I've been using this exact test for years now to judge a phone/tablet before buying/recommending - devices with the exact same SoC can differ wildly in performance.
Nowadays any phone that can't display 20k bunnies at 20FPS likely has:
1. An underpowered GPU.
2. Badly designed cooling.
3. A screen with a too high resolution.
Of course there are many more thorough and appropriate benchmarks, but this one doesn't require you to install anything and will give you an answer before you're approached by the store staff inquiring what is it that you're trying to do with the merchandise.
