Clearly faster CPU clock speed
4 x 1.2 GHz
2 x 1 GHz
4 x 1.2 GHz vs 2 x 1 GHz—2.40x faster CPU clock speed
Lots higher pixel density
216 ppi vs 170 ppi—27.06% higher pixel density
Sizably more internal storage
16 GB vs 8 GB—8 GB more internal storage
Has branded damage resistant glass
Damage resistant glass (such as Corning Gorilla Glass or Asahi Dragontail Glass) is thin and lightweight, and can withstand high levels of force.
10.45 mm vs 10.5 mm—0.05 mm thinner
Can be charged via standard USB cable
It can be charged and operated with a standard USB cable connected to your computer, or with a USB power supply.
Direct updates by OS vendor
It can be updated directly by the OS vendor, so no need to wait until the manufacturer or network provider releases an update.
Measurably higher resolution
1280x800 px vs 1024x600 px—1.67x higher resolution
Has an IPS screen
IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of normal TFTs TN-matrices: relatively slow response times, small viewing angles and low quality color reproduction.
Appreciably more microphone(s)
2 vs 1 —1 more microphone(s). More microphones result in better sound quality and enable the device to filter out background noise.
Vastly smaller semiconductor size
40 nm vs 45 nm—5 nm smaller semiconductor size. A smaller size indicates that the process to create the chip is newer.
120 mm vs 122.4 mm—2.40 mm narrower
A bit lighter
340 g vs 345 g—5 g lighter
A tad more battery power
4325 mAh vs 4000 mAh—8.13% more battery power
