stress-ng vs UNIGINE Heaven Benchmark

stress-ng is a free utility for loading computer subsystems and operating system kernel interfaces with stress tests. Its project lists more than 390 tests, including suites for CPU, virtual memory, filesystems, and memory or CPU caches. CPU tests exercise floating-point, integer, bit-manipulation, and control-flow operations. Listed architecture coverage includes ARM, x86-64, RISC-V, MIPS, Power, SPARC, and s390x. The project originally aimed to reveal hardware problems such as thermal overruns and operating system bugs under heavy load. stress-ng can report test throughput to help observe performance changes between operating system releases or hardware types, but the project says it is not a precise benchmark suite. Some tests may heat poorly designed hardware or create excessive system thrashing that is hard to stop. On Linux, running as root adjusts out-of-memory settings so stressors can become unkillable in low-memory conditions; the README advises careful use. The project documents Docker snapshots and installation on recent Ubuntu releases through its PPA. It is licensed under GPL-2.0 and costs nothing.

UNIGINE Heaven Benchmark evaluates graphics hardware for GPU performance, stress stability and cooling-system load. It runs on Windows, Linux and macOS, supports custom test profiles, and provides a comparison database for results. Output can be exported as HTML; CSV export is listed for Advanced and Professional plans. Command-line use and automation are supported. The Basic plan is a free download. Advanced costs $14.95 a month for one seat, Professional costs $495 a month for one seat, and Enterprise costs $7,500 a month for unlimited seats. The benchmark is offered by UNIGINE Heaven Benchmark, which is listed as founded in 2005 and headquartered in Abu Dhabi, UAE. Its workload areas focus on graphics processing, stability under sustained stress and cooling behavior. The operating-system coverage lets users run the benchmark across three desktop platforms, while custom profiles allow test settings to be tailored. Paid plans define seat quantities, and CSV export is restricted to the two higher listed paid tiers.
