Hetzner Servers Benchmarks

13 hours ago 1

I wanted to quickly compare how different Hetzner servers are doing (especially in single-threaded), for CPU-intensive tasks.

I ran sysbench on three different machines:

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

Benchmark

Install

sudo apt-get install sysbench

Run

Each benchmark is run 3 times and the best result is taken.

sysbench cpu runsysbench --threads="$(nproc)" cpu run

Conclusions

It seems like the EX44 has excellent value.

The EX44 server seems to have the best CPU performance, at a similar price with the older i7-8700 server. You might still want the auction server one if you need more RAM/storage (as it comes with 2x RAM and 2X storage for same price, but around 1/2 CPU performance).

The CPX21 server does reasonably well in single-core (matching an i7-8700), and it scales well on multicore (3x faster with 3 threads).

Going forward, I would likely focus more on the dedicated line with new AMD/Intel processors, as the single-core and multicore performance is drastically better than previous gen CPUs.
