Description

The AMD EPYC 9565 Server Processor for HPE delivers 72 cores and 144 threads on AMD's 5th Generation Zen 5 architecture, making it one of the most capable processors available for HPE ProLiant Gen11 and Gen12 servers. With a 3.15GHz base clock boosting to 4.3GHz, 384MB of L3 cache, and a configurable 320–400W TDP, it is purpose-built for demanding enterprise workloads including virtualisation, HPC, AI/ML inference, analytics, and high-density data management.

The EPYC 9565 supports 12-channel DDR5 memory at up to 6400 MT/s, delivering 576 GB/s of per-socket memory bandwidth and up to 3TB RAM per socket. PCIe 5.0 with 128 lanes enables exceptional I/O throughput for NVMe storage and high-speed networking. Note: this processor does not include a heatsink or fan kit — a performance heatsink rated for processors above 240W must be ordered separately.

FAQs

Q: Which HPE server platforms are compatible with the P72651-B21 processor?
A: The AMD EPYC 9565 (P72651-B21) is compatible with HPE ProLiant Gen11 and Gen12 servers that feature the SP5 socket, such as the ProLiant DL385 Gen11 and similar dual-socket platforms. Always verify compatibility with HPE's QuickSpecs for your specific server model.

Q: Does this processor include a heatsink or fan kit?
A: No. The P72651-B21 is a processor-only option and does not include a heatsink or fan kit. Because the EPYC 9565 has a TDP above 240W, a performance heatsink and fan kit rated for high-TDP processors must be ordered separately.

Q: How many processors can be installed per server?
A: The EPYC 9565 supports both single-processor (1P) and dual-processor (2P) configurations, depending on the host server. In a 2P configuration, up to 144 cores, 288 threads, and 6TB of DDR5 memory can be deployed across both sockets.

Q: What workloads is the AMD EPYC 9565 best suited for?
A: The EPYC 9565 is optimised for virtualisation (VM density), high-performance computing (HPC), AI/ML inference, engineering simulation (CAE/CFD/FEA), enterprise resource management (ERM/SCM/CRM), analytics, and high-capacity data management — all benefiting from its 72 cores, massive L3 cache, and high memory bandwidth.

Q: Can I purchase the HPE AMD EPYC 9565 P72651-B21 in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller offering the HPE P72651-B21 with delivery Australia-wide. Contact the team for volume pricing, lead times, or compatibility advice.

Q: What is the difference between the configurable TDP options on this processor?
A: The EPYC 9565 supports a configurable TDP range of 320W to 400W. Lowering the TDP allows deployment in thermally constrained environments at the cost of some peak performance headroom. The default TDP is 400W, which delivers maximum sustained performance for intensive enterprise workloads.
