GPU Performance
GPU performance of the Mi9 will be dictated by how Xiaomi was able to implement the SoC in the physical hardware shell of the phone, and how well it’s able to dissipate the heat throughout the body of the phone. Other factors on the software side such as thermal throttling limits can also greatly impact the results, and as we’ve seen in the S855 we can see very much a wide range of results amongst the many Snapdragon 855 devices.
On the 3DMark Physics test which is a CPU stress test within a GPU thermally constrained power scenario, we see the Mi9 perform very well in the sustained long-term results. It’s not quite as good as the OnePlus 7 Pro or the RedMagic 3, but it beats all other Snapdragon 855 devices.
In the graphics test, the positioning shifts a bit amongst the devices, with the Mi9 falling back to the middle of the pack. Still it’s a good performance given that the Mi9 has one of the lower body masses amongst the phones, and thus not quite as good thermal dissipation abilities.
In GFXBench, we’re seeing again some very good results for the GPU performance of the Mi9, however it stands a bit out that the delta is greater in workloads like T-Rex. Here the large framerates put more stress on the CPU as well as memory of the phone, likely creating more heat and in turn forcing the Mi9 to throttle more.
Overall, the Mi9’s gaming performance was very good and competitive. It’s not the best but it’s also far from the worst amongst Snapdragon 855 devices. The odd thing here is that the Mi9 performs significantly better than Xiaomi’s own Black Shark 2 gaming-oriented phone whose sustained performance just completely collapses in our stress tests. We’ll be reviewing the Black Shark 2 separately in the next few weeks, but things aren’t looking well for that phone.

I'm going to call Bullshit on your scores because I have the Note 9, S9+ and the Xiaomi Mi 9 EU Global ROM and my scores including FPS and a lot of things you have posted here do not come close to the performance I'm getting.My Mi 9 best every phone you have up there in most every one of those test.
It lost to the ROG 2 and Black Shark 2pro in a couple area's but very limited. Matter fact though, what makes anybody with a ounce of common sense know that this testing is completely fabricated bullshit is the fact that the S10+ is up top or near the top in a lot of spots because the S10+ has the worst testing of just about any 855 chipped phone. Furthermore you have the S9+ rated higher in certain test that I personally ran and there are official results from those very testing sites saying your results are off by more then a 1000 points in some areas with the S9+ even.
I don't get the sham going on here but it just ruined any credibility this site ever had!

Are you still using the stock rom? I'm pretty sure AnandTech didn't bother getting the latest greatest(and probably hasn't had it long enough to get unlocked or xiaomi.eu). I know my phone had a huge performance difference after a few updates.Andrei Frumusanu - Friday, September 13, 2019 - link
It's running the latest OTA on a commercial EU unit, build date July 9th. The phone's been out long enough that didn't go finishing for nonpublic firmwares.Redmyth79 - Friday, September 13, 2019 - link
What update? What's the number 10. What?I currently have 10.2.30.0 and have not complaints except for the fact that around the 10.2.26 update I lost the ability to control saturation, sharpness and contrast.

So you understand what I'm calling bullshit on is the performance charts with GPU and CPU test with the many test. The one thing the Xiaomi Mi 9 truly excels at is CPU, GPU and overall speed and gaming experience always running at the top of any flagship out. The only one I've seen close is the OnePlus 7 pro.As far as your end review, I saw your camera info, you are wrong in a few areas here as well.
The Xiaomi Mi 9 does have a advanced EIS that is not like others but is actually a advanced form of OIS with a extra sensor that watches the movement of the OIS to give it more accurate and faster info to make proper adjustments to make the Mi 9 one of the most stable of all current smartphones in 4k@30 video.
Any YouTube reviews and also dxomark will show this without question up amongst all the rest.
If I can post the link to the Mi 9's EIS I will do it here for those to read up on it.
Last, I don't have a issue with low light pics and most reviews show the same bit it's not of the level of the Note 10+, P30 pro or Pixel without Gcam for night shots.

Of course you have to put in the http/www part on that link.

A new fanboy arrives.Redmyth79 - Friday, September 13, 2019 - link
Fanboy of what I've always been a Galaxy fanboy sense I've owned all from S4-S9+ but the Mi 9 is truly a game changer to meNXTwoThou - Friday, September 13, 2019 - link
As a fyi, I've taken some rather craptackular shots with my Mi9. I've also taken some astoundingly good ones. Previously I was Lumia 950 and 920 before that. I'd been used to relatively good cameras on my phones. Lack of OIS is a big deal and the EIS doesn't make up for it. I have some health issues that cause trembles, my older phones it made zero difference, with the Mi9 it's very apparent when I'm having a bad day. Even when I'm not having a bad day I can still get bad shots where the same environment had previously been no issue for my previous phone.The Mi9 is an insanely good value. I love my phone. I just recognize the issues presented in the article are valid.

If you have good benchmarks and data post them rather than ranting.Talk is cheap if you're too afraid to back it up.
Anandtech has years of best in class work around mobile performance analysis. Forgive me if I give them the benefit of the doubt.
