iPhone XS and XS Max Benchmarked: World's Fastest Phones (Again)

The world's first 7-nanometer processor in a phone isn't the breakthrough that the A11 Bionic was regarding raw performance, but it still runs circles around Android phones powered by Qualcomm's Snapdragon 845 chip in several world real-world tests and synthetic benchmarks.

The new hexa-core chip inside the iPhone XS and XS Max packs two performance cores that are designed to be 15 percent faster than its predecessor, along with four high-efficiency cores that use up to 50 percent less power, according to the company. On top of that is a four-core GPU that Apple says is up to 50 percent faster.

Here are the results so far, based on our testing. If there are any tests you would like us to run in addition to what you see here, please let us know in the comments.

Geekbench 4 (Multicore)

iPhone XS Max11,515
iPhone XS11,420
iPhone X10,357
OnePlus 69,088
Galaxy Note 98,876
LG G7 ThinQ8,566
Galaxy S9+8,295

Geekbench 4 is a benchmark that measures overall performance, and no other phone comes close to Apple's new handsets on this test. The iPhone Xs notched 11,420, and the iPhone Xs Max hit 11,515. The older iPhone X scored 10,357, so that's about an 11 percent improvement.

There's a lot more distance between the new iPhones and Android flagships. The fastest Android phone around, the OnePlus 6, scored 9,088 on Geekbench 4 with its 8GB of RAM, while the Galaxy Note 9 reached 8,876.

*Doesn't support Adobe Clips app

To test real-world performance, we use the Adobe Premiere Clips app to transcode a 2-minute 4K video to 1080p. The iPhone X was miles ahead last year with a time of just 42 seconds. This time around, the iPhone XS and iPhone XS Max knocked it down further to 39 seconds.

The Galaxy S9+ took 2 minutes and 32 seconds to complete the task, and that's the fastest we've seen from an Android phone. The OnePlus 6 finished in 3:45, and the LG G7 ThinQ took 3:16.

iPhone X26 seconds7.2 seconds10 seconds19.7 seconds
Galaxy Note 935 seconds7.2 seconds9.1 seconds29.38 seconds

One good way to measure real-world performance is to see how long it takes for a phone to load demanding apps. Because the phones have the same processor for this round, we just used the iPhone Xs Max and put it up against the iPhone X and the Galaxy Note 9.

The iPhone XS Max was faster every  time, including a 15-second victory in Fortnite over the Note 9 and 3-second win in Asphalt 9. The phones were closer in Pokémon Go but the iPhone XS Max still came out on top.

3DMark Slingshot Extreme (Graphics)

OnePlus 65,124
Galaxy Note 94,639
Galaxy S9+4,634
iPhone XS Max4,339
iPhone XS4,244
LG G7 ThinQ4,201

Here's one test where the new iPhones fell behind. 3DMark Slingshot Extreme measures graphics performance by evaluating everything from rendering to volumetric lighting. The OnePlus 6 fared best in this test with a score of 5,124, followed by the Galaxy Note 9 and S9+. The iPhone XS Max and iPhone X finished behind those handsets.

GFXBench 5.0/Metal


Aztec RuinsCar Chase
iPhone XS Max 1,604.7 frames1,744.44 frames
iPhone XS1,774.1 frames1,674.3 frames
Galaxy Note 9851.7 frames1,103 frames
Galaxy S9+1,339 frames1,783 frames

The new iPhones turned the tables on the GFXBench 5, which is longer and more intense than 3DMark Slingshot Extreme. The Aztec Ruins scene, for example, is highly detailed with complex graphics designed to stress a phone.

The iPhone XS Max achieved 1,604.7 frames on the Aztec Ruins portion of the test, and 1,744.44 frames in the Car Chase test. The Note 9 was far behind at 851.7 and 1,103 frames, respectively. However, the Galaxy S9+ edged past the iPhone XS Max on this test.

Bottom Line

Based on our testing, the A12 Bionic processor inside the iPhone XS and iPhone XS Max make these the fastest phones you can buy. Android phones powered by Qualcomm's Snapdragon 845 chip are speedy but they are a step behind Apple's phones. We plan on conducting more tests, including evaluating LTE speeds on the new iPhones versus other phones, and will add the results to this report.
