This page is generated from resources/profiles/dispersion/gpu_identity.json and resources/profiles/catalogue.json by scripts/generate-docs-reference.py. A GPU family is a set of WebGL and WebGPU values measured on real hardware. Every model in a family presents that family’s values, with its own vendor and renderer strings, which a page reads as UNMASKED_VENDOR_WEBGL and UNMASKED_RENDERER_WEBGL. A seed draws a family for the persona’s platform and then a model from the family. GPU explains how to choose one.
  • Share is the model’s weight as a share of its family: the fraction of seeds that draw the family and present this model.
  • Measured models were captured on a machine with that GPU. The other models are registered on the family, and present the family’s measured values with their own strings.
To pin a family, pass its id to --fingerprint-anchor. To pin a model, pass its renderer string to --fingerprint-gpu-renderer. A renderer string from another family is refused. Switches has both.

Windows, Intel, Direct3D 11

The family id is windows-d3d11-intel-79dfeb5b4f99. Windows personas on an x86 host draw from this family. It has 12 models. It was measured on Intel(R) UHD Graphics 630. Every model’s vendor string is Google Inc. (Intel).

Windows, NVIDIA, Direct3D 11

The family id is windows-d3d11-nvidia-0947761dfbe9. Windows personas on an x86 host draw from this family. It has 45 models. It was measured on NVIDIA GeForce RTX 3070 Ti and NVIDIA RTX A4500. Every model’s vendor string is Google Inc. (NVIDIA).

Windows, Qualcomm, Direct3D 11

The family id is windows-d3d11-qualcomm-6388f9914f3f. Windows personas on an ARM host draw from this family. It has 1 model. It was measured on Qualcomm(R) Adreno(TM) X2-90 GPU. Every model’s vendor string is Google Inc. (Qualcomm).

macOS, Apple, Metal

The family id is macos-metal-apple-850a91233555. macOS personas draw from this family. It has 12 models. It was measured on Apple M4 Max. Every model’s vendor string is Google Inc. (Apple).

Linux, NVIDIA, Vulkan

The family id is linux-vulkan-nvidia-adf287b8f0ee. Linux personas draw from this family. It has 11 models. It was measured on NVIDIA GeForce RTX 4070 Ti SUPER, NVIDIA GeForce RTX 4080 SUPER, NVIDIA GeForce RTX 3090 and NVIDIA RTX PRO 4000 Blackwell. Every model’s vendor string is Google Inc. (NVIDIA).

Linux, SwiftShader software renderer

The family id is linux-swiftshader-google-6922d61bab83. A seed never draws this family. Only --fingerprint-anchor selects it. It has 1 model. It was measured on SwiftShader Device (Subzero). Every model’s vendor string is Google Inc. (Google).
