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.
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.
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.
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.

total bullshit..Brakken - Friday, June 5, 2015 - link
I'm curious - why would anyone buy something like this? Free can be had anywhere - even older models of iPhones can be had for free with a contract. These Chinese things offer nothing new, including underpowered hardware and unsupported software. I have to admit though - this thing beautifully blends the champhered edges of the iPh5 and the speaker grills of the iPh6/iPod5.Ethos Evoss - Friday, June 12, 2015 - link
I think u really need to visit eye surgery ! same edges like on iphone really ?? speaker grills same like on iP6 ?? ar u sure u not blind or u have completely blurred eyes???Have you ever seen the galaxy S6 or S6 edge and took a lok at its bottom of phone u EYE cripple?

What are the chances of Huawei sending a phone with a cherry picked calibrated display?Andrei Frumusanu - Thursday, June 4, 2015 - link
Close to zero. This was one of the units they have out to all the attendees of the London launch event. Given the bad backlight bleed of this unit it's highly likely they're not picked. Plus I had to figure out myself that setting the temperature to minimum will make it accurate.cknobman - Thursday, June 4, 2015 - link
Slow CPU and GPUBad display
Poor camera
Slow charge time
Terrible WiFi performance
Not cheap
Is there any good reason to buy one of these things?

Did you read the review? Andrei said the camera's great, it's just everything else that's bad. Like so:"While the camera is the phone's truly outstanding feature, the whole device as a package just seems to underperform on too many other areas to be able to justify a purchase."

It's JUST everything else that's bad? That's a pretty damning statement, if you ask me. And the camera didn't perform all that well in the easiest situation—outdoors in sunlight. Not so great after all.
