GPU vs CPU Rendering
Cluster focuses on debates about using GPU versus CPU for UI, text, and browser rendering, including performance, hardware acceleration, energy efficiency, and modern frameworks like WebRender and Chromium.

It's CPU rendering, GPU is on the roadmap
All of it that shows rendering beyond what GPUs "only know".
Depends how complex your video game is.It has a GPU back end so it can be pretty fast, but it is still focused on very high quality antialiased rendering so it isn't crazy fast. Apps like Chrome and Sublime don't repaint the entire screen every frame or when scrolling, only the parts that change, so they can afford high quality.
yes but is the rendering performed in GPU, or in software is the question
This seems to be mostly for rendering not GPGPU.
Nearly all text rendering libraries I've checked uses the GPU.
gpu does a favor to this kind of rendering?
Browsers largely make use of the GPU for UI rendering. Direct2D, Cocoa, QT and GTK(4) are all hardware accelerated as well. So not really sure what you mean?
CPU rendering should not be a thing in 2021
Chromium (and Firefox) do GPU accelerated raster as well as composition. That page you linked is about a very specific case of wanting to get the pixels back to reuse in a different context. In that situation doing the work on the GPU and then copying back to the CPU may be slower than keeping it on the CPU the whole time.
