HPE Xeon Gold 5415+ server processor

The HPE P49597-B21 is an eight-core Xeon Gold 5415+ CPU built for single- and dual-socket servers that need consistent throughput on database, virtualization or high-performance computing workloads. It fits the LGA-4677 platform and runs at a 2.90 GHz base frequency with a 4.10 GHz maximum turbo speed.

Sustained load behaviour

With a 150 W thermal design power the processor maintains its clock rates during extended multi-threaded runs rather than throttling after short bursts. The 22.50 MB L3 cache and 16 MB L2 cache keep frequently used data close to the cores, reducing memory latency when all sixteen threads are active.

Upgrade context

This part replaces an older Xeon Scalable processor on the same LGA-4677 socket when the workload demands DDR5 4400 memory support and the 10 nm architecture’s higher instructions-per-clock. The jump is worth it for environments that can use the extra cache and core count but do not require integrated graphics.

Questions about this item

What is the power draw of the Xeon Gold 5415+ when it runs continuously at full load?

The processor has a 150 W rating, which represents its typical thermal design power under sustained workloads.

Does the HPE P49597-B21 require DDR5 memory modules to operate?

Yes, the integrated memory controller is specified for DDR5 4400, so DDR5 modules are required.

Can I keep using my existing PCIe add-in cards with this Xeon Gold 5415+ upgrade?

The processor provides standard PCIe lanes for add-in cards; compatibility depends on your motherboard's slot layout and firmware.
