I'm not sure which Raspberry Pi, but assuming it's the latest one (this is the latest one, right?), here are its specs: https://www.raspberrypi.org/products/raspberry-pi-3-model-b/

Here are my phone's specs: http://www.gsmarena.com/apple_iphone_6s-7242.php

IMO they aren't super different. Sure, my phone runs at 1.84GHz while the Pi runs at 1.2GHz, but the Pi also has twice as many cores. My phone does have twice the Pi's RAM, but I don't think RAM is what made a difference here.

Here's the whitepaper

Yes, it's a Raspberry Pi 3.

No, it's not comparable to an iPhone 6s.

An iPhone 6s is about 5 times faster.

A Raspberry Pi 3 is about equivalent to a Samsung Galaxy S III (a five year old phone.)

You're totally right. Those geekbench scores are quite different! Scrolling and tabs with different information were still very fast on my iPod Touch (this was 5 years ago), and I could always tap on images like logos and they would work. But I don't have any 5 year old devices to try the range slider, so that could very possibly be another thing (in addition to the virtual keyboard) where QML totally outperformed HTML5

You were probably not using js heavy sites on your iPod touch 5 years ago.
