I wanted to quickly compare how different Hetzner servers are doing (especially in single-threaded), for CPU-intensive tasks.
I ran sysbench on four different machines:
Hetzner Servers Tested
- Hetzner Cloud CPX21 (AMD EPYC Processor, 3vCPU, 4GB RAM) ~9EUR/mo
- Hetzner Dedicated EX44 (i5-13500, 64GB RAM) ~40EUR/mo
- Hetzner Server Auction (i7-8700 128GB RAM) ~40EUR/mo
- NEW: Hetzner Dedicated EX63 (Intel Ultra 7 265, 64GB RAM) ~69EUR/mo
Benchmark
Install
sudo apt-get install sysbench
Run
Each benchmark is run 3 times and the best result is taken.
sysbench cpu run
sysbench --threads="$(nproc)" cpu run
Results Summary
Results - Single Thread
| Server | Score (events/sec) |
|---|---|
| EX63 (Intel Ultra 7 265) | 4343.19 |
| EX44 (i5-13500) | 4133.64 |
| CPX21 (AMD EPYC) | 1617.52 |
| Server Auction (i7-8700) | 1480.96 |
Results - Multi-thread
| Server | Threads | Score (events/sec) |
|---|---|---|
| EX63 (Intel Ultra 7 265) | 20 | 119944.36 |
| EX44 (i5-13500) | 20 | 50234.72 |
| CPX21 (AMD EPYC) | 3 | 4835.93 |
| Server Auction (i7-8700) | 12 | 13043.05 |
Summary
EX63 (Intel Ultra 7 265) leads both single- and multi-thread performance. It scores about 5% higher than EX44 in single-thread and 2.4× higher in multi-thread.
EX44 (i5-13500) remains strong for its price, still delivering excellent per-core performance and roughly half the multi-thread throughput of EX63.
CPX21 (EPYC) and Server Auction (i7-8700) stay far behind in both metrics.
Conclusion
For CPU-bound workloads, EX63 provides top raw compute power, particularly if you can utilize all cores.
EX44 continues to offer the best price-performance balance.
The cloud CPX21 remains suitable for lightweight or bursty compute tasks.
