CPU & System Performance

As mentioned in the introduction of the P8, the new Kirin 930 SoC is an octa-core A53 with one low-power quad-core cluster with a frequency range going from 403MHz up to 1516MHz, and another high-powered cluster going from 1017MHz up to 2016MHz. I was able to determine that the L2 cache size of the high-performance cluster comes in at 512KB, but due to no available rooting mechanisms for the device I couldn't manipulate the device to lock our benchmark tool onto the small cores to determine their exact configuration.

Generally, due to this being an A53 device, we shouldn't be expecting any stellar performance as ARM's little core is about 2-2.5 times slower as an equivalently clocked larger architecture such as an A15 or A57 CPU. So while Huawei ramps up the clocks quite high at 2GHz, it's still very much more of a mid-range performer.

As expected, our in-browser benchmarks put the P8 at the lower-end of the performance spectrum as it simply doesn't have enough processing power to keep up with the competition. I also tested out to see if the stock browser would have any optimizations, but it performed more or less the same as Chrome. This makes sense as compiler targets shouldn't affect an in-order architecture such as the A53 as much as larger and more complex cores as ARM's big lineup of CPUs.

While the Javascript benchmarks represent a good insight in performance when browsing websites in a browser, it's far more common for users to experience web content via third-party applications which make use of a built-in WebView frame, in which case the OS's WebKit engine is used.

PCMark is such a test, where we can analyse performance numbers more representative of daily use-cases.

PCMark - Web Browsing

In the Web Browsing test, the P8 manages to land in the middle of the crowd. We saw large performance improvements coming from the Android 5.0 Lolipop update on several of our devices, and we're still in the process of updating all devices to the latest firmware to be able to re-test them.

PCMark - Video Playback

Oddly enough, the P8 mananges to take the top spot in the Video Playback test as several other Lolipop devices regressed in this test when compared to KitKat.

PCMark - Writing

The Writing test is a sub-test which is very sensitive to actual OS and runtime optimizations; Huawei's KitKat devices performed horribly in this test as they suffered from some very obvious problem with Dalvik. Luckily the P8 and the combination of ART (Android RunTime) of Android 5.0 manage to keep it performing very well with other flagship devices.

PCMark - Photo Editing

The Photo Editing test uses RenderScript to offload processing algorithms to the GPU. The Kirin 930's Mali T628MP4 performs averagely as it struggles to keep up with the beefier implementations and optimized drivers of other devices.

PCMark - Work Performance Overall

Continuing on to BaseMark OS II 2.0, which is another similar real-world benchmark which measures system performance influenced by the runtime and APIs.

Basemark OS II 2.0 - System

The system benchmark of BaseMark OS is more processing power oriented, as as such, the A53 cores don't perform as well in this test. 

Basemark OS II 2.0 - Memory

Surprisingly, the P8 performed excellently in the memory test. This is a benchmark which stresses the NAND and CPUs. Huawei has made huge improvements over the low-speed NAND which was implemented in the Honor 6 and Mate 7, and as we'll later see in the in the more throrough eMMC testing, has paid off well for the P8 as we see performance differences of night and day.

Basemark OS II 2.0 - Graphics

The Mali GPU sadly again finishes among the last of the bunch, as it looks like combination of a smaller core implementation and older drivers puts the P8 among its bretheren Kirin SoCs at the bottom of the graphics test.

Basemark OS II 2.0 - Web

The web test is again a CPU heavy test and the A53 only ends up with average performance.

Basemark OS II 2.0 - Overall

Again, the overall score ends up average for the P8. In every-day usage the device still manages to be quite fast even though it can't be compared to other flagship devices with stronger SoCs. HiSilicon especially seems to have some issues with fluid performance when CPU demand spikes very strongly, as one will notice small stutters throughout some apps when more heavy processing is being performed, something I often reproduce on other big.LITTLE SoCs when I disable aggressive scheduler migrations.

