SciChart founder here, we've added ChartGPU vs. SciChart to our performance test suite - it holds up pretty well, but SciChart still about an order of magnitude faster

Innovation like this is fantastic btw and is good for the community! WebGPU is an awesome technology. So, this not only pushes us to be better but also consider how to add value to customers/users
