Prime95 vs UNIGINE Heaven Benchmark

Prime95 is free Mersenne-prime search software for people who want to contribute computing work to GIMPS. It can also put a sustained workload across CPU cores to check processor and L1, L2, and L3 cache stability. For project tasks, Prime95 contacts PrimeNet for work; users can monitor computer progress and manage assignments remotely through the account’s CPUs page. Listed work includes PRP and Lucas-Lehmer tests, P-1 and ECM factoring, and trial factoring. Downloads include Windows, Linux, Mac OS X command-line, and FreeBSD builds. Administrators can choose a GUI-less Windows service build, which is intended for Windows Server experts. The source archive covers Windows, Linux, FreeBSD, and Mac OS X, though the code is described as non-portable. Version 30.3 introduced a dialog for limiting resource use. GIMPS participation is free and open internationally. The license permits indefinite free use on computers users own or are authorized to use, and provides the software as-is without warranty.

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.
