How Many Cores Does the OpenMetal XL v5 Have

Q: How many cores does the OpenMetal XL v5 have?

The OpenMetal XL v5 provides 64 physical cores and 128 threads, delivered as two Intel Xeon 6530P processors with 32 cores per socket on the Granite Rapids architecture.

The 6530P is a P-core SKU from Intel’s Xeon 6 Granite Rapids family, fabricated on the Intel 3 process node. Each socket runs at a 2.3 GHz base clock with a 4.1 GHz max turbo. The cores are dedicated to a single tenant — there is no hypervisor, no vCPU oversubscription, and no shared-CPU steal. Hyperthreading is on by default to expose 128 threads, but customers with hyperthread-averse workloads (HFT, real-time, certain HPC) can disable it from the BIOS via IPMI.

Granite Rapids brings AMX, AVX-512, AES-NI, and DL Boost on every core. These ISA extensions are available inside Intel TDX trust domains as well, which matters for confidential workloads that need vectorized math, in-CPU TLS acceleration, or INT8 inference without losing accelerator features to the TEE boundary. The full PCIe 5.0 lane budget (88 lanes per processor, 176 total) is exposed to the OS, feeding both the four NVMe data drives and the four 10 Gbps NICs without contention.

The 64-core / 128-thread count is unchanged from the XL v4 (which used the Xeon Gold 6530, also 32 cores per socket). What changed at v5 is the architecture (Granite Rapids vs Emerald Rapids), process node (Intel 3 vs Intel 7), and memory speed (DDR5-6400 vs DDR5-4800). For dense Proxmox / KVM virtualization, large PostgreSQL primaries, multi-tenant SaaS, and Kubernetes worker pools, the 64 dedicated physical cores plus 1 TB of fast DDR5 are the configuration that lets the server actually saturate its memory bandwidth — which was the bottleneck on the predecessor.
