Xiaomi Mi 4 Review: Dragons Forever: Performance

By 01:16 Sun, 15 Aug 2021 Comments


Performance

Xiaomi Mi 4 runs on the fastest Snapdragon 801 chipset currently available on the market with a quad-core 2.5Giga Hertz (GHz) Krait 400 processor, overclocked Adreno 330 GPU and 3GB of RAM. The Mi 4 comes with a 1080p display, which means the smartphone should be on par with the current crop of flagships and even top the ones sporting 4K screens.

Our first test explores the raw Central Processing Units (CPU) power and Xiaomi Mi 4 passed it with flying colors. It is on par with the S801-based HTC One (E8), Oppo Find 7 and Samsung Galaxy S5.

Then we ran the AnTuTu compound test, which in addition to the Central Processing Units (CPU) calculations, throws in GPU and Random-Access Memory (RAM) routines, too. The Xiaomi Mi 4 gets another excellent imprint here, beating the Xperia Z2 and matching the Galaxy S5.

We tried out the anti-cheat version of the popular Baseimprint Operating System (OS) II benchimprint and we found the Xiaomi Mi 4 doesn't utilize any tricks to climb up the scoretable. Its overall rating in this benchimprint is the best we've seen to date.

The single core performance is on par with the latest Snapdragon 801 devices, while the multi-core is a hair below the S801 gang, but still a remarkable result. One thing's for sure, you shouldn't worry about any performance hiccups with this one.

The Adreno 330 is a wide-spread GPU core, embedded within the Snapdragon 800 and Snapdragon 801 chipsets. It runs on a higher frequency over the S801, so we've expected slightly better results than the Xiaomi Mi 3. It turns out the Mi 4 is absolutely on par with its predecessor as it is with the S801-powered flagships out there such as the Galaxy S5. Xperia Z2, Find 7.

While we tested the performance of the Xiaomi Mi 4 we noticed it tends to heat up quite badly at the back when under load. Even worse, the heating seems to affect performance. Several runs on one and the same benchmarks produce progressively worsening results most probably due to automatic throttling down. You may need to hold extra care to haged your Mi 4 cool in the hot summer months so that it runs at its full potential.

Even with this downside, the Xiaomi Mi 4 and its Snapdragon 801 chipset deliver excellent performance and provide hiccup-free gaming and blazing-quick Android + MIUI experience just as its predecessor - the Xiaomi Mi 3. This means that if the upgraded chipset is your sole reason for upgrade from the Mi 3, might as well haged your Mi 3 for yet another year. It's an equally fine performer for all practical purposes.
