iPhone 8 Plus vs. iPhone X: Spec showdown

0
4

For the first time, Apple has not just two sizes of its newest iPhone, but two distinctly different iPhones. There’s the iPhone 8 and the iPhone 8 Plus, which keep the same form-factor we know and love, Retina display, Home button, and all. And then there’s the new hotness, the bleeding-edge iPhone X, with an OLED display and a TrueDepth camera that unlocks the phone when you look at it.

You’ll notice that Apple didn’t call the iPhone X the “iPhone Pro,” to match the naming scheme of the iPad and MacBook lines. That may be because inside, the iPhone X and the iPhone 8 Plus are really pretty similar. They do have some key differences, however. So without further adieu, here’s a complete spec comparison between the iPhone X and the iPhone 8 Plus.

iPhone 8 Plus vs. iPhone X: Size

The iPhone 8 Plus is the bigger phone, even though the iPhone X’s display is actually larger when measured diagonally.

The iPhone 8 Plus has a 5.5-inch screen, but it’s surrounded by a bezel with the FaceTime camera on the forehead and the traditional Home button on the chin.

Even though the iPhone X has a slightly larger screen, the iPhone 8 Plus is bigger and heavier. 

On the other hand, the iPhone X has a 5.8-inch screen, but it’s in a more compact package with nearly no bezel, no Home button, and a little “notch” for the front-facing TrueDepth camera system.

iPhone X: 5.65 x 2.79 x 0.30 inch, 6.14 ounces

iPhone 8 Plus vs. iPhone X: Display

The biggest difference between these iPhones is the display. The iPhone 8 Plus sports the same Retina display as it has in prior generations, an LCD that in the Plus size is full HD at 1920×1080.

The iPhone X features a 5.8-inch Super Retina HD HDR display.

Apple completely changed that with the iPhone X. It has an edge-to-edge OLED display, which gives it a much higher contrast ratio and support for HDR video. It’s got a higher resolution (2436×1125) and pixel density too—Apple’s even calling it “Super Retina.”

iPhone 8 Plus: 5.5-inch, 1920×1080 LCD, 401 ppi, 1300:1 contrast ratio
iPhone X: 5.8-inch, 2436×1125 OLED, HDR, 458 ppi, 1,000,000:1 contrast ratio

iPhone 8 Plus vs. iPhone X: Performance

Inside, the differences aren’t so stark. Both phones pack the same processor, Apple’s 64-bit A11 Bionic system-on-a-chip with an embedded M11 motion coprocessor. Both also have a dedicated neural engine to let AI processing happen on the device.

The A11 Bionic chip and M11 coprocessor will enable smooth AR experiences in iOS 11.

The A11 Bionic has a whopping six cores: Two for high-performance computing, and four efficiency cores for tasks that don’t require as much performance—or as much power. Apple says the A11 is 75 percent faster than the previous generation. But benchmarks between the two phones should be pretty similar.

iPhone 8 Plus vs. iPhone X: Battery

If battery life is the most important to you, the iPhone 8 Plus with its physically bigger battery should eke out a little more life during Internet use and video streaming, although Apple estimates about the same battery life for talk time and audio playback.

Both of these iPhones support Qi wireless charging, and Apple wil have its own charging pad next year, although plenty of Qi products exist already.

Apple’s own AirPower charging station is coming in 2018.

Both phones also support fast charging if you spring for one of Apple’s USB-C power adapters and a USB-C to Lightning cable. It’s speedy, though: Up to 50 percent charge in just half an hour.

And of course you can always charge up the old-fashioned way too: A standard Lightning cable and USB power brick are still included.

iPhone X: Up to 21 hours talk time, 12 hours Internet use, 13 hours video playback, 60 hours audio playback

iPhone 8 Plus vs. iPhone X: Rear camera

The iPhone 8 Plus still has an edge over the regular iPhone 8 when it comes to camera features. But the iPhone X has the same dual-lens camera on the back as the iPhone 8 Plus, and the same video recording features too.

On the iPhone X, the two cameras are stacked vertically, while on the iPhone 8 Plus they’re side by side. 

The one little difference is that the iPhone X has “dual optical image stabilization,” meaning it works on both of the rear lenses, while the iPhone 8 Plus has just “optical image stabilization,” according to Apple.

iPhone 8 Plus vs. iPhone X: Front cameras

The front-facing cameras on these two phones are so different, Apple gave them different names.

