Questions about this item
What is the thermal design power of the Xeon 5420+ and how does it affect cooling requirements?
The processor has a 205 W thermal design power, so the server chassis and cooler must be rated to dissipate at least that much heat continuously.
Which limit appears first when the 28-core CPU runs at full load for extended periods?
The 97 °C thermal specification is the first hard limit; sustained workloads will throttle once the die reaches that temperature.
How loud and hot does the 5420+ get when it runs all day in a typical server?
At 205 W TDP the chip produces significant heat; fan noise depends on the chassis airflow design, but expect active cooling to run at higher speeds continuously.
