ApexMark › GPU benchmark
GPU benchmark online
Test your graphics hardware in the browser with a visible WebGPU scene and a separate compute workload. ApexMark finds the highest resolution your device can sustain, verifies the work and combines both parts for a comparable GPU score.
Run the benchmarkA resolution ladder, not one fixed scene
One fixed resolution can be too heavy for a phone and too light for a powerful graphics card. ApexMark renders the same scene from 360p toward 4K, checks the images and records where the device stops sustaining 30 fps. That boundary sets its visual capacity index.
A separate verified WebGPU compute profile measures another kind of GPU work. The public ApexMark V1 graphics score requires both the visual ladder and the compute profile; a partial result is kept as evidence but is not ranked as a comparable GPU score.
Requirements
- A browser and device that expose WebGPU. Availability depends on the browser, operating system and graphics driver.
- A secure (HTTPS) page and hardware acceleration enabled.
- If WebGPU is unavailable, ApexMark reports it instead of inventing a GPU score.
Frequently asked questions
Can a browser test my GPU?
Yes, when WebGPU is available. ApexMark measures graphics and compute workloads as the browser runs them. That is useful for web performance comparisons, but not interchangeable with a native gaming benchmark.
Why does my GPU score say unsupported?
Your browser, operating system or graphics driver may not expose WebGPU. Update them, check hardware acceleration and try another compatible browser. Other available ApexMark tests can still run.
