Benchmarking AMD EPYC 9004 vs Intel Xeon on Modern Cloud VPS Workloads
We ran 10,000 synthetic and real-world Geekbench, Sysbench, and PostgreSQL pgbench tests across our Gen4 EPYC and Xeon fleets. Here are the raw numbers.
Introduction & Testing Methodology
When engineering the NodexVPS cloud hypervisors, our primary goal was to maximize per-thread instruction throughput while eliminating micro-architectural jitter under multi-tenant load. In this deep benchmark, we pit the AMD EPYC 9004 "Genoa" against Intel Xeon 4th Gen "Sapphire Rapids" across identical RAM and PCIe Gen4 NVMe configurations.
All virtual machines were configured with 4 vCPUs, 8 GB DDR5 ECC RAM, and tested over a continuous 72-hour sustained burn-in period.
1. Geekbench 6 Single-Core & Multi-Core Performance
Single-core performance directly dictates how fast dynamically interpreted languages (Node.js, Ruby, Python, PHP) process web requests:
- AMD EPYC 9004 vCPU: Single-Core 2,180 | Multi-Core 7,940 - Intel Xeon 4th Gen vCPU: Single-Core 1,890 | Multi-Core 6,820
The Zen 4 5nm compute dies with massive 32MB L3 cache slices provide an immediate ~15.3% single-thread execution advantage.
2. Database Transactions Per Second (PostgreSQL pgbench)
We executed an intensive 50-client OLTP workload with 100,000 transactions over a 20GB dataset fitting inside disk buffer cache:
- AMD EPYC + Samsung PM9A3 NVMe: 14,280 TPS with 3.4ms p99 latency - Standard Cloud Competitor SSD: 4,120 TPS with 28.6ms p99 latency
Enterprise PCIe Gen4 direct hardware pass-through guarantees that database flush operations do not queue up behind hypervisor abstraction layers.
Conclusion
For compute-dense microservices, container builds, and database query throughput, AMD EPYC 9004 architecture represents the definitive cloud value leader. All NodexVPS Cloud VPS nodes are actively provisioned on these modern platforms.
