Reference estimate guide
Integrated GPU Volume Shader BM Guide
How to test Intel, AMD, and other integrated GPUs with Volume Shader BM without confusing memory bandwidth, power limits, and browser settings.
These notes describe reference ranges and testing conditions. They are not official vendor rankings and should not be mixed with live leaderboard submissions without matching the same preset, browser, and power mode.

Source label
Device pages clearly label conservative estimates separately from community samples.
Compare fairly
Keep browser, preset, power profile, render size, and thermal state fixed before comparing.
Integrated GPUs share power and memory bandwidth with the CPU, so Volume Shader BM results can change when background apps, video playback, or CPU-heavy tasks are active.
Start with Fog Sphere or Twirl Smoke before using Cloud Layer. If a laptop is unplugged, battery policy can reduce GPU clocks and make the same preset look much slower.
Reference estimates for integrated GPUs should be treated as broad ranges because OEM cooling and memory configuration can change sustained performance.
Comparison guidance
- Plug the laptop in before recording a comparison run.
- Use the same browser and disable battery saver or low-power modes.
- Prefer FPS trend and 1% low over one short burst number.
Common bottlenecks
Shared memory bandwidth
High-resolution canvas workloads can compete with the CPU and system memory.
Laptop power profile
Balanced and battery modes often reduce sustained GPU frequency.
Thermal headroom
Thin laptops may drop FPS during repeated or long shader runs.

Device class FAQ
Why do integrated GPU results vary so much?
Memory speed, cooling, laptop power mode, and CPU activity all affect the GPU because resources are shared.
Which preset should integrated GPUs start with?
Start with Fog Sphere, then Twirl Smoke or Cloud Layer if the browser remains smooth.
