iPhone X and iPhone 8 Are World's Fastest Phones (It's Not Even Close)

Update 12/21: We've added results from the iPhone X.

The "Bionic" part in the name of Apple's A11 Bionic chip isn't just marketing speak. It's the most powerful processor ever put in a mobile phone. We've put this chip -- which powers the iPhone 8, iPhone 8 Plus and iPhone X -- to the test in both synthetic benchmarks and some real-world speed trials, and it obliterates every Android phone we tested.

As a quick primer, the A11 Bionic is a six-core CPU, with two performance cores that promise a 25-percent boost in performance and four high-efficiency cores that promise up to a 70-percent improvement over the iPhone 7's A10 Fusion chip. Last but not least is an Apple-designed GPU that's supposed to be 30 percent faster than before.

Let's start with Geekbench 4, which measures overall performance. On the multicore portion of this test, the iPhone 8 hit 10,170. That's 54 percent faster than the score from Samsung's Galaxy Note 8 — currently the fastest Android phone. The iPhone X scored 10,357 on the same test.

The Android competition wasn't close. The Note 8 scored 6,564, and that's with an impressive 6GB of RAM paired with Qualcomm's fast Snapdragon 835 chip. How about the OnePlus 5 and its 8GB of RAM and Snapdragon 835? That handset got 6,542. With 4GB of RAM, the Galaxy S8 scored 6,295 with the same processor.

The iPhone 8 even edged out the score from the 13-inch Apple MacBook Pro with a 7th-generation Core i5 processor. That notebook notched 9,213. Is Geekbench 4 really comparable from phone to desktop? According to the founder of Geekbench, John Poole, “the short is answer is yes that the scores are comparable across platforms, so if an iPhone 8 scores higher than an i5, then the iPhone 8 is faster than the i5.”

However, Poole provided the important caveat that laptops are better at delivering sustained performance over a longer period of time, as opposed to the shorter max burst performance that benchmarks like Geekbench 4 are designed to measure. In other words, the iPhone 8 simply doesn’t have the thermals and heat dissipation necessary to replace your laptop.

Next up is 3DMark, which gauges graphics performance. The iPhone 8 scored an off-the-charts 62,212, and the iPhone 8 Plus managed an even higher 64,412. Compare that to the Note 8's 39,834 and the OnePlus 5's 39,576.

If you're wondering how all this translates to real-world performance, we have more good news for iPhone 8 shoppers — and bad news for everyone else. To really put the A11 Bionic chip through its paces, we put the same 2-minute video, shot in 4K by a drone, on the iPhone 8, Galaxy Note 8 and Galaxy S8+, and then added the same transitions and effects before exporting and saving the video.

The iPhone 8 and iPhone X finished this strenuous task in just 42 seconds, while the Note 8 took more than 3 minutes. The Galaxy S8+ took more than 4 minutes.

How about opening a large file? We downloaded a 5.1 MB map illustration PDF to both the iPhone 8 and Galaxy Note 8 and opened them from their native file managers: the Apple Files app and the My Files app. The iPhone 8 averaged under 0.8 seconds, while the Note 8 averaged 6.41 seconds.

The iPhone 8 also opened more demanding apps faster than its predecessor and the top Android phone right now, although those differences were less dramatic. It took the iPhone 8 11 seconds to fully load the Injustice 2 game, compared to 14.53 seconds for the iPhone 7 Plus and 19 seconds for the Note 8.

Of course, there are lots of ways to measure performance, but based on our testing thus far, the iPhone 8 is easily the fastest phone ever. Now everyone else has to play catchup.

    Regardless your benchmark tests are so different from others, so where did you get these figures from? Other reputable sites have different results. Regardless, Apple I-phones always seem to be faster but when the real test comes in, like opening up a web page or even some files, they are much slower than Android and I know because I have both phones.

    Would have been useful to see how it compares to the iPhone 7, too.

    You should probably keep in mind that the phones they’ve compared it to are also nearly a thousand dollars.

    Relax. These results are simply stating the processor is years ahead of those in new android phones. The results never told you to get an iPhone. If you like android than buy it. Simple as that.

    You're thinking of the iPhone X. This is the iPhone 8.

    Go ahead and list them. This seems to be exactly in line with every other review I've seen. It's not like the Geekbench scores are changing, either.

    Totally false. That's the iPhone 7 killing the latest.
