Hmm, interesting. I've just tested my quad-core A33-powered MID-756 / F900 cheap chinese tablet of which there are thousands on ebay, and despite being 1.3 GHz, the figures come out at:
Total time: 5.0694 secs
average time: 0.50694 secs.
That's nearly 10 times slower than my Huawei P9 Lite. I knew it wasn't that fast, but that is surprising.
