System Performance

With the iPhone SE I've decided to make the transition to our 2016 benchmark suite. We've been including some of these for a little while now, and some tests from our previous suite are still around. There is one test omitted, which is Basemark ES / Basemark Metal, which we'll be deploying once we have all the data from this year's flagship Android smartphones. Comparisons to those Android phones will also have to wait until their respective reviews, and for now I can only really compare the iPhone SE to Apple's other iPhones along with 2015's flagship Android devices.

Kraken 1.1 (Chrome/Safari/IE)

WebXPRT 2015 (Chrome/Safari/IE)

JetStream 1.1

At this point I think we're ready to move to our 2016 web browser benchmarks. Octane is now retired, as there's  a large degree of overlap between it and JetStream, with JetStream using a more sensible methodology with measurements for tests like the mandreel-latency test. Kraken, Octane, and Jetstream all have some overlap, but Kraken and JetStream are different enough to make it worth keeping Kraken on. Finally there's WebXPRT 2015, which we already introduced as a replacement for WebXPRT 2013 some time ago. 

As expected, the iPhone SE matches the iPhone 6s in our JavaScript tests. The improvement over the iPhone 5s is significant, with roughly double the performance in all cases. This is right in line with Apple's 2x performance claim, and it's important to note that these are updated iPhone 5s figures run on iOS 9 to ensure that it also benefits from the improvements made to Apple's Nitro JavaScript engine since it launched in 2013.

3DMark Sling Shot Extreme Unlimited ES 3.1 / Metal - Overall

We originally planned to use 3DMark Sling Shot Unlimited, which is an OpenGL ES 3.0 test that runs off screen 1920 x 1080 tests to produce results that are useful for comparing devices and SoCs. However, in the interest of test longevity we have moved to the even newer Sling Shot Extreme test, which uses OpenGL ES 3.1 on Android and Metal on iOS, with a Vulkan version coming to Android in the future. The tests in Sling Shot Extreme render off screen at 2560 x 1440, so it should be a good target for GPU performance well into the future.

In this test the iPhone SE performs well. I experienced a strange situation where the iPhone 6s would consistently score lower than the SE, and I'm not sure if this is due to driver differences or some other problem, but in any case the SE and the 6s both end up at the top of the chart, and the final score is nearly three times higher than that of the iPhone 5s. I'm still waiting on final reviews for this year's Android flagships, so comparisons to Snapdragon 820 and Exynos 8890 will have to wait a bit longer.

GFXBench 3.0 Manhattan (Onscreen)

GFXBench 3.0 Manhattan (Offscreen)

With T-Rex HD being such an old test, I've decided to retire it except perhaps for reviews of devices with relatively slow SoCs. That leaves GFXBench 3.0 Manhattan, and hopefully GFXBench 4.0 in the near future. In Manhattan the iPhone SE performs exceptionally well, achieving a frame rate that is ever so slightly more than three times that of the iPhone 5s. While there's obviously a degree of variance, I think this shows that Apple's 3x GPU performance claim is not an exaggeration, and on such a tiny display with a relatively low resolution you can render a scene like Manhattan at native resolution and almost achieve 60fps.

NAND Performance

With the first generation of the MacBook, Apple introduced their own PCI-E SSD controller with support for NVMe. At the launch of the iPhone 6s and iPad Pro, they noted that both devices had significantly improved storage performance. During the course of our review we discovered that Apple had essentially brought some version of their controller down to their mobile devices, and as a result they led the rest of the mobile market by a large margin when it came to overall storage performance.

With the iPhone SE, Apple uses the same controller as they do in the iPhone 6s and iPad Pro. Since this iPhone is a 64GB unit, we can take a look at the potential impact of a smaller SSD that may not be able to utilize parallelism to achieve the same performance as its 128GB and 256GB counterparts in Apple's other devices. To analyze the storage performance of the iPhone SE I've used StorageBench, a NAND benchmark developed by Eric Patno which is comparable to our AndroBench 3.6 test on Android.

Internal NAND - Random Read

Internal NAND - Random Write

Internal NAND - Sequential Read

Internal NAND - Sequential Write

Despite the fact that the storage capacity is half that of our iPhone 6s review unit, the iPhone SE performs essentially just as well. Random reads actually end up being faster, while random writes are nearly identical. Sequential reads trail the 6s by a bit, but sequential writes end up being identical much like random writes. The differences are enough to attribute to testing variance, and it's probably safe to say that the storage performance on the 64GB iPhone SE is identical to that of the 64GB and 128GB models of the iPhone 6s.

    I think it's less about not having the necessary display tech and more about A) reusing parts and tooling plus B) sticking to the aspect ratios iOS has been made to work well with.

    I don't fundamentally disagree with you tho, but at the same time I wish there were more/better small Android phones so I'm actually glad Apple saw a demand for the SE and put it out there.

    I'm still clinging to a Nexus 5, in 2.5yrs I've seen nothing that has tempted me away from it outside the Z3/5 Compact which would've required a carrier change (still considered it).

    The N5X looked ok, specially at Project Fi prices, just not quite enough... Hopefully there's another small Nexus this year. Otherwise I might give up and try a large phone (S7/HTC 10), ugh.

    I'm with you, my Nexus 5 screen shattered last summer, but the 5X was not impressive to me (still 2 gb of ram?) so I have been holding out for October to see what the new release is. Too many things on my phone are failing now (imagine the dirt, dust, etc. that got in there over the course of a year) but rather than shell out $400+ I went to swappa and found a 32 gb Mint Nexus 5 for $135. Unless something is horribly wrong with it (in which case I can return it) that phone will be plenty "good enough" until hopefully October 2017 when 14/16 nm is matured. Reply

    Before anyone asks why I would need more than 2 Gb of ram, I am constantly having apps evicted, even when there is only one app going. For example, playing a game, I get a text. I reply to the text, and when I go back to the game, it had been evicted from ram and I have to completely re-load it. If I am going to shell out for a brand new phone, no way I will get one with less than 3 gb of ram. Reply

    Games are probably the worst case scenario in that regard, possibly followed by heavy camera use... I don't do/use much of either on my phone so I've gotten along just fine with 2 GB. I think the phone actually manages RAM better now than when it launched on Lollipop. Reply

    1. Get used to it. Bezels are there for a purpose.
    2. And yet people complain about fingerprint sensors on other device as "too fast".
    3. Stop taking selfies.
    4. You gotta be kidding me.
    5. It's also 5.1".

    You need the bezels, at least on the side - makes it much easier to access the sides of the screen with a case on. People have to give up and the bezel argument - iPhone users like the bezel size. Reply

    I wouldn't go as far as to say iphone users like me and a lot of people i know that use iphones hate the bezels. I have a 6s plus that feels bigger than my brothers phone which has a larger screen. I like my iphone but they can decresase the damn bezels anytime!! Reply

    In typical anandtech iPhone review fashion, it didn't take long for the "this review is so biased" comment to show up. Reply

    I think the 5s design is the best so far. I found that the curved edges on the 6/6+ are too slippery compared to the hard edges on the 5s.

    Also, the button-click feel on iPhones are so much better than anything on Android. Buttons on Android phones are so mushy feeling, it really cheapens their experience.

    I'm really surprised apple went to flagship parity on the internals while using the same part number for the front screen. Good job apple! Reply
