The best UserBenchmark alternative depends on the job.

No single tool replaces UserBenchmark, because it does several jobs at once. GPU: 3DMark. CPU rendering: Cinebench. Cross-platform CPU: Geekbench. Whole system with storage: PassMark. Sustained-load behaviour and why it fell, with no install: SystemCheck.

Why people look for an alternative

• Its rankings have drawn public criticism. In July 2019 it changed the weights in its effective CPU speed index (ComputerBase reported single-core moving from 30 to 40 percent, quad-core from 60 to 58 and multi-core from 10 to 2), which lowered processors with many cores, including most of AMD's range, according to Wikipedia. That criticism concerns the ranking built on top of the measurements rather than the individual sub-scores.
• In April 2020 the moderators of r/hardware banned posts and links about it, r/Intel followed with a full ban and r/AMD restricted it, as reported by Notebookcheck.
• In 2024 it began charging $10 a year to run during periods of high use, with free testing slots otherwise.

The options, by the job each does best

Most of these are not SystemCheck, because for most of these jobs they are the better answer.

• 3DMark

  A native GPU benchmark suite from UL Solutions, for Windows, macOS, Android and iOS.

  Best for

  A GPU number you can defend in a review or a forum argument, and stress-test loops with temperature and clock charting.

  Limitation

  It is a paid product for the full feature set, GPU-focused rather than whole-system, and needs a real install.

• Cinebench

  A CPU and GPU benchmark from Maxon built on Redshift, Cinema 4D's default render engine, so the workload is real rendering rather than a synthetic proxy.

  Best for

  Comparing CPU multi-core rendering throughput against published results.

  Limitation

  It measures one kind of workload. A strong Cinebench score does not tell you much about gaming or mixed real-world use.

• Geekbench

  A cross-platform CPU and GPU-compute benchmark from Primate Labs that runs on Windows, macOS, Linux, Android and iOS.

  Best for

  Comparing across operating systems and device classes, including phones, on a common scale.

  Limitation

  Runs are short, so it characterises burst performance far better than sustained behaviour.

• PassMark PerformanceTest

  A native Windows suite whose standard tests cover CPU, 2D and 3D graphics, memory and disk.

  Best for

  A broad whole-system sweep in one pass, including storage and memory, which most single-purpose tools skip.

  Limitation

  Native install required, Windows only by its store listing, and the Advanced Test Suite is free for 30 days; the basic tests do not expire.

• SystemCheck

  This site

  A browser-based stress test. Four stages (a sustained multi-core CPU load, a memory bandwidth and latency stage, a GPU raster load and a path-tracing load) with no install and no account for the core test. It reads the shape of the CPU curve to name why performance fell: a power budget expiring, cooling falling behind, or something else contending for the cores.

  Best for

  Finding out whether a machine holds its performance under sustained load and, when it does not, why, on any desktop OS, without installing anything.

  Limitation

  It cannot read temperatures, power draw, fan speed or VRAM. No browser exposes an API for them. Results are directional rather than lab-grade and move with browser, driver and background load.

• HWiNFO or HWMonitor

  Hardware monitoring utilities, not benchmarks. They read sensors and log them over time.

  Best for

  Seeing actual temperatures, clocks, power draw and fan speeds, the data no browser-based tool can access.

  Limitation

  They produce no score and apply no load. Pair one with a benchmark rather than using it instead of one.

How to test your PC without UserBenchmark

1. 1Close what you do not needQuit games, launchers, video calls and large downloads, and plug a laptop in. Anything else working on the processor shows up in the result.
2. 2Start the free testOpen the benchmark in a desktop browser and press start. The standard run takes about 3 minutes across 4 stages: a sustained CPU load, memory, GPU raster and path tracing.Open the benchmark
3. 3Leave the tab in frontBrowsers slow down background tabs, so keep the test visible and do not use the machine until it finishes.
4. 4Read the curve, not just the scoreThe report shows whether each stage held its speed and, when the CPU fell away, the shape of the loss and what it is consistent with: a power limit, cooling falling behind, or something else competing for the cores.How each stage is measured
5. 5Add a native tool for what a browser cannot seeFor temperatures, clocks and fan speeds run HWiNFO or HWMonitor alongside, and for a citable GPU score or a storage test use 3DMark or PassMark PerformanceTest.

For a single part, the CPU stress test and GPU benchmark pages explain what each stage measures, the bottleneck test reads processor and graphics slowdown from the same run, and the PC performance test page covers the whole run.

When UserBenchmark is still the right choice

UserBenchmark is still a reasonable first look if you want CPU, GPU, memory and storage covered in a single run, and you treat the individual sub-scores as the output rather than the headline composite ranking.

Questions

What is the best UserBenchmark alternative?

It depends on the job, because UserBenchmark does several at once. For a free, no-install test of whether a PC holds its CPU, GPU and memory performance under sustained load, and why it slows down when it does not, SystemCheck in a browser tab. For a citable GPU score, 3DMark. For CPU rendering, Cinebench. For comparisons across operating systems and phones, Geekbench. For a whole Windows system including storage, PassMark PerformanceTest.

Is UserBenchmark accurate?

Its individual sub-scores are measurements of your machine, but its headline rankings are disputed. In July 2019 it changed the weights in its effective CPU speed index, cutting multi-core from 10 to 2 percent as ComputerBase reported, which lowered processors with many cores. Wikipedia notes it is known in enthusiast communities for results that disagree sharply with other sources. Compare sub-scores rather than the composite rank, and check a second source.

Why is UserBenchmark banned on Reddit?

In April 2020 the moderators of r/hardware banned posts and links about it, saying such threads had no value and generated drama, and r/Intel followed with a full ban while r/AMD restricted it, as reported by Notebookcheck. The criticism behind it concerns how parts are ranked against each other, including the 2019 change to the effective speed index.

Is UserBenchmark safe to run?

The most detailed independent look we could find is from January 2019, when Born's Tech and Windows World found no known malicious code in the Windows program (2 of 68 scanners flagged it as suspicious), but noted it was not digitally signed and sent results to the developer with no opt-out inside the tool. We have not tested a later version. A browser test such as SystemCheck installs nothing.

Is there a free UserBenchmark alternative that needs no download?

SystemCheck runs entirely in a browser with no install and no account for the core test. It covers CPU, memory and GPU under sustained load but not storage, and it cannot read hardware sensors, so it is a narrower tool rather than a like-for-like replacement. What it adds that UserBenchmark does not is a reason: the report classifies the shape of the CPU curve and names the likely cause of a slowdown.

What should I use instead of UserBenchmark on macOS or Linux?

Geekbench runs natively on both. Cinebench covers macOS. SystemCheck works in a browser on any desktop OS.
