HTC One (M8) vs HTC One (M7) vs Galaxy S4 specs comparison

This is actually the biggest hardware gap with the new HTC One, when compared to its predecessor, as the rest of the specs are pretty similar. All three phones sport 1080p displays and 2 GB of RAM, so the silicon power advantage is entirely on the side of the new HTC One. It also adds a microSD slot for storage expansion - something that its predecessor doesn't have - putting it on equal footing with the Galaxy S4 in that regard, too.

When it comes to the cameras, the new Duo shooter of HTC is certainly something unique in terms of post-shot effects it allows you to do with your pictures. Its main unit, however, is the same 4 MP UltraPixel camera that debuted with the HTC One, while the Galaxy S4 flaunts an excellent 13 MP shooter on its back. In terms of battery capacity, the S4 and the new One are equals, while the older HTC One lags a bit behind, but capacity isn't the whole story. All in all, the new HTC One is a sufficient enough leap over last year's edition, though you might want to hold your horses if you are not sold on the uniqueness of its Duo Camera's options.
