[Topic]: Comparison of WebGPU performance in different operating systems about orillusion HOT 1 OPEN

For the last two renderBundle test, please try without keep writing transformationMatrix.
Becase the writeBuffer got much worse performance in intel Macs. So for a same big number matrix, the mac end up with a much slower result.

If try the test without writeBuffer, only test executeBundles perofmacne, I belive you will get a very closed result.

by the way, the M1/2 Macs got much better writeBuffer performance due to its unified memory

But after all, the writeBuffer in WebGPU has some performance issues compared to bufferSubData in WebGL
You can try a live demo in https://codepen.io/ShuangLiu/pen/YzEEmLa to check the difference

Chromium also addressed some disccustions about writeBuffer:
