iPhone X vs. iPhone 8: Which New Apple Phone Should You Buy?

The iPhone 8 and iPhone 8 Plus have been overshadowed by iPhone X, but they deserve a little attention because not everyone wants to shell out $1,000+ for an iPhone. For those people, the 4.7-inch iPhone 8 and 5.5-inch iPhone 8 Plus both offer powerful hardware and features like wireless charging, while being a bit more wallet-friendly than iPhone X. But the sleek iPhone X has its advantages. Which one to buy? Read on.

Design and Display

The iPhone X is the phone with all the design changes. You get an edge-to-edge display, a glass front and back, and a highly polished metal band along the sides. The front consists of a smooth expanse of screen that replaces the familiar Touch ID-enabled home button with Face ID sensors set in a cutout at the top.

The iPhone 8 and 8 Plus stick to more traditional looks. They add a glass back for wireless charging, but keep the home button and a regular aspect ratio for a body that's largely identical to iPhone 7 and 7 Plus.


Dimensions are where you'll notice the biggest differences in usability. The iPhone X has a 5.8-inch screen compressed into a body that measures 5.65 by 2.79 by 0.30 inches (HWD) and weighs in at 6.14 ounces.

Compare that with the 4.7-inch iPhone 8 (5.45 by 2.65 by 0.29, 5.22 ounces) and 5.5-inch iPhone 8 Plus (6.24 by 3.07 by 0.30 inches, 7.13 ounces); despite having a bigger screen than the 8 Plus, the iPhone X still has a form factor that's only slightly bigger and an ounce heavier than the iPhone 8. That means when it comes to using it with one hand, the iPhone 8 will be easiest to use, the iPhone X comes in at a close second, and the iPhone 8 Plus will be the biggest, heaviest, and most unwieldy.


All three phones are IP67 water- and dust-resistant, letting them survive in 5 feet of water for half an hour. Headphone jacks are now a thing of the past, but all three support Bluetooth 5.0, which improves range and lets you stream to two pairs of headphones simultaneously.


The difference between the iPhone X display and the ones on the 8 and 8 Plus is like day and night. The iPhone X boasts a 5.8-inch, 2,436-by-1,125 Super Retina HD panel that packs in 458 pixels per inch, the biggest increase in pixel density since the iPhone 6 Plus. By contrast, neither the iPhone 8 (1,334-by-750, 326ppi) or iPhone 8 Plus (1,920-by-1,080, 401ppi) receive an upgrade in resolution or pixel density over the iPhone 7.

Display technology is different, too. The iPhone X's Super Retina HD display is an OLED panel sourced from Samsung, giving users rich, saturated colors and dense, inky blacks. All three phones get Apple's wide color gamut and True Tone display, but only the iPhone X has HDR, allowing for significant visual enhancements on photos, videos, and streamed content. Maximum screen brightness is equally high for all three devices, providing good sunlight visibility. 3D Touch, a feature that dates back to iPhone 6s, lives on.

Processor and Battery

If what's under the hood is most important to you, there's a lot to be pleased about with Apple's new A11 Bionic chipset found in iPhone 8 and X. According to leaked benchmarks on Geekbench, it's the single most powerful processor on a mobile device we've seen, with a single-core score of 4,061 and a multi-core score of 9,959, beating every Android device and all previous iPhones and iPads.

There's also Apple's custom-designed GPU, which should give you strong gaming performance across the board. It wouldn't be an exaggeration to say that these are the three most powerful phones in the world.


We don't have details on battery capacity, but Apple claims iPhone 8 battery life will be similar to iPhone 7. For reference, the iPhone 7 clocked 5 hours, 45 minutes in our battery test—in which we stream full-screen video over LTE at maximum screen brightness—and the 7 Plus clocked 6 hours.

The big winner is the iPhone X. According to Apple, it should last two hours longer than the iPhone 7, giving you nearly 8 hours of runtime. All three phones now support fast charging, letting you juice up to 50 percent in 30 minutes with the iPad adapter.


Camera capability is hard to test without doing a full shootout in PC Labs, but taking into account the hardware gives us a good idea of what each iPhone should be capable of. Starting at the bottom, the iPhone 8 has a single 12-megapixel rear camera with optical image stabilization and quad LED True Tone flash. The lack of a secondary sensor means you don't get telephoto zoom, portrait mode, portrait lighting, or the bokeh effect. The iPhone 8 should work with AR apps, but you may not get depth sensing that's as accurate as a dual sensor setup.


The iPhone 8 Plus has two 12-megapixel rear cameras. One is the standard wide angle lens while the other is telephoto, giving you 2x optical zoom. On 8 Plus, only the wide angle lens has OIS, letting you record stable video and improving low-light shooting. Other features include the shooting in portrait mode and being able to take advantage of Apple's Portrait Lighting feature, which gives you studio-quality lighting effects.

The iPhone X has similar hardware to the 8 Plus, with two 12-megapixel sensors. It also supports 2x optical zoom, Portrait mode, Portrait Lighting, and bokeh. The big advantage of the iPhone X is that both its rear cameras support optical zoom, rather than just one, giving you more consistent quality when it comes to video recording and low-light shooting.


Where iPhone X really pulls ahead is with the 7-megapixel front-facing TrueDepth camera. As the name indicates, this is what scans your face for Face ID. Aside from unlocking, it also boasts a Portrait mode for your selfies, Portrait Lighting, and Animojis, which are animated emoji that track your facial movements. It's a pretty impressive technology, which could have some interesting uses as developers create apps for it.

