Technical characteristics of the Snapdragon 730 in Xiaomi Mi 9T

The Qualcomm Snapdragon 730 was announced in April 2019 and was one of the first mid-range chipsets built on an 8-nanometer process, which significantly improved energy efficiency compared to previous generations (for example, the Snapdragon 710, which was produced at the 10nm norm).

The main parameters of the chipset:

• 🔹 Central processing unit (CPU): 8 core-configuration 2+6 (2 Kryo production cores 470 Gold on frequency to 2.2 GHz and 6 energy-efficient Kryo 470 Silver at frequency to 1.8 GHz).
• 🎮 Graphics processor (GPU): Adreno 618 with Vulkan 1.1 support and improved graphics processing for games.
• 📱 Modem: Snapdragon X15 LTE maximum loading speed up to 800 Mbit/s (in real life conditions, about a 300-400 Mbit/s).
• 🤖 Artificial intelligence: a separate Hexagon 688 unit for processing machine learning tasks (e.g., photo enhancement in mode) AI).
• 📷 Camera support: up to 192 MP (single module) or 22 MPP + 22 MP (dual camera), video recording in 4K@30fps.

It is important to note that the Snapdragon 730 does not support 5G networks – this limitation is valid for all devices based on it, including the Mi 9T. Also, the chipset lacks a separate neuroprocessor for deep learning (unlike the flagship Snapdragon 8xx), but for most tasks its performance is more than enough.

Architecture and performance: what gives the Snapdragon 730

The Kryo 470 architecture, which underpins the Snapdragon 730, is a modification of the Cortex-A76 cores (for performance clusters) and the Cortex-A55 cores (for energy-efficient ones), which allows the smartphone to quickly cope with everyday tasks without consuming too much energy.

In synthetic tests (such as AnTuTu or Geekbench), the Mi 9T scores the following:

In real life, the Snapdragon 730 is as follows:

• 📱 Everyday tasks: instant application opening, smooth scrolling of the interface MIUI, Lack of lags in multitasking (up to) 10-15 simultaneously open applications).
• 🎮 Games: PUBG Mobile and Free Fire are working at high settings with FPS ~40-50, But in heavy scenes, there may be drawdowns to 30 Genshin Impact requires cutting graphics to average.
• 📸 Photography: image processing in mode HDR Or Night Mode takes over. 1-2 Seconds, which is faster than many budget smartphones.
• 🔋 Energy consumption: with moderate use (social networks, messengers) smartphone holds a charge 1.5-2 In games, the discharge accelerates to 4-5% hourly.

💡

If your Mi 9T is starting to warm up in games, try limiting the FPS to 30 fps in the graphics settings. This will reduce the load on the processor and prolong battery life.

Comparison with other processors: who is stronger?

To see how good the Snapdragon 730 is, compare it to chipsets in the same price range and close-in-time competitors.

The main rivals:

• 🔥 Kirin 810 (Huawei Nova 5T): Exceeds in single-threaded tasks, but loses in the schedule (Mali-G52 vs Adreno 618).
• 🔥 Helio G90T (Redmi Note 8 Pro: Better optimized for gaming, but worse in energy efficiency (12nm process technology).
• 🔥 Exynos 9611 (Samsung Galaxy A51): weaker in performance but supports 108 MP cameras.
• 🔥 Snapdragon 720G (POCO X2): It is almost identical, but with a little bit of a slack. GPU (Adreno 618 is 10% faster).

The Snapdragon 730’s key advantage over its competitors is the balance between performance and energy efficiency. The Helio G90T, for example, can perform better in games, but it warms up more and burns the battery faster. And the Kirin 810, despite its high single-threaded performance, suffers from optimization problems in some applications.

When it comes to flagship chipsets (like the Snapdragon 855 or Kirin 980), the performance gap is around 30-40%, but for most users, the difference is subtle in everyday tasks, with the exception of heavy gaming or professional video processing.
