Xiaomi is the first global smartphone packing the latest Snapdragon 855 by Qualcomm and it's also the first one we get to put through our usual benchmark tests.
The Snapdragon 855 is built on a high-end 7nm manufacturing process and it's promising plenty of power and efficiency gains over its predecessor.
The new chipset uses an 8-core CPU design with 1x ultra-high-performance Kryo 485 Gold core (Cortex-A76 derivative) running at 2.84GHz, 3x high-performance Kryo 485 Gold at 2.42GHz, and 4x power-efficient Kryo 485 Silver cores (Cortex-A55 derivative) that go up to 1.8GHz.
There is a new Adreno 640 GPU, of course, which supports Vulkan 1.1, HDR Gaming, and Physically Based Rendering. And it should offer some nice performance bump over the 630 in the Snapdragon 845.
There is a new dedicated vision processor that can now process depth mapping at 60 frames per second, which should greatly improve augmented reality applications. The new image processor also allows for 4K HDR capture at 60 fps, all while using 25% less power than its predecessor.
As for 5G, well, Qualcomm isn't putting an X50 modem into every new Snapdragon 855 chip it's making. Instead, some including the one in the Mi 9 will come with the new X24 LTE modem, capable of theoretical download speeds up of to 2Gbps. So Xiaomi Mi 9 doesn't support 5G, while the upcoming Mi Mix 3 5G model will be the company's first to cater to the next gen networks.
The regular Mi 9 comes with 6 GB of RAM and you can choose between 64 and 128 gigs of storage. There will be more premium transparent and Explorer (Pro editions), which feature up to 12GB RAM and 256GB storage.
Finally, the Mi 9 has a Full HD+ screen, which means it has an edge over the 1440p+ phones when it comes to graphics.
And now, let's run some benchmarks.
We start off with some GeekBench torture on the CPU. The new Kryo (Cortex-A76) clocked at 2.84GHz outperforms the A76 cores @2.6GHz within the Kirin 980 (Huawei Mate 20 bunch) - as expected, while comes close to Samsung's custom Mongoose M3 but still can't beat it. Apple is still the leader as far as single-core performance is concerned even if the usual disclaimer for cross-platform comparisons not being perfectly fair is needed here.
Higher is better
When all those new Kryo cores work together, the Mi 9 with its Snapdragon 855 managed to outperform the whole Android bunch and matched the Apple's A12 CPU score. More importantly, the Snapdragon 855 CPU turned out 50% faster than the Snapdragon 845's.
Higher is better
Moving on to some GPU tests, then. The raw performance of the Adreno 640 comes on top of every other GPU we've seen so far in Android smartphone. It demonstrates between 10% and 20% performance bump over the Adreno 630 in the previous Snapdragon (Mi 8 and Mi Mix 3).

And thanks to its 1080p screen resolution the Mi 9 gains even more lead in the onscreen benchmarks.

The 3D Mark SlingShot Extreme Unlimited is quite like AnTuTu - it gives one ultimate score for easy GPU prowess comparison. And the Mi 9 has beaten all other phones we've tested confortably. It scored about 20% more than the Mi Mix 3 and its Adreno 630 GPU.
Higher is better
And now, it's time for the world's most popular compound benchmark for mobiles - AnTuTu. Here, the Mi 9 has channeled all of its power to reach a new record in our database and beat every smartphone, including Apple's, we've tested to this very day.
Higher is better
The Xiaomi Mi 9 and its cutting-edge Snapdragon 855 chip are worthy of a flagship status as far as performance is concerned. The chip offers one of the fastest processors on the Android market, as usual, while its GPU punch delivered by the new Adreno 640 is class-leading and the best money can buy right now.
The Snapdragon 855 is manufactured on the cutting-edge 7nm process, and unlike the Kirin 980 (also 7nm), it heats up considerably less. The chip does release some amount of heat and the Mi 9 does have a few spots that get warm under pressure but that's about it - nothing gets uncomfortably hot. Some throttling may occur after running consecutive benchmark tests but only then.
Qualcomm has delivered an all-around great chip once again with class-leading graphics and competitive processor and the Mi 9 will get all the benefits from being among the first to carry it.
