Description

The AMD EPYC 9684X server processor delivers 96 cores and 192 threads at 2.55GHz base (up to 3.70GHz boost), purpose-built for HPE ProLiant Gen11 servers tackling the most demanding HPC, cloud, and high VM-density workloads. Its defining advantage is an enormous 1152MB L3 cache — enabled by AMD 3D V-Cache technology — making it the go-to choice for cache-sensitive simulations, analytics, and computational workloads that benefit from keeping massive datasets close to the core.

Built on a 5nm process node with a Socket SP5 interface, the EPYC 9684X supports up to 3TB of DDR5 memory per processor across 12 channels at 4800 MT/s, and PCIe Gen 5 I/O for next-generation storage and networking throughput. AMD Secure Processor and HPE Silicon Root of Trust integration provide layered firmware security for enterprise deployments. Compatible with HPE ProLiant DL345, DL365, DL385, and DL395 Gen11 platforms. Order now at iptrading.com.au — trusted by Australian IT professionals.

FAQs

Q: Which HPE ProLiant servers are compatible with the P63493-B21 EPYC 9684X processor?
A: The AMD EPYC 9684X (P63493-B21) is compatible with HPE ProLiant Gen11 servers using the Socket SP5 platform, including the DL345, DL365, DL385, and DL395 Gen11. Always verify compatibility against HPE's QuickSpecs for your specific server model before ordering.

Q: What makes the EPYC 9684X different from other EPYC 9004 Series processors?
A: The EPYC 9684X features AMD 3D V-Cache technology, which stacks additional cache on top of the die to deliver a massive 1152MB L3 cache — far beyond standard EPYC 9004 processors. This makes it uniquely suited for cache-sensitive workloads such as HPC simulations, finite element analysis, and computational fluid dynamics.

Q: Can two EPYC 9684X processors be installed in one server for dual-socket configurations?
A: Yes. The EPYC 9684X supports dual-processor configurations via AMD's 3xGMI interconnect, enabling servers to scale to 192 cores and 384 threads in a single system, with up to 6TB of combined DDR5 memory.

Q: What memory type and capacity does the EPYC 9684X support?
A: Each EPYC 9684X processor supports up to 3TB of DDR5 memory across 12 memory channels at speeds up to 4800 MT/s (1DPC). In dual-socket configurations, total system memory capacity can reach 6TB.

Q: Does the EPYC 9684X include security features suitable for enterprise deployments?
A: Yes. The processor integrates AMD Secure Processor for platform-level security, and when paired with compatible HPE ProLiant Gen11 servers, benefits from HPE Silicon Root of Trust, which validates firmware integrity from power-on to prevent tampering or malicious code injection.

Q: Can I purchase the HPE P63493-B21 EPYC 9684X processor in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is a trusted Australian B2B IT hardware reseller supplying HPE server processor options including the P63493-B21. Contact us for pricing, availability, and volume procurement support tailored to Australian businesses.
