We saw that the Mali T628 in the Kirin 920 is quite power hungry, but let's see exactly how much performance it delivers for that power.

3DMark 1.2 Unlimited - Graphics

3DMark 1.2 Unlimited - Overall

The 3DMark graphics score falls in the middle inbetween the Adreno 320 and the Adreno 330. Due to the low physics score on the CPU side, the overall score is quite low compared to other flagships.

BaseMark X 1.1 - Overall (High Quality)

There's a similar trend going on with BaseMark X, the Kirin manages to outperform the Adreno 320 but can't touch the Adreno 330. In many cases it performs roughly at half the speed of competing flagships. Only when enabling the "Rog" mode and dropping to 720p does the GPU catch up the Adreno 330. In fact we can pretty much say that the Mali in the HiSilicon chip performs identically in 720p as the Adreno 330 does in 1080p. I'm suspecting a severe lack of fill-rate power on behalf of the Mali GPU.

This trend continues on to the GFXBench 3.0 tests. Interestingly, the performance delta is much smaller for the Manhattan test and is not that far off from the Adreno 330 as it was in the T-Rex. In 720p it catches up with the Adreno 330 on T-Rex and surpasses it in Manhattan. This again might indicate that the Mali has more ALU power and is bound by other factors in the T-Rex test. A look at the fill-rate tests confirm this suspicion, as it ends up slower than the Mali 450MP4 in the Kirin 910T:

GFXBench 3.0 Fill Rate Test (Onscreen)

GFXBench 3.0 Fill Rate Test (Offscreen)

It seems the MP4 configuration is too underpowerd to properly run 1080p content at optimal performance, its fillrate scores are quite poor and the GPU is even outperformed by architectures two generations behind.

GFXBench 3.0 Quality/Accuracy Test (Medium Precision)

GFXBench 3.0 Quality/Accuracy Test (High Precision)

An noticeable result is found in the accuracy tests of GFXBench: the Mali achieves consistently higher scores over the competition. While in no way noticeable, this would mean that ARM's drivers are doing a better work of rendering the intended scene.

All in all, the GPU is decidedly mid-range. If you plan on gaming a lot on your smartphone, a Hi3630 device such as the Honor 6 or Ascend Mate 7 may not deliver an experience as good as a competing device with a Qualcomm SoC.

    Kirin920/925 is very intrasting SoC compared with MediaTek 6595( 4 cortex A17, 4 cortex A17 GPU PowerVR6200) in mid phone class 200-300$ Reply

    As someone who doesn't game, this SoC is pretty interesting. Being interested in mainly web performance, this phone looks fairly attractive for the price. This obsession with phone/tablet GPU performance is a bit puzzling, and there should be options with strong CPU performance and middling GPU performance for those of us who only do casual or once-in-a-blue-moon phone/tablet gaming. What percentage of tablet users are utilizing the full power of their Tegra K1 GPU, or phone users utilizing the full power or their Snapdragon 801 (Adreno 330) GPU? My bet is few. Reply

    Whoops, I forgot there's only one K1 tablet out right now, and it's a gaming one! So probably 100% of K1 users ARE utilizing that fullness of that GPU! Reply

    if im not mistaken, there are 2 K1 Tablets that are out right now. MiPad , and Shield. Reply

    how do you burn through 3100mAh in 1.6483 hours that is beyond me Reply

    By having it use about 6W/hr;) Reply

    Great having reviews for chinese only phones! They are great! Nubias, Meizu, Xiaomi, Huawei. Please keep going reviewing this stuff Reply

    I just want to note something that is not brought up nearly as much or at all, the lighting that affects the screens... over many years I've seen screen look better then other in certain light and in other light other screens come out ahead. Long story short, my Nexus 5 looks much better in the sun then my friends iPhone 5c.. the colors seam to be almost *enhanced* if you will while the iPhone although very clear in the sun still looked washed out. Also if you have polorized glassed on the iPhone screen gets wired (kind cool lol) and the Nexus 5 is perfectly visible both vertically and horizontally (the Nexus 4's screen would go totally black if it was held sideways with polarized glasses on).

    So despite not being as bright outright, it handles sunlight hitting the screen much much better then a iPhone 5//5s/5c, especially with glasses on.

    Nice looking phone. Too bad about the crappy wifi and flash performance, because that should be a dealbreaker for almost anyone. Reply

    I have a Huawei Ascend Mate2, and it has a non removable battery. Considering it is a 4000mAH battery, it doesn't matter. Even with a 6.1" screen, it lasts 2-3 days on average. Some have questioned when they released it with a Snapdragon 400 SOC along with a 720p screen. I even had doubts until I started seeing reviews & actual users that have it. Some also questioned the lack of kit kat, sticking it with JB 4.3, but, I bet the majority of users won't care. It's fast, the screen is crystal clear, unless you are a pixel peeper that holds the device 2 inches from your nose! If more and more "mid spec" devices start showing promise, perhaps the days of over priced super spec devices will start to dissipate. Do you "really" need an 8 core 1080p screen? The apps can't really take advantage of all that speed anyway. Reply