The iPhone 8 Plus has the traditional FaceTime camera, but it has been improved. With a f/2.2 aperture, it takes 7-megapixel stills and records 1080p video. Like the rear cameras, it captures wide-gamut color when taking photos and Live Photos. There’s a Retina screen flash to help you get better lighting for your selfies.

Phil Schiller describes the sensors and emitters in the TrueDepth camera on the iPhone X.

The iPhone X has all of those same features, but its TrueDepth camera goes a lot further. Since you log in to your iPhone X with the new Face ID feature, the TrueDepth camera has special sensors that assist in this secure facial recognition. They include an infrared camera to see you in the dark, a proximity sensor, a flood illuminator, and a dot projector that helps make a 3D map of your face to make sure you’re not a photo.

Animoji mimics your expressions and lip-syncs as you speak. 

All the tech in the TrueDepth camera is packed into the little “notch” at the top of the iPhone X screen, and it helps this camera have extra features for taking selfies too. Namely, it supports the same Portrait mode and (beta) Portrait Lighting feature as the rear-facing camera. Plus, it has Animoji, a feature that animates an emoji (like a puppy, a unicorn, or yes, a talking poop) with your voice as you speak. It’s a silly way to show off this much technology, but it’s another thing that’ll be fun to demo for friends after you show them how you can unlock your iPhone X by just looking at it.

iPhone 8 Plus vs. iPhone X: Biometrics

The iPhone X is all screen, which means it doesn’t have a Home button, which means it doesn’t have Touch ID. Instead, Apple uses Face ID to unlock the phone as well as to authorize Apple Pay payments. Third-party apps can also support Face ID to log in, just as they can also use Touch ID.

Face ID and Touch ID create a digital hash based on your face or fingerprint, respectively, and securely store it in the Secure Enclave, a separate coprocessor that handles security features on the device. Then when you log in or authorize a payment, the new facial or fingerprint data you’re inputting is compared with the stored data, and if it doesn’t match, you still get the option of entering your passcode (to log in), or your password (to sign in to a third-party app or make an iTunes Store purchase, for example).

iphonex faceid setup appleApple

You’ll set up Face ID much in the same way you set up Touch ID, by scanning every angle of your face. 

Around iOS, Face ID works like Touch ID. You do have to be looking at the iPhone. You can temporarily disable Face ID with a five quick presses of the Sleep button, or by squeezing the Sleep and a volume button at the same time. Or you can turn off Face ID for various features (unlocking your phone, for example) in the Face ID & Passcode section of the Settings app.

On the iPhone 8 Plus, it’s Touch ID as normal. The Touch ID sensor is crazy fast, too, and less likely to be fooled, if you’re worried about that. Specifically, Phil Schiller joked onstage at the iPhone X unveiling that an “evil twin” (identical twin, natch) could potentially fool Face ID—but even identical twins have different fingerprints.

iPhone 8 Plus vs. iPhone X: Price and storage

This probably isn’t a surprise, but the iPhone X costs more. After all, the TrueDepth camera is brand-new to Apple, and the edge-to-edge OLED screen must be more expensive and difficult to manufacture.

In fact, if you only know one thing about the iPhone X, it’s probably, “That’s the iPhone that costs $1,000.” And it does—it’s $200 more than the iPhone 8 Plus, and $300 more than the iPhone 8.

The iPhone 8 Plus is $200 less than the iPhone X, and should be easier to find too.

To be (a little bit) fair, iPhone X and iPhone 8 Plus are Apple’s two most expensive handsets. All the way at the low end, the iPhone SE starts at $349, and Apple still offers the iPhone 6s, iPhone 6s Plus, iPhone 7, and iPhone 7 Plus at various price points in between.

iPhone 8 Plus: $799 for 64GB, $949 for 256GB. (iPhone 8 is $699 for 64GB, $849 for 256GB.)

iPhone X: $999 for 64GB, $1149 for 256GB.

iPhone 8 Plus vs. iPhone X: Availability

The epilogue to this story is this: The iPhone 8 Plus will likely be a lot easier to find. The iPhone X comes out later (it goes on sale November 3, with preorders October 27), and will probably be quite scarce in stores, being first-generation technology and all. If you’re shopping around the holidays, you’ll probably find more deals and sales involving the iPhone 8 Plus and iPhone 8 (as well as previous years’ models) than the iPhone X, too.

This isn’t to ding the iPhone X, but some shoppers might wind up going with the iPhone 8 Plus because they can buy one, rather than dealing with the hassle of tracking down the iPhone X in the right color, capacity, and carrier.
