It uses four ultra-performance Cortex-X4 cores and four performance Cortex-A720 cores, completely omitting traditional low-power efficiency cores. This configuration can offer exceptional multi-core and burst performance but relies on advanced power management for lighter workloads.
GPU and Gaming Capabilities
Both chipsets integrate powerful graphics processors to handle demanding games and visual applications.
- Snapdragon 8 Gen 3: It utilizes the Adreno 750 GPU. Qualcomm’s Adreno GPUs are often noted for their strong driver support and consistent performance in a wide range of titles. The chipset supports hardware-accelerated ray tracing and various gaming-focused features.
- Dimensity 9300 Plus: This platform features the ARM Immortalis-G720 GPU. The “All Big Core” CPU can assist in reducing bottlenecks in complex game scenes. It also supports hardware-based ray tracing and MediaTek’s own suite of gaming optimization technologies.
In synthetic benchmarks, their GPU performance is typically very close, with trade-offs that can vary by specific game title and optimization.
AI and Machine Learning
AI processing is a critical component of modern chipsets, enabling features from camera enhancements to on-device language models.
- Snapdragon 8 Gen 3: It includes the Hexagon NPU (Neural Processing Unit). Qualcomm has emphasized its ability to run generative AI models on-device, supporting multi-modal models for text, image, and speech.
- Dimensity 9300 Plus: MediaTek integrates its APU 790 AI processor. It is also designed for efficient generative AI workloads, boasting support for large language models with billions of parameters directly on the device.
The performance and efficiency of these NPUs are often showcased in specific AI benchmark tests, with both companies claiming leadership in different metrics.
Connectivity and Modem
Connectivity is another area where these platforms showcase their integrated technologies.
- Snapdragon 8 Gen 3: It features the integrated Snapdragon X75 5G modem. This modem supports advanced 5G technologies, including carrier aggregation and power-saving features. It also typically includes the FastConnect 7800 system for Wi-Fi 7 and Bluetooth 5.4.
- Dimensity 9300 Plus: This chipset integrates the MediaTek 5G modem, supporting similar advanced 5G standards. It also comes with support for Wi-Fi 7 and the latest Bluetooth standards. Performance in real-world network conditions can be influenced by regional band support and OEM implementation.

Frequently Asked Questions (FAQ)
What is the main architectural difference between these two chipsets?
The primary difference is in the CPU design. The Snapdragon 8 Gen 3 uses a hybrid setup with one prime core, five performance cores, and two efficiency cores. The Dimensity 9300 Plus uses an “All Big Core” design with four ultra-performance cores and four performance cores, omitting dedicated low-power efficiency cores.
Which chipset is generally better for gaming?
Both are extremely capable for gaming. The Adreno GPU in the Snapdragon platform has a long history of strong game optimization. The Dimensity 9300 Plus, with its powerful CPU array, may handle CPU-intensive game scenes very effectively. Real-world performance can depend on the specific game’s optimization for each platform.
Does the “All Big Core” design affect battery life?
It can influence power management. While the Dimensity 9300 Plus lacks small cores, it uses techniques like core scheduling and clock gating to manage power during lighter tasks. The Snapdragon 8 Gen 3’s dedicated efficiency cores are traditionally designed to handle background tasks with lower power consumption. Actual battery life in a phone depends heavily on the manufacturer’s software tuning, display, and battery size.