    I am an iPhone 6+ user but I have no problem this review uses Galaxy S6 camera for comparison as the S6 have an excellent camera. The SONY RGBW sensor in this camera might be used in the upcoming iPhone 6S in September and it will be interesting to see with SONY and Apple's refinement how it will stack up against Note 5 and G4.
  • serendip - Friday, June 5, 2015 - link

    Huawei should really stop with this Kirin nonsense. The modem sucks power, the SOC's power management is a joke, yet Huawei are crazy enough to charge flagship prices for a midrange phone that struggles to keep up with much cheaper offerings. A Mi Note is a cheaper and better option.

    I know this isn't a nexus review but these charts would look rather different if a nexus 5 running 5.1 and a nexus 6 on 5.1 were used since Lollipop 5.1 finally brought a lot of changes into android that were manufacturer dependent. The nexus 5 on 5.1 posts better random writes than any of the phones on this list for example.
  • OOwl - Saturday, June 6, 2015 - link

    I do agree with you in terms of 5.1 improvements. I am currently testing a small upcoming Motorola handset and although it's not a monster in terms of power and should be on paper lower powered than the processor in the P8 Lite, it is soo much more responsive. Battery life is also rather underwhelming on these Kirin SoC powered handsets...

    just picked this up on contract for £21x12, or looked at another way; ~£250 for a phone with 300m/5000t/1gb.

    for that price its flaws pale into insignificance.
  • sunnohh - Sunday, June 7, 2015 - link

    Jelly, 1 year contracts across the pond! Extremely low rates. Don't tell me you get reliable service everywhere.
  • R3MF - Sunday, June 7, 2015 - link

    i live in a rural area, we never get reliable service. :)
  • sunnohh - Sunday, June 7, 2015 - link

    I pay 45$ for unlimited call text and 5gig data through wal mart's plan that uses an AT&T sim. Nexus 5 is about 97% reliable, but it's bring your own phone. Which around here is the exception rather than the rule. The rule being Verizon near 100% reliability and exhorbinate rates and long contracts with obscene break up fees.
  • Ethos Evoss - Friday, June 12, 2015 - link

    Jeeezus anandatech u made me sweat PROPERLY I finished this mega ,tera hexa .. eem .. NO !
    I will go rather other way ...
    It took me over and hour to finish this mini, micro , nano , piko , errr.. I'll skip rather all metrics and I'll jump directly to deep ATOM review I have EVER seen in my life ..
    ALWAYS when it comes to Huawei devices especially to find EVERY single NEGATIVYTY to their products..
    I will say you are MOST weirdest website in actual WORLD ..
    But that's fine that is your probably style to do autopsy to find weakness..
    To summarize your (in few ways) misleading review to pull people off buying phone bcos of bribed by apple or who knows who doesn't bother me .. but u are cowards anyway ..
    we can start :

    1.introduction and design:

    * ''only supports UE Category 4 LTE speeds, reaching up to 150Mbps downstream and 50Mpbs upstream.''
    -So u claiming that this phone supports LTECat 4 only ?? u liying or u have wrong info as this phone supports LTECat 6 !

    *''We had some very harsh words for Mate 7’s camera performances, as both featured very disappointing photo and video quality.''
    -Ecxuse me ?? I have feeling that u HAS no experience of taking pictures at all I own Mate 7 and everybody says that my pictures on phone are amazing WTF u trying to say weirdos?? liars! isheep!

    *''This is the second kind of implementation RGBW (Or RGBC) after the OmniVision unit found in the original Moto X.''
    -yeah why u higlighting it IT WAAS second?? why nobody been talking about it THEN in crappy fail moto x ? what u trying to protect ? or put itno negativneses ?? so WHAT if it''s second ?seriously!

    *''It should be noted that the black frame surrounding the actual screen makes it seem as if the device’s size-bezels are much smaller than what they really are, something which is very visible on the lighter coloured models.''
    -yeah u picked white version so what u been expecting ?? so stupid every phone which is in withe color must have black borders jesus christ u are unbelieveable .. did u mention this in crapple iphone 6 review? you need more knowledge that if u have black screen version u don't notice any borders! mentals..

