The AMD SP5 socket houses 160 cores and 320 threads in the EPYC 9845 processor, a fifth-generation data centre CPU built on the Zen 5 architecture and manufactured at TSMC's 3nm process node. This processor carries the part number 100-000001315 and delivers maximum boost frequencies of 3.7 GHz across a thermal design power envelope that fits seamlessly into OCP and air-cooled server platforms. The EPYC 9845 targets high-density compute environments where per-socket thread count directly influences return on infrastructure investment—whether you are architecting a new data centre, expanding an AI training cluster, or consolidating virtualized workloads across a smaller physical footprint.

AMD EPYC processors in the 9005 series have established themselves as the backbone of enterprises that require both raw compute density and per-thread efficiency. The 9845 processor sits at the top of the lineup, making it the natural choice for infrastructure teams that have already committed to the SP5 ecosystem and need maximum parallelism without moving to a different socket. With 512 MB of L3 cache and support for up to 8 DDR5 memory channels per socket operating at 6400 MT/s, memory-bound workloads benefit from both capacity and bandwidth that scale predictably with the core count. The processor supports both single-socket and dual-socket configurations, allowing architects to right-size deployments from 160-core single-socket designs all the way to 320-core systems that maintain coherent access patterns across a shared memory fabric.

PCIe 5.0 connectivity is a defining feature of the EPYC 9845 processor. Each processor provides 128 PCIe 5.0 lanes that can be configured as x16, x8, x4, or x1 form factors, enabling direct attachment of high-bandwidth storage controllers, network interface cards, and accelerator modules without the bandwidth compression that plagued earlier generations. For storage architects evaluating NVMe flash arrays or network engineers building 400G fabric spines, this lane count removes a historical bottleneck. The part number 100-000001315 ships with AMD Infinity Guard security features including SEV-SNP, SME, TSME, and PSP—a requirement for any regulated workload or multi-tenant cloud deployment where memory encryption must operate at line rate without measurable performance tax.

Virtualization support on the AMD EPYC platform includes AMD-V for traditional hypervisor deployments, AMD SEV for encrypted guest memory, and AMD SEV-ES and SEV-SNP for environments where the host itself cannot be trusted with guest execution context. This layered approach to security means the EPYC 9845 fits equally well in public cloud infrastructure, private data centres with strict compliance boundaries, and hybrid deployments where workloads migrate between environments. System administrators and infrastructure teams responsible for security posture find the hardware-enforced encryption transparent to the application layer while measurably reducing the attack surface of shared infrastructure.

Omnixon Global stocks the EPYC 9845 (part number 100-000001315) as part of our core AMD EPYC processor lineup serving data centres, colocation facilities, and enterprise AI labs across the UAE, GCC region, and beyond. We understand the qualification cycles, lead times, and compatibility requirements that govern processor procurement in the region.
