WebGPU 'core-features-and-limits'

The 'core-features-and-limits' feature signifies a WebGPU adapter and device support the core features and limits of the spec.

concepts

  1. Core Features

    WebGPU baseline guaranteed across conforming adapters. Cleaner programming model for the common path.

  2. Compat-mode comparison

    Request two devices — default vs. requiredFeatures: ["core-features-and-limits"] — and compare features & limits side by side. Show the gate library code can rely on.

  3. Limit Shopper

    Pick a workload preset (huge textures / huge compute / many storage buffers), translate into requiredLimits, request a device, and read back which limits were actually honoured against the core baseline.

  4. Feature Matrix

    Every optional WebGPU feature flag (BC, ETC2, ASTC, shader-f16, timestamp-query, dual-source-blending…) against the v136 core baseline, your adapter, and your device. Shows exactly what's portable.

why it shipped

At this stage the spec requires that all WebGPU implementations report this feature.
