Xiaomi 12: Snapdragon 8 Gen 1 processor – a full overview of the characteristics and capabilities

The Xiaomi 12 smartphone became one of the flagship devices of the brand in 2022, which attracted attention not only with a stylish design, but also with a powerful “stuffing”. The central element of any modern technology is the processor – it determines the speed, energy efficiency and capabilities of the device. In the case of Xiaomi 12, we are talking about the top Qualcomm Snapdragon 8 Gen 1, which at the time of its release was considered one of the most productive solutions for Android smartphones.

But many users are asking: How does this processor cope with everyday tasks? How relevant is it today, a few years after its release? And should you choose the Xiaomi 12 in 2026, given the advent of new models? In this article, we will analyze in detail the characteristics of the Snapdragon 8 Gen 1, compare it with competitors, analyze the results of benchmarks and give practical recommendations for optimizing the performance of the smartphone.

Special attention will be paid to such aspects as heat generation and trottling - the famous "pain" of the first generation of 4-nm chipsets Qualcomm. Also you will learn what games and applications "pull" Xiaomi 12 without lags, and how to properly configure the device for maximum performance.

Specifications of Snapdragon 8 Gen 1 in Xiaomi 12

Qualcomm Snapdragon 8 Gen 1 chipset (codename) SM8450) became the first flagship processor of the company, released on 4-nm process technology (TSMC). This allowed the number of transistors to increase to 8 billion while maintaining energy efficiency:

• 🔥 1 × Cortex-X2 Up to 3.0 GHz – responsible for peak loads (games, rendering, multitasking).
• ⚡ 3 × Cortex-A710 Frequency up to 2.5 GHz – Balance between performance and energy consumption.
• ⚙️ 4 × Cortex-A510 Up to 1.8 GHz – energy efficient cores for background tasks.

The Adreno 730 graphics accelerator provides support for Vulkan 1.3, OpenCL 2.0 and hardware ray tracing.This makes the Xiaomi 12 suitable for modern mobile games such as Genshin Impact or Call of Duty: Mobile at maximum settings.

Separately, it is worth noting the Snapdragon modem X65, network-supporting 5G peak-speed 10 Gbit/s. In pair with the processor works ISP Spectra 680 — It allows you to shoot video in resolution. 8K@30fps or 4K@120fps supportive HDR10+.

It is important to understand that Xiaomi 12 uses a modified version of the Snapdragon 8 Gen 1 with improved cooling. Unlike the base version of the chipset, it uses a Vapor Chamber system (steam chamber), which reduces the temperature by 5-10°C under intense loads.

💡

If you plan to play on Xiaomi 12, turn on Performance mode in the battery settings (Settings) → Battery. → Performance mode. This will reduce trottling, but reduce battery life.

Performance and benchmarks: how the Snapdragon 8 Gen 1 is showing up today

At the time of its 2022 release, the Snapdragon 8 Gen 1 was leading the performance rankings, overtaking rivals MediaTek (Dimensity 9000) and Samsung (Exynos 2200).However, more advanced chipsets such as the Snapdragon 8 have come along over time.+ Gen 1 and Snapdragon 8 Gen 2. How Xiaomi 12 looks against the background of modern flagships?

Based on the results of tests in AnTuTu (v10), Xiaomi 12 scores around 850,000-900,000 points (depending on firmware and temperature:

• 📱 Snapdragon 8+ Gen 1 (2022): 1 100 000+ score
• 📱 Dimensity 9200 (2023): 1 250 000+ score
• 📱 Apple A16 Bionic (iPhone 14 Pro): 950,000-1,000,000 points

In Geekbench 6, the picture is similar:

• 🧠 Single-Core: 1,200–1,300 points (vs. 1,800)+ Snapdragon 8 Gen 3).
• 🖥️ Multi-Core: 3,800–4,200 points (vs. 7,000)+ chip-wise).

Despite the lag behind the current flagships, the Snapdragon 8 Gen 1 remains a powerful processor for most tasks:

✅ Photos in Lightroom Mobile without delay.

✅ Starting games on high settings (PUBG Mobile at 90. FPS, Genshin Impact at 60 FPS).

✅ Multitasking with 5–7 Appendices in the background (thanks) 8/12 GB RAM depending on the modification).

However, there are weaknesses:

⚠️ Trottling: with long loads (more than 20-30 minutes of games), the frequency of the cores drops by 20-30%, which leads to a drawdown FPS.

⚠️ Heating: the body temperature can reach 45-50°C in games, which is uncomfortable for the hands.

