[Xiaomi Poco F1 Guides, News, & Discussion] iamsubhranil:
So I was pretty unsatisfied about the advertised and actual performance of the device in terms of benchmarks, atleast in the default version of the MIUI installed. Strangely, the graphics and the storage performance was much inferior than all other 845 flagships.

But then I saw few people on youtube posting increased benchmark results after flashing MIUI 10. I was intrigued by this, and to test whether or not this conception is actually correct, I decided to note down the numbers myself.

At the end of the day, the result is still not entirely clear, due to the fact that somehow 3DMark's OpenGL ES 3.0 and 3.1 tests were unable to run on MIUI 10 (8.9.4).

Okay enough talking, let's see the numbers. Also, unless otherwise mentioned, on the top is MIUI 9, on the bottom is MIUI 10. Both debloated.

As you can see, the score is pretty low on MIUI 9 and faaar below the advertised as well as the average. MIUI 10 however, does justice.

Not only the graphics score is much better, the storage score is also heavily increased. Here are the detailed scores shown below.

Now, on the light of recent events (the OEMs cheating in benchmarks), I was skeptical. To check whether similar trend continues or not, next up, I put GeekBench's CPU test.

Alright, CPU performance seems unchanged, just like Antutu reported. Let's try the GPU (Compute) Test.

Say what? GeekBench is reporting much lower RenderScript scores on MIUI 10 than 9. Is it really some kind of "special modification" by Xiaomi for Antutu? I'm not quite sure. I would have if 3DMark would have run, but now, I'm really that not impressed. Some GFXBench results do show some improvements on FPSs for some tests, but others remained same.

Let's check out the storage performance.

So at least some sigh of relief. As reported by Androbench, the storage performance is indeed increased in all categories.

To double check, I ran PCMark's storage benchmark too.

So, in conclusion, storage performance is indeed increased on MIUI 10.

Overall I'm liking MIUI 10 way too much. It's battery performance is also much much better than MIUI 9. But the whole Antutu thing made the numbers look very fishy.

Now, I don't want to conclude anything. By part, because 3DMark didn't run, and by another part, because MIUI 10 is still in closed beta. All in all, MIUI 10 looks very promising, and no doubt it will get more polish before it officially comes out.

Hopefully 3DMark will run smoothly by then and give us some concrete numbers to reach to the conclusion.
