Unleashing the GPU

WebGPU is not just an update; it's a paradigm shift. Unlike WebGL, which is based on OpenGL ES, WebGPU maps directly to modern APIs like Vulkan, Metal, and DirectX 12.

Chip Architecture

Compute Shaders

The biggest game-changer is Compute Shaders. We can now offload physics, AI, and fluid simulations entirely to the GPU without blocking the main thread.


rust
// WGSL Shader Example
@compute @workgroup_size(64)
fn main(@builtin(global_invocation_id) global_id : vec3<u32>) {
  // Parallel processing logic here
}

Performance Benchmark

I ran a particle simulation with 1 million entities.

WebGL 2.0: 15 FPS
WebGPU: 120 FPS
