stress-ng vs y-cruncher
Both stand on pc stress testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

stress-ng offers extensive ways to load-test computer subsystems and operating system interfaces across many architectures. Its own cautions matter: some tests can strain hardware, and root use on Linux can make stressors difficult to stop when memory is low.

y-cruncher combines large calculations with benchmarking and stress testing, and supports Windows and Linux. Consider the Linux build tradeoffs, the project’s hiatus on major redesigns, and licensing terms for commercial use.

stress-ng: what it does well
- Lists more than 390 stress tests.
- Covers CPU, virtual memory, filesystems and caches.
- Lists support for ARM, x86-64, RISC-V and other architectures.
- Free to use under GPL-2.0.
What to know first
- Some tests can overheat poorly designed hardware.
- Heavy tests may cause difficult-to-stop system thrashing.
- Root use on Linux can make stressors unkillable under low memory.
- Not intended as a precise benchmark suite.
y-cruncher: what it does well
- Calculates constants to trillions of digits
- Separate computation and verification algorithms for most constants
- Supports SSE, AVX, and AVX512
- Manages swap space for large computations
- Can detect and correct minor errors
What to know first
- Static Linux build lacks TBB and NUMA binding
- Dynamic Linux build is less portable
- Commercial use requires contacting the developer
- Major algorithm redesigns and rewrites are on hiatus
