Not all VPS hardware is the same. The processor your VPS runs on directly affects performance. Understanding the difference helps you choose the right plan.
EPYC vs Ryzen Overview
| Feature | AMD EPYC | AMD Ryzen |
|---|---|---|
| Market | Server/datacenter | Desktop/workstation |
| Core count | Up to 192 (EPYC 9965, 9005 series); 96 on the EPYC 9654 in the table below | Up to 16 (Ryzen 9 9950X, 7950X3D, 5950X) |
| Memory channels | 12 on the 9004 and 9005 series | 2 |
| PCIe lanes | 128 | 24-28 |
| ECC memory | Yes | Depends on model |
| Single-thread speed | Good | Excellent |
| Multi-thread density | Excellent | Good |
| Price per core | Higher | Lower |
Which Matters for Your VPS?
Single-Thread Performance (Ryzen Wins)
Applications that primarily run on one thread:
| Workload | Single-Thread Importance |
|---|---|
| WordPress/PHP | Very high |
| Game servers (Minecraft, Rust) | Very high |
| Small Node.js apps | High |
| Database queries (simple) | High |
| Web serving (Nginx/Apache) | Medium |
Ryzen's higher clock speeds (up to 5.7 GHz boost on the 9950X and 7950X3D) usually make it faster per core than an EPYC, which trades clock speed for core count.
Multi-Thread Performance (EPYC Wins)
Applications that scale across many threads:
| Workload | Multi-Thread Importance |
|---|---|
| Video transcoding | Very high |
| Large database operations | High |
| Build/compile servers | High |
| Virtualization farm | Very high |
| Machine learning training | Very high |
EPYC's massive core counts and memory bandwidth handle these best.
What the Spec Sheets Say
These are AMD's own figures, for one common EPYC and the two Ryzen CPUs in our VPS plans:
| EPYC 9654 | Ryzen 9 9950X | Ryzen 9 3900X | |
|---|---|---|---|
| Cores / threads | 96 / 192 | 16 / 32 | 12 / 24 |
| Base / max boost | 2.4 / 3.7 GHz | 4.3 / 5.7 GHz | 3.8 / 4.6 GHz |
| L3 cache | 384 MB | 64 MB | 64 MB |
| Memory | DDR5-4800, 12 channels | DDR5, 2 channels (5600 MT/s with two modules) | DDR4, 2 channels, up to 3200 MT/s |
| Memory bandwidth | 460.8 GB/s per socket | 89.6 GB/s at DDR5-5600 | 51.2 GB/s at DDR4-3200 |
| Default TDP | 360 W | 170 W | 105 W |
The EPYC bandwidth figure is AMD's; the Ryzen figures are simple arithmetic (two 64-bit channels times the transfer rate). The pattern is the whole story: the EPYC has six times the cores of a 9950X and far more memory bandwidth, while the Ryzen boosts about 2 GHz higher. A single busy thread, like a Minecraft server's main loop or a PHP request, runs faster on the Ryzen. Hundreds of threads at once, like a busy database or a host full of VMs, favour the EPYC.
How much faster in practice depends on the workload, the generation you compare and how the provider has divided the machine. If it matters, benchmark your own application on both.
What to Choose
| Your Use Case | Best Hardware |
|---|---|
| Game servers | Ryzen (best single-thread) |
| WordPress/PHP sites | Ryzen |
| Small-medium VPS | Ryzen |
| Heavy database workloads | EPYC |
| Many containers/VMs | EPYC |
| Video processing | EPYC |
| General purpose | Either (Ryzen slightly better per core) |
NVMe SSD Storage
Processor matters, but so does storage:
| Storage Type | Random Read | Sequential Read |
|---|---|---|
| HDD | 100-200 IOPS | 100-200 MB/s |
| SATA SSD | 10,000-50,000 IOPS | 500 MB/s |
| NVMe SSD | 200,000-1,000,000 IOPS | 3,000-7,000 MB/s |
These are typical ranges, not guarantees; drives and RAID setups vary. NVMe removes storage as the bottleneck for most small workloads, which is why it matters as much as the CPU for databases and world loading.
Space-Node's VPS plans run on Ryzen, not EPYC: a Ryzen 9 3900X on Standard and a Ryzen 9 9950X on Premium, with NVMe storage in the Netherlands. Both tiers are out of stock until about the end of October.
