What ScoreBench measures
- Processor, one core: five workloads written in plain JavaScript (integers, floating point, sorting 60,000 numbers, hashing and reading 32 MB of memory) run on a single core. This is what makes apps and web pages feel quick.
- Processor, all cores: the same workloads shared between as many threads as help. The browser may round the core count, so ScoreBench tries more threads and keeps the number after which speed stops growing.
- Graphics: the GPU draws four scenes at 1280×720 off screen, each loading a different part of it: glowing particles (arithmetic), texture sampling, stacked translucent layers (fill rate and blending) and a grid of 129,000 small triangles (geometry).
These are the same tests, version 3, as in the Processor and Graphics sections of SmartBench, so the scores of the two tools can be compared directly.
How to run it
- Open ScoreBench and press Start. The run takes about 30 seconds.
- Keep the tab in front and the screen on. If the tab is hidden or the screen turns off, the browser slows the page down, so the run stops and nothing is saved.
- Watch the ring: first the processor on one core, then on all cores, then a small preview of the graphics scenes. Stop cancels the run.
- When it finishes, the scores and every subtest appear, and the result is added to Your previous runs.
If WebGL is unavailable, only the processor is tested. If the graphics driver resets during the run, the processor scores are still kept.
How to read the scores
- 1000 points is one performance core of a laptop with an Intel Core i5-12450H for the processor, and its built-in Intel UHD Graphics for the GPU. Twice as many points means twice as fast.
- All cores grows with the number of cores; the line under it shows how many times faster it is than one core and how many threads were used.
- ±% is how much the three measurements of each part differed. A few per cent is normal; more means something else was busy.
- Each score is a geometric mean of its subtests, so one unusually fast part cannot carry the total. The bars show which parts are stronger.
Scores depend on the browser engine as well as on the hardware. Compare devices in the same engine: Chrome with Chrome, Safari with Safari. Every browser on iPhone and iPad uses WebKit.
Frequently asked questions
Why is my score different every time?
Phones raise and lower their clock speed with temperature and battery level, and background apps take their share. Plug in the charger, close heavy apps, let the device cool down and run the test two or three times.
Can I compare my phone with a computer?
Yes, as long as both use the same browser engine. The scale is the same for every device.
Why is the graphics score low on my gaming laptop?
The browser may be using the built-in graphics instead of the discrete card. In Windows, set the browser to “High performance” in the graphics settings, or plug the laptop in.
Does the test send anything to a server?
No. The tests run in your browser; fof.lol only serves the page. The result leaves the device only if you share the link or a file yourself.
Is ScoreBench the same as AnTuTu or Geekbench?
No. Those are native apps with their own scales. ScoreBench measures what a browser can do, needs no install and is comparable only with itself and SmartBench.