    *''Huawei called the design a “single audio chamber speaker system”, but in practice the right grill is essentially just for aesthetics and only serves as a housing for the bottom microphone. Covering up the left grill will completely dampen the audio output of the device.''
    -eem excuse me and what is the problem that phone has simetrical grills which gives better look ?!?
    on your crapple phone wht is there 5 holes on right side and 2 on the left how rubbish crap looking !
    dampen audio ?? oh yeah even iphone 5 or 6 or s6 or edge has dampen audio bcos everybody covers holes so obviously sound will be dampen WTF u mentiong this SHT??1?!!? ar u nuts?

    * camera module seems to be still 1.5mm underneath the glass.
    -ar u serious with this mention ?? jeezus christ .. u are total weirdos FOR REAL ! ATOM REVIEW!

    *''he only gripe I’ve had with it is that it seems to have some empty space underneath the back of the phone as if you try to squeeze it will flex inwards by up to 1mm''
    - Whaaaaa??? OMG what THE HELL are you doing with smartphones seriously u need HELP !

    2.Software - EmotionUI 3.1

    *''Huawei continues the choice of not including an application drawer with the EmUI launcher, so all installed apps are placed on the launcher screens.''
    -So what? BETTER NOT complain here as u wud have to complain to your beloved iphone so u rather stayed quiet right ?

    *''It would be appreciated if Huawei had at least included the option to disable app-icon framing throughout the OS''
    -I NEVER EVER heard in my life that SOMEBODY wud comes up with this NON-SENSE sht called ''app-icon framing throughout '' trully u are word inventors ! ... app icon framing .. jeezus christ ..

    *''I've praised Huawei's inclusion of a per-app permission manager in the Honor 6 and Mate 7, and it sadly seems that the P8 drops this practice as it no longer is exposed to the user''
    -the reason why they didn't include this feature anymore was because all constant annoying remind to close all important apps and services which needs to be running and users been complaining by not receiving notifications , locations not found ! in other phones never been why it bothers you now???

    *Although the P8 lacks a fingerprint sensor ''
    -trully who uses it?? nobody .. only gay geeks with their glasses 200 bioptries

    *''a feature where one would double-tap or draw with a knuckle to capture a screenshot''
    -I believe if u root the phone which is easy to do so .. u can nicely disable this feature in file systems (eg build prop)

    3.CPU & System Performance

    I really NOT going to break down this section as there are 1000 negativeness I would be here till next christmas..
    Simply your bars, graphs and compares ARE TOTAL POINTLESS/USELESS t
    Completely obsolete as I browse or edit on my mate 7 or on P7 perfectly no problems as any other phone.
    I noticed that If iphone or any other phone you adore has less or shame/laughable results u simply not include it in your graphs .. u cowards ..!

    4.GPU Performance

    Same as above no comment on useless completely not REAL world results as everybody plays games on the phone without any issues .. or play films.. on P7 we normally watch youtube vids in 1080p or 720p without problem ..
    yeah your pathetic iphone can be on top but good luck it its even crappier battery which will stay last half a day or less !

    5.WiFi Performance and nand

    I really don't understand another pointless tests of wifi performance ..
    it is clearly USELESS /POINTLESS to have strong wifi another battery drain ??
    Wake up, u measuring NETWORK speed instead of INTERNET speed ! What u wanna tell me now u playing multiplayer over smartphones behind desks like idiots like onPC where wifi network speed is inevitable
    Pleease DON'T be naive, Huawei instead of you THINK and don't implment stupidly highest wifi module tuner radio JUST for pointless network speed which nobody will NEVER use it for every day use ! Everybody needs fast internet download speed for quick loading pages or downloading files don't you think ? And this P8 managing at best ! Yu fkin thanks god u didn't unsolder wifi chip to check if it's OK or what.. myyy gooosh ..