💡

The Xiaomi 12 is suitable for gamers, but requires a break every 20-30 minutes to avoid overheating.

Comparison with competitors: Snapdragon 8 Gen 1 vs Dimensity 9000 vs Exynos 2200

In 2022, the Snapdragon 8 Gen 1 competed with two major chipsets: MediaTek Dimensity 9000 and Samsung Exynos 2200. Let's break down their key differences in the context of Xiaomi 12.

🔹 MediaTek Dimensity 9000:

• ✅ Benefits: Better energy efficiency (4 nm from the TSMC), colder in operation, high frequency of the core Cortex-X2 (3.05 GHz).
• ❌ Disadvantages: weaker in schedule (Mali-G710 Adreno 730, better optimized for gaming.

🔹 Samsung Exynos 2200:

• ✅ Advantages: graphics accelerator in architecture AMD RDNA 2 (better for ray tracing).
• ❌ Disadvantages: Made at 4 nm from Samsung (worse than Samsung) TSMC), heavy overheating, productivity drawdown.

🔹 Qualcomm Snapdragon 8 Gen 1 (in Xiaomi 12):

• ✅ Benefits: Balanced performance, better game support (thanks to Adreno), stable camera experience.
• ❌ Disadvantages: high heat, trottling with long loads.

So Xiaomi 12 with Snapdragon 8 Gen 1 is in the middle: it's not the coldest or the most productive, but it offers the best balance for most users. If you want stability in games and photos, that's a good choice. If autonomy is the priority, you better look at the devices on Dimensity 9000.

Real Tests: Games, Videos and Multitasking

To see what Xiaomi 12 is capable of in 2026, we tested it in real-world scenarios.

🎮 Games:

• 🏆 Genshin Impact: 60 FPS on average settings, 40-45 FPS After 25 minutes, the game starts to slow down because of the trottling.
• 🔫 Call of Duty: Mobile: 90 FPS stable, but the body heats up to 47°C.
• 🏀 NBA 2K Mobile: 60 FPS without drawdowns, the temperature is kept within 40-42°C.

🎥 Video editing and rendering:

• ✂️ Adobe Premiere Rush: Exporting Video 4K@30fps borrower ~15 minutes against ~10 minutes on Snapdragon 8 Gen 2).
• 📸 Lightroom Mobile: Processing RAW-24 MP photo – 3-5 seconds per image.

📱 Multitasking:

• 📱 With simultaneous launch of Telegram, Chrome (10 tabs), YouTube (playback in the background), Google Maps and Spotify – no hangings.
• ⚠️ When adding heavy play (for example, PUBG) In the background it takes up to 2-3 applications (depending on the version) MIUI).

⚠️ Note: If you use Xiaomi 12 to stream games via Xbox Cloud Gaming or GeForce NOW, We recommend connecting the gamepad via cable. When using Bluetooth, input delays up to 50–100 ms due to the load on the processor are possible.

To improve performance in games, you can use hidden settings MIUI:

Enable the "Performance" mode in the battery settings

Disable background activity of unnecessary applications (Settings) → Annexes → Permits → Auto-start)

Set a limit FPS 60 fps to reduce heat

Use a cooler or play in a ventilated room-->

Cooling and trottling: how to deal with overheating

One of the main problems with the Snapdragon 8 Gen 1 is overheating. In Xiaomi 12, this problem is partially solved by the steam chamber, but under intense loads, the temperature still rises.

🔥 Hardware techniques:

• 🧊 Use a cooling case or fan stand (e.g. Black Shark FunCooler Pro).
• 🔌 Play with a connected charger (but no more than 30 minutes – this accelerates battery wear and tear).

⚙️ Programmatic methods:

• ❄️ Set performance limits through Settings → Battery. → Balanced regime.
• 🔄 Clean the cache regularly (Settings) → Memory. → Cleanup).

📊 Trottling test results (30 minutes of Genshin Impact at maximum):

• 🕒 0-10 minutes: 60 FPS, 42°C.
• 🕒 10-20 minutes: 50-55 FPS, 46°C.
• 🕒 20-30 minutes: 40-45 FPS, temperature°C+ (trottilling).

⚠️ Note: If your Xiaomi 12 is hotter than 50°C in simple tasks (for example, watching videos), this may indicate problems with thermopaste, in which case we recommend contacting the service center for diagnosis.

Applications can be used to monitor the temperature and frequencies of the processor:

• 📊 CPU Throttling Test - shows performance drawdown.
• 🌡️ AIDA64 — nucleate, GPU battery.
