Compute shaders, which can draw points faster than the native rendering pipeline. Although I have to admit that WebGPU implements things so poorly and restrictive, that this benefit ends up being fairly small. Storage buffers, which come along with compute shaders, are still fantastic from a dev convenience point of view since it allows implementing vertex pulling, which is much nicer to work with than vertex buffers.

For gaussian splatting, WebGPU is great since it allows implementing sorting via compute shaders. WebGL-based implementations sort on the CPU, which means "correct" front-to-back blending lags behind for a few frames.

But yeah, when you ask like that, it would have been much better if they had simply added compute shaders to WebGL, because other than that there really is no point in WebGPU.
