Description

84-core, high-density compute engine for massively parallel, memory- and I/O-intensive workloads. Based on EPYC 9004 (Zen 4, 5nm) with SP5, it scales memory bandwidth via 12-channel DDR5 and accelerates I/O with PCIe 5.0. Ideal for large virtualization clusters, analytics, and cloud-native services. Multi-socket capable for even higher core counts per node.

Features

Extreme core density for consolidation and parallel workloads
- 12-channel DDR5 for high memory bandwidth per socket
- PCIe 5.0 and CXL for next-generation accelerator and storage I/O
- Scales to 2-socket platforms for maximum core counts
- Robust security feature set for virtualized and multi-tenant environments

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.