All three phones have an improved image signal processor for fast autofocus in low light. They're also capable of 4K video recording at 24, 30, and 60fps, and support 1080p slow-mo video recording at 120 or 240fps.

Software and Features

All three new iPhones will come running iOS 11, Apple's latest operating system. It will roll out to all iPhone owners on Sept. 19 and bring with it new features like ARKit's augmented reality support, a file manager, and serious multitasking capabilities. If there's one thing Apple is great at, it's consistent updates, so you have nothing to fear on this front regardless of which iPhone you buy.

Price and Availability

The iPhone 8 and 8 Plus will be available for pre-order starting Sept. 15 and will begin shipping Sept. 22. The iPhone X pre-orders start Oct. 27 and ship Nov. 3.


Price is likely to be the biggest factor in determining which iPhone to buy. Unsurprisingly, the iPhone 8 is the most affordable; the 64GB model will cost you $699 and the 256GB comes in at $849. For the iPhone 8 Plus, you're looking at a starting price of $799 for the 64GB model and $949 for 256GB. The iPhone X, meanwhile, costs a hefty $999 for the 64GB model and $1,149 for 256GB.

Overall, if price is your biggest concern, the iPhone 8 gives you the powerful A11 processor, wireless charging, and some small improvements to camera and display in a compact form factor. If camera quality is a primary concern and you prefer a bigger screen, the iPhone 8 Plus packs in dual rear camera sensors, a larger, higher-resolution display, and most of the features you get with the iPhone X. Finally, if price is no object, the iPhone X is leaps and bounds ahead of iPhone 8 and 8 Plus in terms of design and hardware, incorporating innovative new technology. We'll be testing all three in the coming months, so stay tuned for more details.

PwC staves off disruption with immersive emerging tech training

The big accounting firms are under pressure from digital disruption just like every industry these days, but PwC is trying a proactive approach with a digital accelerator program designed to train employees for the next generation of jobs. To do this, PwC is not just providing some additional training resources and calling it a day. They are allowing employees to take 18 months to two years to completely immerse themselves in learning about a new area. This involves spending half their time on training for their new skill development and half putting that new knowledge to work with clients. PwC’s Sarah McEneaney, digital talent leader at PwC was put in charge of the program. She said that as a consulting organization, it was important to really focus on the providing a new set of skills for the entire group of employees. That would take a serious commitment, concentrating on a set of emerging technologies. They decided to focus on data and analytics, automation and robotics and AI and machine learning. Ray Wang, who is founder and principal analyst at Constellation Research says this is part of a broader trend around preparing employees inside large organizations for future skills. “Almost every organization around the world is worried about the growing skills gap inside their organizations. Reskilling, continuous learning and hand-on training are back in vogue with the improved economy and war for talent,” he said. PwC program takes shape About a year ago the company began designing the program and decided to open it up to everyone in the company from the consulting staff to the support staff with goal of eventually providing a new set of skills across the entire organization of 50,000 employees. As you would expect with a large organization, that started with baby steps. Graphic: Duncan_Andison/Getty Images The company designed the new program as a self-nomination process, rather than having management picked candidates. They wanted self starters, and about 3500 applied. McEneaney considered this a good number, especially since PwC tends to be a risk-averse culture and this was asking employees to leave the normal growth track and take a chance with this new program. Out of the 3500 who applied, they did an initial pilot with 1000 people. She estimates if a majority of the company’s employees eventually opt in to this retraining regimen, it could cost some serious cash, around $100 million. That’s not an insignificant sum, even for a large company like PwC, but McEneaney believes it should pay for itself fairly quickly. As she put it, customers will respect the fact that the company is modernizing and looking at more efficient ways to do the work they are doing today. Making it happen Daniel Krogen, a risk assurance associate at PwC decided to go on the data and analytics track. While he welcomed getting new skills from his company, he admits he was nervous going this route at first because of the typical way his industry has worked in the past. “In the accounting industry you come in and have a track and everyone follows the track. I was worried doing something unique could hinder me if I wasn’t following track,” he said. Graphic: Feodora Chiosea/Getty Images He says those fears were alleviated by senior management encouraging people to join this program and giving participants assurances that they would not be penalized. “The firm is dedicated to pushing this and having how we differentiate this against the industry, and we want to invest in all of our staff and push everyone through this,” Krogen said. McEneaney says she’s a partner at the firm, but it took a change management sell to the executive team and really getting them to look at it as a long-term investment in the future of the business. “I would say a critical factor in the early success of the program has been having buy-in from our senior partner, our CEO and all of his team from the very start,” She reports directly to this team and sees their support and backing as critical to the early success of the program. Getting real Members of the program are given a 3-day orientation. After that they follow a self-directed course work. They are encouraged to work together with other people in the program, and this is especially important since people will bring a range of skills to the subject matter from absolute beginners to those with more advanced understanding. People can meet in an office if they are in the same area or a coffee shop or in an online meeting as they prefer. Each member of the program participates in a Udacity nano-degree program, learning a new set of skills related to whatever technology speciality they have chosen. “We have a pretty flexible culture here…and we trust our people to work in ways that work for them and work together in ways that work for them,” McEneaney explained. The initial program was presented as a 12-18 month digital accelerator tour of duty, Krogen said. “In those 12-18 months, we are dedicated to this program. We could choose another stint or go back to client work and bring those skills to client services that we previously provided.” While this program is really just getting off the ground, it’s a step toward acknowledging the changing face of business and technology. Companies like PwC need to be proactive in terms of preparing their own employees for the next generation of jobs, and that’s something every organization should be considering.
