NBench review
A free, focused benchmark for Linux users comparing core system performance.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NBench is a free Linux/Unix port of release 2 of BYTE Magazine’s BYTEmark benchmark program. Its native-mode tests measure CPU, floating-point, and memory-system performance, making it a focused option for Linux users who want to compare those areas rather than run a broad suite of benchmark workloads. It is also suited to technically comfortable individuals: the package includes source code and documentation, alongside a Linux ELF binary.
The comparison feature gives results historical context: NBench compares them against two benchmark systems. The vendor’s page says a run takes less than 10 minutes on most machines, and users can submit results to the maintainer for posting. Those features offer a way to relate an individual run to historical baselines and submitted results, though the available comparison focus remains limited to the two named historical systems. Choose NBench when CPU, floating-point, and memory measurements are the specific goal; it is a less natural fit for buyers seeking customizable test profiles or a wider workload mix.
NBench is free, and the listed binary is for Linux. The source is described as having been compiled on SunOS, DEC Unix 4.0, DEC OSF1, HP-UX, DEC Ultrix, and MS-DOS, so users of those systems should expect to compile rather than rely on an included platform binary. The maintainer’s page was last updated January 2, 2017, a relevant consideration for anyone weighing project recency. Linux users seeking a straightforward historical comparison can consider it; those prioritizing a broader platform package or more varied benchmarking scope should look elsewhere.
