Profiling GPU Rendering Walkthrough | Android Developers
The red section of the bar represents the time spent by Android's 2D renderer issuing commands to OpenGL to draw and redraw display lists. The height of this bar is directly proportional to the sum of the time it takes each display list to execute—more display lists equals a taller red bar. The orange section of the bar represents the time the CPU is waiting for the GPU to finish its work. If this bar gets tall, it means the app is doing too much work on the GPU. Note: While this tool is named Profile GPU Rendering, all monitored processes actually occur in the CPU.

There are a lot of speed test videos. But there are none with Profile GPU Rendering turned on, and showing real world performance.
For people, who dont know, this feature is easy way to show, if app is running smooth, or not (fps drops).
Are you interested in video comparisons with this feature on? If you could choose, would you rather have slightly faster app loading time, or smoother experience? Lets show reviewers that we care about this.
This post is inspired by people opinions, that google pixel is smoothest android phone, though speed tests deny it. And Profile GPU Rendering is the way to show this

Yes! Predictable performance at 60fps is much more noticeable than a 100ms difference in app opening times. Many "speedtest" videos are shot in 30fps and it's imposible to see janks and UI stutters from the video alone. With the GPU profiling, the bad performing phones would be much easier to spot.

GPU Profiling 101 – Nathan Reed’s coding blog
October 12, 2011 - While the GPU is rendering frame n, the CPU is forging ahead and working on frame n + 1. When the GPU finishes frame n, it puts it up on screen and starts on frame n + 1; then the CPU gets the go-ahead to start on frame n + 2. But this means that if we fire off a bunch of timestamp queries in frame n on the CPU, then wait for them to complete before we start the next frame, we’ll be serializing the system.

These lines are based on the device's vsync period (desired framerate), usually 16ms (60fps)
And represent a percentage of this period:
Green - 80%
Yellow - 100%
Red - 150%
so for 60fps they are
Green - ~13ms (~78fps)
Yellow - 16ms (60fps)
Red - 24ms (~41fps)
Source:

r/essential on Reddit: Profile GPU rendering

Hi guys. I know this has been mentioned many times in the past, and Essential has added an adjustable Touch Sensitivity option under Developer options. I'm on the latest Android P beta 3, and I can clearly see many dropped frames when touch scrolling in Gmail or swiping on the home screen to touch scroll in the Google app. You can clearly see this for yourself by going in Developer options and setting Profile GPU rendering to "On screen as bars". Is this due to the inferior digitizer Essential is using, or is this due to unoptimized software and / or drivers??? One way to help prevent all these dropped frames that some notice and some do not is to root the device and set GPU governor to cpufreq or performance. This was reported to Essential a long time ago and the problem is clearly still there no matter what you select for the Touch Sensitivity option. Is Essential finally going to address these touch scrolling frame drops in the future??? This is separate from the touch scrolling screen jitters, but obviously it doesn't help the situation. Please Essential look into this one day in the not so distant future!

Setting GPU governor to cpufreq or performance is ideal if you need 2 hours of screen on time. Those bars are because of rather mediocre kernel optimization. Only a few devices, like Pixel 2 or OP6 can keep render 90% of frames at 60fps(== all bars below line). But this requires insane amount of time, developers and money to achieve, and essential, obviously, do not have either of those.
