# AMD Ryzen 9 5950X vs 9950X: the CPUs inside Tihost VPS

> **In short:** Every Tihost VPS runs on a 16-core AMD Ryzen 9: the Ryzen 9 5950X (Zen 3, up to 4.9 GHz, DDR4) in Germany and Finland and the Ryzen 9 9950X (Zen 5, up to 5.7 GHz, DDR5, AVX-512) in Poland. The 9950X is faster per core and much stronger at vector workloads; the 5950X is cheaper for the same vCPU and memory.

**Key takeaways:**

- Tihost VPS in Germany and Finland run on the AMD Ryzen 9 5950X (Zen 3, up to 4.9 GHz, DDR4), and in Poland on the AMD Ryzen 9 9950X (Zen 5, up to 5.7 GHz, DDR5).
- The AMD Ryzen 9 5950X and Ryzen 9 9950X each have 16 cores, 32 threads and 64 MB of L3 cache; the CPUs differ in architecture generation, clock speed, memory type and instruction set.
- According to AMD, Zen 4 brought about 13% higher IPC than Zen 3 and Zen 5 about 16% more than Zen 4, so the Ryzen 9 9950X is noticeably faster per core than the Ryzen 9 5950X.
- The Ryzen 9 9950X supports AVX-512 with a 512-bit datapath, while the Ryzen 9 5950X tops out at AVX2; the `lscpu` command shows which instructions are visible inside a VPS.
- Desktop Ryzen 9 chips boosting to 4.9-5.7 GHz are usually faster than server EPYC and Xeon CPUs on single-threaded VPS work - web requests, game ticks and database queries.

## CPU specifications

|  | AMD Ryzen 9 5950X | AMD Ryzen 9 9950X |
| --- | --- | --- |
| Architecture | Zen 3 | Zen 5 |
| Cores / threads | 16 / 32 | 16 / 32 |
| Base clock | 3.4 GHz | 4.3 GHz |
| Boost clock | 4.9 GHz | 5.7 GHz |
| L3 cache | 64 MB | 64 MB |
| TDP | 105 W | 170 W |
| Process | 7 nm | 4 nm |
| Memory | DDR4 | DDR5 |
| PCIe | PCIe 4.0 | PCIe 5.0 |
| Released | 2020-11 | 2024-08 |
| Used in | Germany, Finland | Poland |

Both CPUs have 16 cores, 32 threads and 64 MB of L3 cache. The difference is the architecture generation - Zen 3 (2020) versus Zen 5 (2024) - and with it the clocks, the memory type and the instruction set.

## Why Ryzen and not a server EPYC or Xeon

Server CPUs win on core count - 64 cores and more - but each core runs at a lower clock. Desktop Ryzen 9 chips boost to 4.9-5.7 GHz, and for most VPS workloads that matters more: a web request in PHP, Node.js or Python, a game tick or the single-threaded part of a database runs on one core, and its speed is set by clock and IPC. That is why a Ryzen server with the same vCPU count usually responds faster.

## What a vCPU means at Tihost

A vCPU is one host CPU thread assigned to the virtual machine by the KVM hypervisor. A 4 vCPU plan means your OS sees four processors and can run four threads in parallel on Ryzen 9 cores. Virtualization is full (KVM), so the server runs its own OS kernel, just like a physical machine.

## How the 9950X beats the 5950X in practice

- **Faster single core.** According to AMD, Zen 4 brought about 13% higher IPC than Zen 3, and Zen 5 about 16% more than Zen 4; on top of that, peak clock rose from 4.9 to 5.7 GHz.
- **DDR5 memory** instead of DDR4 - more bandwidth, which shows in databases, caches and analytics.
- **Full AVX-512** with a 512-bit datapath - speeds up compression, encryption, media encoding, scientific code and CPU inference. Run `lscpu` to see which instructions are exposed inside your virtual machine.
- **Up to 10 Gbps** at the Polish site where the 9950X runs, versus 1 Gbps in Germany and Finland.

## Which site to pick for your workload

| Workload | CPU | Location |
| --- | --- | --- |
| VPNs, bots, landing pages, small websites | Ryzen 9 5950X | Germany or Finland - cheaper |
| Online stores, CRMs, Docker stacks | Ryzen 9 5950X | Germany or Finland |
| Game servers, high-frequency APIs | Ryzen 9 9950X | Poland |
| Video encoding, compression, CPU ML inference | Ryzen 9 9950X | Poland |
| File distribution, heavy outbound traffic | Ryzen 9 9950X | Poland - up to 10 Gbps |

## FAQ

### Which CPU do Tihost VPS use?

Tihost VPS run on the AMD Ryzen 9 5950X in Germany and Finland and the AMD Ryzen 9 9950X in Poland. Both have 16 cores / 32 threads.

### Which is faster for a VPS: Ryzen 9 5950X or 9950X?

The Ryzen 9 9950X is faster: newer architecture (Zen 5 vs Zen 3), higher clock (up to 5.7 vs 4.9 GHz), DDR5 memory and AVX-512 support. The 5950X is cheaper for the same configuration.

### Do Tihost VPS support AVX-512?

The Ryzen 9 9950X at the Polish site has AVX-512; the Ryzen 9 5950X (Germany, Finland) tops out at AVX2. Run lscpu to see which instructions are exposed inside your server, and if your workload needs a specific set, check with support before ordering.

### What is a vCPU?

A vCPU is one host CPU thread assigned to your virtual machine by the KVM hypervisor. 4 vCPU means four processors visible to the server's OS.

### How do I check CPU performance on a VPS?

The `lscpu` command shows the CPU model and available instructions on a VPS, while real CPU, disk and network speed is measured with benchmarks - the procedure is in the [VPS benchmark guide](https://tihost.io/en/blog/vps-benchmark).
