In addition to what zurn said, they also don't specify the exact Core i3 model number (it could be an older generation), the RAM speed, and if the data set fits in cache.

If RAM access is needed ARM machines usually fall behind quickly, since they usually have much lower RAM bandwidth.

The model number used for the evaluation is Core™ i3-530

That's a Westmere from Jan 2010. Westmere -> Sandy Bridge -> Ivy Bridge -> Haswell.

Comparing with something from 3.5 years and 3 generations ago is useful?

Copy pasting my reply once again.

You are right that the i3 CPU(Core i3-530) we compared with is a little old generation. I tried to compare online Core i3-530 with Core i3-2105. The 2105 is SandyBridge(couldnt find a direct comparison with an Ivy Bridge) and runs at a slightly higher clock 3.1 GHz(while the 530 runs at 2.93 according to CPU world).

According to cpu-world. The 2105 is 21% faster than the 530 for single threaded operations. If you account for the speed in clock this would mean only a boost of 14% improvement over the 530.

So its really not such a bad comparison.

In the meanwhile we will try run this on a newer CPU and let you know the results.
