Description

Dense 64-core Zen 4 server CPU optimized for single-socket platforms, targeting consolidation, analytics, and high-throughput workloads. Combines massive core density with 12-channel DDR5 bandwidth and abundant PCIe 5.0 connectivity for accelerators and NVMe fabrics. Built on 5nm with SEV-SNP and rich ISA extensions for compute acceleration. Ideal for 1P SP5 servers seeking maximum per-socket performance without the complexity of a second CPU.

Features

High-density 64-core performance in a streamlined 1P design
- 12-channel DDR5 for exceptional bandwidth and capacity
- PCIe 5.0 (128 lanes) to feed GPUs, FPGAs, DPUs, and NVMe arrays
- Hardware-enhanced security with SEV-SNP
- Zen 4 instruction support for modern compute acceleration

FAQs

Q: Can this CPU be used in a dual-socket system?
A: No. P-suffix models are optimized for single-socket (1P) platforms.

Q: What memory footprint can a 1P system achieve?
A: Up to 6 TB per socket is possible on platforms that support maximum RDIMM/LRDIMM capacities.

Q: Is PCIe 5.0 supported for accelerators and NVMe?
A: Yes. Up to 128 PCIe 5.0 lanes are available per socket, platform permitting.

Q: What security features are included?
A: SEV-SNP as part of AMD Infinity Guard enables memory encryption and isolation for confidential computing.

Q: What workloads benefit most?
A: Virtualization density, analytics, container platforms, object storage, and software-defined infrastructure that scale with cores and I/O.
