Don't know how useful this info is, but I just went from 7/22 Pluto CHT to 7/29 Pluto No CHT, then added CHT to it. I ran OpenGL benchmarks along the way, here are the numbers:

--------------------------------
7-22 pluto CHT
alpha texture (128x256 rgba)
20651 kPixels/s

torus (3k triangles) one light
7024 kPixels/s

color blending
19966 kPixels/s

sub texture (128x128 15x15)
12365 kPixels/s

--------------------------------
7-29 Pluto no CHT, right after flash
alpha texture (128x256 rgba)
19875 kPixels/s

torus (3k triangles) one light
8718 kPixels/s

color blending
19874 kPixels/s

sub texture (128x128 15x15)
11792 kPixels/s

--------------------------------
7-29 Pluto no CHT, CHT installed by user,
all apps installed.

alpha texture (128x256 rgba)
20114 kPixels/s

torus (3k triangles) one light
8663 kPixels/s

color blending
20845 kPixels/s

sub texture (128x128 15x15)
12071 kPixels/s


I'm assuming any small variations are just noise, but you can see about a 20% improvement in the torus numbers with the new build.

I can't tell if this actually translates into a snappier user interface or not. As usual, the phone has to break in for a bit after a reset. Initially it's pretty clunky, then in a few minutes it becomes much snappier. Regardless, looks like another winner.
