The core finding is that WebGPU delivers 3–8× faster GEMM (matrix multiplication) execution at large matrix sizes (2048×2048+) due to native compute shaders, storage buffers, and workgroup shared memory — capabilities WebGL entirely lacks. Benchmarks were run across Apple M2, NVIDIA RTX 3060, and Intel UHD 630 hardware. For real-world LLM inference (Phi-3-mini on M2), token latency drops from ~320 ms to ~85 ms when switching from WebGL to WebGPU. The article includes full WGSL and GLSL shader code, a timing harness using GPUQuerySet timestamp queries, and practical guidance for implementing WebGPU-first backends with WebGL fallback. WebGL remains the necessary fallback for older hardware and Safari stable. ## Full article daily.dev links to this article rather than hosting it.
