Dual-CPU Dedicated Servers — Maximum Compute per Box

Dual-CPU isn't always the right answer. Single 64-core EPYC 7763 has more cores than dual 32-core EPYC 7543 and avoids NUMA latency. But for these workloads, dual-socket is right:

• Memory bandwidth-bound: Each socket has its own DDR5 channels. Dual-socket = 2x memory bandwidth. Critical for in-memory databases (Redis, Aerospike), analytical workloads (ClickHouse, DuckDB at scale), and ML inference batch processing.
• RAM capacity > 256 GB: Single-socket platforms top out at 256-512 GB DIMMs depending on board. Dual-socket reliably hits 1 TB+. Required for large in-memory caches, JVM heaps over 200 GB, or running 50+ medium VMs.
• Multi-tenant isolation: Pinning tenants to NUMA nodes (one socket per tenant group) gives hard CPU + memory isolation. Useful for managed hosting providers reselling.
• Concurrent IO + compute: Heavy IO workloads benefit from one CPU handling NIC interrupts and IO while the other does compute. Particularly true for storage-heavy databases.

Current standard configurations, all with hardware RAID 10 NVMe, 25 Gbps unmetered networking, IPMI 2.0, and offshore DMCA-resistant hosting:

• Dual EPYC 7543 (Milan) — $199/mo: 2x 32-core (64c/128t total), 256 GB DDR4 ECC, 4x 4 TB NVMe RAID 10. Sweet spot for general-purpose virtualization and multi-tenant DBs.
• Dual EPYC 9354P (Genoa) — $349/mo: 2x 32-core (64c/128t), 384 GB DDR5 ECC, 6x 7.68 TB NVMe RAID 10. DDR5 + PCIe 5 lift IO ceiling 30-50% over Milan. Recommended for new ML workloads.
• Dual Xeon Platinum 8480+ (Sapphire Rapids) — $449/mo: 2x 56-core (112c/224t), 512 GB DDR5 ECC, 8x 7.68 TB NVMe RAID 10, 100 Gbps. Top-tier for HPC, pharma simulation, large model serving.

Custom configurations available — different RAM/disk capacities, GPU additions (NVIDIA L40S, A100), specific NIC requirements (Mellanox CX-6 for RDMA). Lead time for custom builds is 5-10 business days.

NUMA (Non-Uniform Memory Access) means each CPU socket has its own attached RAM. Accessing 'local' RAM (same socket) is fast; accessing 'remote' RAM (the other socket's DIMMs) goes over the inter-socket link and adds 50-100% latency.

Workloads that don't know about NUMA can run 20-40% slower on a dual-socket box than on a single-socket box with similar specs. The fix is NUMA-aware scheduling:

• Linux kernel auto-balancing: Reasonable defaults. 'numactl --hardware' shows your topology.
• Per-process pinning: 'numactl --cpunodebind=0 --membind=0 ./your-app' pins to socket 0. Useful for performance-sensitive single-process workloads.
• Hypervisor NUMA pinning: Proxmox, ESXi, KVM all support pinning VMs to a single NUMA node. Recommended when VMs are smaller than a socket.
• DB engine awareness: Postgres has NUMA pinning options. ClickHouse, Aerospike, ScyllaDB are NUMA-aware out of the box.

We document NUMA topology in your customer panel so you don't have to guess.

All dual-CPU plans include:

• 25 Gbps unmetered network: Two 10 Gbps + one 5 Gbps NIC, or two 25 Gbps depending on chassis. Bonded by default for failover.
• ECC RAM: Single-bit error correction, double-bit detection. Required for multi-day uptime at high density.
• Dual PSUs: Both connected, A/B power feeds in the data center.
• RAID 10 storage: Survives one drive failure per mirror. RAID controller cache battery-backed.
• IPMI 2.0: Full out-of-band management.

Provisioning time after payment confirmation: 24-48 hours for stocked configurations (Dual EPYC 7543), 5-10 business days for custom builds. Bitcoin, Monero, USDT-TRC20, and bank wire accepted.
