(Odd, where I am located both my default search engines immediately return as first result "Graphical User Interface - Wikipedia". Well, your location settings change the search engine results you get.)
Which "speed" are you referring to? If the Max Carta renders A2 pages using the Floyd-Steinberg, as it looks, the rendering speed remains 125ms (or 8fps, the official speed of A2 mode for e-ink screens) and the time cost to apply the algorithm is negligible - the whole page rendering of A2 on the Max Carta seems to take 125ms. I never measured it, I saw no need - it looks as fast as it should.
If you refer to page rendering - I am not informed of any mode faster than A2. As I wrote earlier (26 Oct), the "Floyd mode" of the Dasung looks 125ms, 8fps - I counted the devices's screen updates in the frames in the video posted by Skynet84.

I really cannot see how they can be compared: they do not do the same thing.
One (the second) rearranges values so that ██▇▆▅▄▃▂▁▁ is made to be ███▁█▁█▁▁▁ instead of █████▁▁▁▁▁ ,
the other one (the first) excludes that passing through London to reach Paris from Rome is a good idea. I do not know what Floyd-Warshall is doing there.

If it were A2, you should only see black dots and white dots. Skynet84's video, in the "Floyd mode" part, seen in detailed zoom in its highest resolution version, does not seem to only display black and white dots.