    * While the new eMMC doesn't break any records, it's now among the "average" performing devices out there, as opposed to the horrendous performances of the Mate 7 and Honor 6
    -horrendous .. wow so dramatic? I never noticed any horrendous like u oddly describing - bitching !

    6.Display Measurement and power

    *''together with a NovaTek NT35695 display controller IC''
    -jez so u mentioning controller wt-hell and u can tell us brands of capacitors and resistors too ? i think that is important too n ?

    *''I noticed a very weird behaviour of the display's brightness that cannot be explained by usual mechanisms such as CABC. The OS clearly alters brightness depending on the application - for example using a browser such as the stock one or Chrome, along with other random applications such as Dropbox or FX Explorer will cause a dimming in the display, if one opens up the recents menu or goes back to the home-screen then one can see how the backlight brightens up. One would think this can be explained with by assuming the default launcher and OS elements are allowed a higher luminosity than other apps, but I've discovered that many other apps don't dim the display.''
    - Right here is ONLY first thing right now I can agree with this issue ... yes I have noticed dimming in chrome but u didn't consider it is caused by app ? the chrome app causing this and some others because when u open chrome it auto changes resolution don't thik that you surfing in 1080p ...
    this happens to me with my mate 7 so i just increase brightnes a bit and volia .. problem solved..

    *''Huawei P8 backlight bleed''
    Every phone with ips screen has bleed it is caused by stress which is put by phone frame where screen glass lies .. i means that you will NEVER craft housing middle frame bezel 100% straight by machine .. it would have to be laser machine NOT CnC .. so when screen is placed into frame there is significant bend , squeeze of glass ass glass is slightly bendable elastic

    Huawei's GREAT feature which NO ONE phone has it is white Color temperature
    In this case , I will call it ; this new case (new and new IPS technologies comes across) this neo-ips screen it seems that is not playing together with color temperature feature..
    As it perfectly works with M7(mate7) P7 I have color temperature set nearly to max about 85% !
    Looks like due to new IPS technology and that RGBW or RGBC feature in LCD has conflict !
    In this case (as been this explained in warm results and cold results) It is necessary that once user will be watching films or photos will have to change color temp to warm and WHEN will be surfing on internet and reading text definately slide it to the cooler side ... (not max as it result bluish distortion)

    7.Battery life and charging

    Again your beloved iphone has to be on top.. aaahh well ...
    I truly doubt it is better than mate 7 .. rubbish .. ppl saying it has not great battery at all ..
    I won't comment this
    In my real world battery life on my mate 7 is nearly two days and on my GF's P7 is whole day ..
    I don't genuinely believe your iphone or others has better battery .. NO chance !
    For charge I don't mind as I charge phone over night so in morning all is ready ...

    8./9.Camera and video

    Only to say that seen couple vids on youtub or pics on parena or Garena and ppl managed to make nice, great photos so don't really understand your AGAIN so much hatress to this phone
    I agree video recording is not good part but pictures are very good and even at night ..

    10.
    DISASTER ... ANANDATECH ....YOU are ICON of the internet
    I will name you KINGS of WEIRDO-GEEKS ... :DDDDD
    Huawei haters from unknown reason ... bribed by apple ? to keep your site above water..? as everybody corrupted smartphone sites..
    Remember Huawei phones ARE NOT for any performance .. you are brainwashed by your fixed bug in head that all in the world HAS to be highest, fastest, best... you are all wrong..
    Huawei manuf. they DID described it what they phones are for.. for what use
    Firstly for elegance , then smart look, for smart ppl not for kids like you type; aah that is sloow that is crap I don't want it gpu and cpuu is sloow..
    This smartphone is for grown ppl grown man in suits , for managers, for social women in beautiful dress they love nice and sleek and slim light design, which they will stick this review into your ass and we will say ''WE SIMPLY DO NOT CARE'' if it's not highest specs. GTFOOO

    The "T-Rex Offscreen Power Efficiency" is pretty useful. Could you perform the same test on Tegra X1, Tegra K1, A8x, Snapdragon 810 and Snapdragon 801?
