Description

The HPE-certified AMD EPYC 9455 server processor delivers 48 cores and 96 threads at a 3.15 GHz base clock (boosting to 4.4 GHz), with a 300W TDP designed for demanding enterprise workloads. Built on AMD's 5th Generation EPYC 9005 Series architecture, it supports 12-channel DDR5 memory at up to 6400 MT/s and PCIe 5.0 x128 lanes, making it an ideal choice for virtualisation, large-scale databases, and high-performance computing on HPE ProLiant Gen11 platforms.

Compatible with HPE ProLiant DL365 Gen11, DL385 Gen11, and ProLiant Compute XD685 servers, this processor kit features a chipset-free SoC design and 256 MB of L3 cache for ultra-fast data access. A performance heatsink and fan kit are required and sold separately for this 300W configuration. Upgrade your network with gear from iptrading.com.au — Australia's IT hardware specialists.

FAQs

Q: Which HPE servers is the P72654-B21 AMD EPYC 9455 processor compatible with?
A: The P72654-B21 is certified for HPE ProLiant Gen11 platforms, including the ProLiant DL365 Gen11, DL385 Gen11, and ProLiant Compute XD685. Always verify the HPE QuickSpecs for your specific server model before ordering.

Q: Does the processor kit include a heatsink and cooling fans?
A: No. The processor kit is sold separately from the heatsink and fan kit. Because the EPYC 9455 operates at 300W TDP, an HPE performance heatsink and fan kit is required and must be purchased separately.

Q: How much memory can the EPYC 9455 support per socket?
A: The processor supports up to 3TB of DDR5 memory per socket across 12 memory channels at speeds up to 6400 MT/s. In a dual-processor server configuration, total system memory capacity can reach up to 6TB.

Q: What PCIe generation does the AMD EPYC 9455 support?
A: The EPYC 9455 supports PCIe 5.0 with 128 lanes per socket, providing high-bandwidth connectivity for NVMe SSDs, GPU accelerators, and high-speed networking adapters.

Q: Is this processor suitable for virtualisation and HPC workloads?
A: Yes. With 48 cores, 96 threads, 256 MB L3 cache, and 576 GB/s memory bandwidth per socket, the EPYC 9455 is well-suited to virtualisation (VMware, Hyper-V), large relational databases, analytics, and high-performance computing environments.

Q: Can I purchase the HPE P72654-B21 in Australia from IP Trading?
A: Yes. iptrading.com.au is an Australian B2B IT hardware specialist stocking HPE server processors including the P72654-B21. Contact the team for availability, volume pricing, and compatibility advice tailored to your HPE ProLiant environment.
