In what follows, we’re going to compare the iPhone 6s to its predecessor specs-for-spec to see if everything has really changed.

The iPhone 6s and iPhone 6 are very similar, but the iPhone 6s is slightly bigger (138.3 x 67.1 x 7.1mm vs. 138.1 x 67 x 6.9mm) and heavier (143g vs. 129g). The 2015 iPhone comes with a taptic feedback Retina HD display (with 3D Touch multitouch support) that’s partially responsible for the increase in weight, and the device has sturdier metal case made of 7000 Series aluminum.
Processor, memory, and storage
The iPhone 6s and iPhone 6 both have 64-bit processors and motion coprocessors. But the new handset packs a faster, more energy-efficient A9 chip with significantly faster graphics that also happens to have an embedded M9 processor capable of offering always-on functionality.
Memory-wise, the iPhone is expected to pack 2GB of RAM, but that’s yet to be confirmed while the iPhone 6 has 1GB of memory. As for storage, both devices come in the same 16GB, 64GB and 128GB versions. It’s too early to say whether there are any differences in memory quality between them, but pricing is the same.
