Description

The HPE-certified AMD EPYC 9455P is a 5th Generation single-socket server processor delivering 48 cores and 96 threads at a 3.15 GHz base clock, boosting up to 4.4 GHz, with a 256 MB L3 cache and 300 W TDP. Built on the SP5 platform, it is engineered for HPE ProLiant Gen11 and Gen12 servers handling virtualisation, cloud, and data-intensive workloads where per-socket core density and memory bandwidth are critical.

Supporting 12 channels of DDR5 memory at speeds up to 6400 MT/s (on Gen12), up to 6 TB of addressable memory per socket, and PCIe 5.0 x128 I/O, the EPYC 9455P provides exceptional throughput for storage-heavy and compute-dense environments. Note: Heatsink Kit and Fan Kit are not included and must be ordered separately. Order now at iptrading.com.au — trusted by Australian IT professionals.

Features

- 5th Generation AMD EPYC architecture delivers improved performance per watt over prior generations
- Single-socket SP5 design with 48 cores and 96 threads — ideal for maximising density in 1P server configurations
- 12-channel DDR5 memory interface supporting up to 6400 MT/s on Gen12 platforms and up to 6 TB per socket
- PCIe Gen 5 x128 I/O enables high-speed NVMe storage and accelerator connectivity
- 256 MB L3 cache reduces memory latency for virtualisation, AI inference, and analytics workloads
- HPE-certified for seamless integration and firmware compatibility with ProLiant Gen11 and Gen12 platforms
- Supports bare metal, virtualised, and cloud-native deployment scenarios
- P-series (single-socket) designation — not compatible with multi-socket configurations

Warranty

Hewlett Packard Enterprise (HPE) offers a standard limited hardware warranty on its products, with coverage periods varying by product line. For instance, HPE ProLiant servers typically come with a 1 to 3-year limited warranty, while other products may have different durations.

FAQs

Q: Which HPE servers are compatible with the EPYC 9455P (P72664-B21)?
A: The EPYC 9455P is certified for HPE ProLiant Gen11 and Gen12 single-socket servers, including the HPE ProLiant DL345 Gen12 and DL365 Gen11. Always verify compatibility with HPE's QuickSpecs or the HPE Configurator before ordering.

Q: Does the P72664-B21 kit include a heatsink or fan?
A: No. The processor kit does not include a Heatsink Kit or Fan Kit. These must be ordered separately and are specific to the server chassis and thermal configuration you are deploying.

Q: What does the 'P-series' designation mean for the EPYC 9455P?
A: The 'P' suffix indicates this is a single-socket optimised processor. It does not support multi-socket configurations, making it suited for 1P server builds where single-node core density is the priority.

Q: How much memory can the EPYC 9455P support, and at what speed?
A: The EPYC 9455P supports up to 6 TB of DDR5 memory across 12 channels. On HPE ProLiant Gen11 platforms, speeds reach up to 6000 MT/s; on Gen12 platforms, speeds can reach up to 6400 MT/s, delivering up to 576 GB/s of memory bandwidth per socket.

Q: Can I purchase the HPE EPYC 9455P (P72664-B21) in Australia?
A: Yes. IP Trading (iptrading.com.au) supplies HPE server processors to Australian businesses, government, and IT professionals. Contact us for pricing, lead times, and volume enquiries.

Q: Is this processor suitable for virtualisation and cloud workloads?
A: Yes. With 48 cores, 96 threads, 256 MB L3 cache, PCIe 5.0 x128 I/O, and high-bandwidth DDR5 memory support, the EPYC 9455P is well suited for hypervisor-based virtualisation (VMware, Hyper-V, KVM), private cloud, and data-intensive enterprise applications.
