Qualcomm Snapdragon 8 Gen 3 vs MediaTek Dimensity 9300: Full Comparison
Introduction
Choosing a smartphone often involves looking at the processor that powers it, as this chipset is central to performance, efficiency, and feature support. In the premium segment, the Qualcomm Snapdragon 8 Gen 3 and MediaTek Dimensity 9300 represent two of the most advanced options available. This comparison breaks down their architectures, performance characteristics, and key technologies to help you understand their differences and similarities. We will examine their CPU and GPU designs, AI capabilities, connectivity, and overall efficiency.
CPU Architecture and Performance
The fundamental difference between these two chips lies in their CPU core configurations, which leads to distinct performance profiles.
- Snapdragon 8 Gen 3: It uses a more conventional “1+5+2” core layout: one prime Cortex-X4 core, five performance Cortex-A720 cores, and two efficiency Cortex-A520 cores. This setup is generally designed to balance high peak performance with power efficiency for everyday tasks.
- Dimensity 9300: MediaTek opted for a radical “All-Big-Core” design with a “4+4” configuration: four Cortex-X4 prime cores and four Cortex-A720 performance cores. It lacks dedicated low-power efficiency cores. This architecture aims for extremely high multi-threaded and peak CPU performance, relying on advanced power management to handle less demanding tasks.
In benchmarks, the Dimensity 9300 often shows a lead in multi-core CPU tests due to its four X4 cores, while single-core performance is typically very close. Real-world performance can vary significantly based on device cooling and manufacturer tuning.
GPU and Gaming
Both platforms include powerful, next-generation graphics processors capable of handling demanding mobile games.
- Snapdragon 8 Gen 3: Features the Adreno 750 GPU. Qualcomm’s Adreno GPUs have a strong reputation for consistent performance and driver support. It supports hardware-accelerated ray tracing and is often the GPU of choice for many game developers when optimizing titles.
- Dimensity 9300: Equipped with the ARM Immortalis-G720 GPU. This GPU also offers hardware-based ray tracing and is known for its high theoretical peak performance. Its real-world efficiency and sustained performance in games depend heavily on the thermal design of the smartphone.
Gaming performance is highly competitive, with each GPU leading in different titles. The Snapdragon platform may have a slight edge in terms of widespread game optimization in most regions.
AI and Machine Learning
Artificial intelligence processing is a critical component for camera features, voice assistants, and on-device generative AI.
- Snapdragon 8 Gen 3: Integrates the Hexagon NPU (Neural Processing Unit). Qualcomm has emphasized its capability for on-device generative AI models, supporting multi-modal models that can run entirely on the phone without a cloud connection.
- Dimensity 9300: Includes MediaTek’s next-generation APU (AI Processing Unit) 790. It is also designed for efficient generative AI workloads, boasting high performance on popular AI benchmarks and supporting large language models (LLMs) on-device.
Both NPUs are exceptionally powerful, and the practical AI features users experience will depend more on how smartphone manufacturers implement them in software and camera applications.
Connectivity and Manufacturing
These areas highlight the integrated technologies that support network speeds and influence power consumption.
- Modem: The Snapdragon 8 Gen 3 includes the Snapdragon X75 5G modem, which is often cited for its advanced power efficiency and support for the latest 5G standards. The Dimensity 9300 uses MediaTek’s integrated 5G modem, which also supports fast sub-6GHz and mmWave speeds.
- Manufacturing Process: Both chips are built on a 4nm process technology, which contributes to their performance and efficiency. However, they are produced by different foundries (TSMC for both, but potentially different “N4P” variants), which can lead to subtle differences in power characteristics.
- Wi-Fi & Bluetooth: Both support the latest Wi-Fi 7 and Bluetooth 5.4 standards.

Frequently Asked Questions (FAQ)
What is the main difference between the Snapdragon 8 Gen 3 and Dimensity 9300?
The most significant difference is the CPU architecture. The Dimensity 9300 uses an “All-Big-Core” design with four high-performance cores and four mid-performance cores, aiming for maximum multi-threaded power. The Snapdragon 8 Gen 3 uses a more traditional setup with one prime core, five performance cores, and two efficiency cores, focusing on a balance of peak performance and power efficiency.
Which chipset is better for gaming?
Both are excellent for gaming. The Adreno GPU in the Snapdragon chip has a long history of strong optimization with game developers. The Immortalis-G720 in the Dimensity chip offers very high peak performance. The actual gaming experience can depend on the specific game, graphics settings, and the cooling system of the smartphone housing the chip.
Does the Dimensity 9300 consume more battery than the Snapdragon 8 Gen 3?
Due to its lack of dedicated low-power cores, there was initial speculation about higher power consumption for the Dimensity 9300. However, through advanced power management and process technology, real-world battery life in devices using each chipset is more dependent on the overall phone design, software optimization, and battery capacity than on the chipset alone.
Which chip has better AI performance?
Both feature dedicated, powerful NPUs (Hexagon and APU) capable of on-device generative AI. They perform very closely on standard AI benchmarks. The perceived AI performance for a user will typically come from the specific camera and software features that phone manufacturers build using these AI capabilities.
Final Thoughts
The Qualcomm Snapdragon 8 Gen 3 and MediaTek Dimensity 9300 represent two different philosophical approaches to achieving top-tier performance.
