Qualcomm Snapdragon 8 Gen 3 vs MediaTek Dimensity 8300-Ultra - flagship or fast sub-flagship without overpayment

Snapdragon 8 Gen 3 - the top platform for expensive Android flagships.
Dimensity 8300-Ultra - a powerful sub-flagship chip that is more commonly found in more affordable Xiaomi and POCO smartphones.

It's important to understand: the Ultra designation does not turn the Dimensity 8300-Ultra into a full-fledged competitor to the Snapdragon 8 Gen 3. This is a version of Dimensity 8300 for Xiaomi, POCO, and Redmi devices with a proprietary platform configuration, but it still belongs to the upper mid-range class.

The main question here is not which processor is more powerful. Snapdragon 8 Gen 3 is more powerful. It is more important to understand whether it is worth paying extra for flagship reserve if the Dimensity 8300-Ultra already covers most real scenarios.

Quick Summary

Snapdragon 8 Gen 3 is the choice if heavy games, high FPS, a strong camera, advanced modem, Wi-Fi 7, fast on-device AI, and performance reserve for several years are important.

Dimensity 8300-Ultra is more cost-effective if you need a very fast smartphone for applications, gaming, photo, video, and everyday use, but without overpaying for a true flagship.

In simple terms: Snapdragon 8 Gen 3 - maximum capabilities, Dimensity 8300-Ultra - almost flagship speed for more reasonable money.

Main Differences

Performance

Snapdragon 8 Gen 3 is faster in almost everything. It features a powerful main Cortex-X4 core, a strong cluster of performance cores, and a high reserve for heavy tasks: gaming, photo processing, video editing, emulators, AI functions, and multitasking.

Dimensity 8300-Ultra is weaker, but it is by no means a slow chip. In regular use, the difference is often imperceptible: the interface, browser, social media, messengers, camera, and most applications work quickly. For most users, its performance is more than adequate.

The difference becomes more pronounced under prolonged load. Snapdragon 8 Gen 3 is better suited for scenarios that require maintaining high speed for extended periods: heavy gaming, video recording, processing large files, emulators, and active multitasking. Dimensity 8300-Ultra is also fast, but it often depends more on cooling and the specific smartphone settings.

Gaming and Graphics

In gaming, the advantage of Snapdragon 8 Gen 3 is more noticeable than in regular tasks. The Adreno 750 graphics are more powerful than the Mali-G615 MC6, making it better suited for high settings, stable FPS, and heavy gaming projects.

In demanding games like Genshin Impact, Honkai: Star Rail, and Wuthering Waves, Snapdragon 8 Gen 3 often allows for playing at higher settings and maintaining stable frame rates for longer. This is especially apparent in gaming smartphones or flagships with good cooling systems.

Dimensity 8300-Ultra is also suitable for gaming. The POCO X6 Pro demonstrates that this chip can deliver very good performance for its price: it handles modern games, opens applications quickly, and feels significantly more powerful than typical mid-range platforms. However, it is not on the level of gaming flagships: in the heaviest projects, settings may sometimes need to be lowered, and FPS stability will rely more on the casing and cooling system.

A separate advantage of Snapdragon is the Adreno graphics drivers. They often perform better in emulators and some games with Vulkan, where optimization for Qualcomm can provide a noticeable advantage.

Energy Efficiency and Heat

Both chips are manufactured on a modern 4nm process technology, but the final performance depends not only on the processor. Factors like the casing, cooling system, battery, display, and manufacturer settings are crucial.

For prolonged heavy gaming, it is better to choose a smartphone with Snapdragon 8 Gen 3 and a good cooling system. For everyday use, social media, browsing, video, and occasional gaming, Dimensity 8300-Ultra appears very rational.

Camera and Video

Snapdragon 8 Gen 3 excels in camera and video capabilities. Its 18-bit ISP is designed for flagship scenarios: complex HDR processing, multi-camera systems, high video quality, and advanced image processing algorithms.

However, it’s important not to overestimate the chip itself. The camera is influenced not only by the chip but by the entire smartphone: sensor, optics, stabilization, processing algorithms, and manufacturer settings. Snapdragon 8 Gen 3 is often found in more expensive models, so users typically also receive a stronger camera module with it.

Dimensity 8300-Ultra also supports good camera and video capabilities. For example, the Xiaomi 14T on this chip puts greater emphasis on the camera, display, and overall user experience compared to the POCO X6 Pro. Nevertheless, on average, smartphones with Dimensity 8300-Ultra still tend to belong to the "almost flagship" class rather than true camera phones.

The verdict is simple: if superior video recording, complex HDR processing, and flagship-level cameras are important, Snapdragon 8 Gen 3 is preferred. If decent everyday shooting is sufficient, Dimensity 8300-Ultra will do just fine.

Connectivity and Wireless Capabilities

Snapdragon 8 Gen 3 is stronger in communications. The Snapdragon X75 modem, support for Wi-Fi 7, and greater reserve in networking capabilities make it better for expensive smartphones that are purchased for several years.

Dimensity 8300-Ultra offers modern 5G, Wi-Fi 6E, and Bluetooth 5.4 depending on the specific device. For most users, this is adequate: messengers, video, gaming, navigation, and mobile internet will work quickly.

The difference is more important for those who want maximum future-proofing, Wi-Fi 7, a more advanced modem, and better connectivity in a premium smartphone.

Artificial Intelligence and NPU

Snapdragon 8 Gen 3 is better prepared for heavy on-device AI scenarios: generative features, image processing, local language models, and advanced AI tools in the camera.

Dimensity 8300-Ultra with MediaTek APU/NPU 780 is also designed for modern AI tasks, including generative functions, photo enhancement, scene recognition, noise reduction, and voice capabilities. However, in terms of capacity for heavy local AI, Snapdragon 8 Gen 3 appears stronger.

At the same time, comparing NPUs directly by TOPS is not always correct: manufacturers use different metrics, types of computations, and testing scenarios. For users, the important aspect is not just a dry number but what AI functions are actually available in the specific smartphone.

Examples of Smartphones

Smartphones with Snapdragon 8 Gen 3

Samsung Galaxy S24 Ultra - one of the most well-known flagships with Snapdragon 8 Gen 3. This is a device where the powerful chip is complemented by a strong camera, quality display, S Pen, good battery life, and long-term support.
