iPhone X vs iPhone 8 vs iPhone 7: Comparing The Best Of Apple Inc.

Updated on

With the next generation Apple smartphones now unveiled, this is the perfect time to make the iPhone X vs iPhone 8 vs iPhone 7 comparison. There is no doubt that many consumers will be carefully considering which one of these smartphones to purchase. So here is ValueWalk’s verdict on the three major Apple smartphones.


  • iPhone X – 143.6 x 70.9 x 7.7 mm (5.65 x 2.79 x 0.30 in)
  • iPhone 8 – 138.4 x 67.3 x 7.3 mm (5.45 x 2.65 x 0.29 in)
  • iPhone 7 – 138.3 x 67.1 x 7.1 mm (5.44 x 2.64 x 0.28 in)

The iPhone X is undoubtedly the largest of these three smartphones, and there is barely any size disparity between the iPhone 8 and iPhone 7. However, the wraparound display of the iPhone X ensures that this smartphone is not hugely larger than the two smartphones, meaning that the new OLED iPhone is by no means as unwieldy as some people consider the iPhone 8 Plus to be.


However, the iPhone X is somewhat heavier than either the iPhone 8 or iPhone 7, weighing in at 174g. even the iPhone 8 is 10g heavier than the extremely light iPhone 7, which weighs only 138g. This means that the oldest smartphone of the three is the most compact, and this is undoubtedly a significant selling point, even if the difference of 10g between the iPhone 7 and iPhone 8 can be considered rather trivial.


In the iPhone X vs iPhone 8 vs iPhone 7 comparison, the displays included in the three devices are obviously of critical importance. And it is therefore notable that the iPhone X has a screen that is 20 percent larger than either the iPhone 8 or iPhone 7, despite the relatively small disparity in size between the three devices. It is unquestionably a massive selling point of the new OLED handset, and one that will undoubtedly lead to massive sales.

  • iPhone X – 1125 x 2436 pixels, 19.5:9 ratio (~458 ppi density)
  • iPhone 8 – 750 x 1334 pixels (~326 ppi density)
  • iPhone 7 – 750 x 1334 pixels (~326 ppi density)

Similarly, in the iPhone X vs iPhone 8 vs iPhone 7 comparison, the iPhone X completely outperforms the two smartphones in this department, being capable of displaying nearly double the amount of pixels of either of the two other devices. This quad HD smartphone delivers by far the best screen in the history of the iPhone range, while both the smartphone versions of the iPhone series are shy of providing full HD resolution.


Camera technology can often be difficult to compare, so here firstly is a rundown of the specifications of these three devices in this department.

  • iPhone X – Dual 12 MP, f/1.8 & f/2.4, phase detection autofocus, OIS, 2x optical zoom, quad-LED (dual tone) flash
  • iPhone 8 – 12 MP, f/1.8, 28mm, phase detection autofocus, OIS, quad-LED (dual tone) flash
  • iPhone 7 – 12 MP, f/1.8, 28mm, phase detection autofocus, OIS, quad-LED (dual tone) flash

In the iPhone X vs iPhone 8 vs iPhone 7 battle, the camera provisions and photographic capabilities of the three devices are undoubtedly of critical importance. So it is immediately important to know that the iPhone X is the only handset of the three to feature a dual-camera setup. This obviously means that its photographic capabilities are significantly superior to either the iPhone 8 or iPhone 7.

Additionally, the iPhone X includes a 2x optical zoom option which provides extra functionality. It has already been noted that the camera in the iPhone X is far superior to either the iPhone 8 or iPhone 7, and this will definitely be a major selling point when the iPhone X finally arrives in the stores.


The hexa-core processor included in both the iPhone X and iPhone 8 is clearly superior to the quad-core unit that the iPhone 7 relies on. This will ensure that the performance of these next-generation devices is superior to that of the iPhone 7.

The iPhone X is armed with an extra GB of memory in comparison it to the iPhone 8 and iPhone 7, being fitted with 3GB of RAM.


Each of these smartphones feature a maximum memory quantity of 256GB, but the iPhone 7 also has 32GB and 128GB variants that no longer appear in the iPhone 8 / iPhone X generation. Instead, the newer smartphones have a 64GB model that is the entry-level version.


The iPhone X phablet has by far the largest battery of the three devices, which it clearly needs in order to accommodate its larger display. The 2,716 mAh battery of the iPhone X should help reduce criticism of the lifecycle of Apple products, as it is around 40 percent larger than the cell included in the iPhone 7. However, it is perhaps surprising that the battery in the iPhone 8 is smaller than the iPhone 7, even though there have been afew problems reported with battery lifecycle as of yet.


Naturally, in the iPhone X vs iPhone 8 vs iPhone 7 comparison, pricing is of critical importance. It is notable that the price tag of the iPhone X, $999, is virtually double the amount that the iPhone 7 can now be purchased for. The older Apple smartphone is available on Amazon.com for just $520, with the iPhone 8 available now at $699. Clearly the OLED screen comes at a premium, but it does deliver some outstanding features and specs that are worth shelling out for.
