Experience the Revolutionary Technology of Tianji 9300 A Pre-Test on How Full Big Core Architecture Revolutionizes Mobile Phones

Currently, our daily lives are inseparable from the help of smartphones. Therefore, when many users are choosing a phone, they will choose flagship models that provide a smoother user experience. This “smooth experience” is inseparable from the powerful computing power provided by the hardware, which is also supported by the powerful performance provided by flagship-level chips.

Dimensity 9300

By the end of 2023, MediaTek has brought consumers a more advanced flagship platform – Dimensity 9300. This chip breaks through traditional architecture design thinking and adopts a “full large-core” CPU architecture with 4 ultra-large cores + 4 large cores, which comprehensively improves chip performance and brings users a smooth usage experience.

Prior to the launch of the terminal equipped with Dimensity 9300, PhoneAuto got hold of the engineering machine of Dimensity 9300 in advance and also experienced the “full large-core” architecture, which enhances the user experience.

In order to balance “high performance” and “low power consumption,” smartphone chips often adopt a “big core + small core” architecture design. When faced with complex computational needs, the big cores will run at full capacity and efficiently complete tasks. When faced with simple and light tasks, the small core can easily handle them, thus meeting lightweight demands with lower power consumption. However, as chip performance continues to improve, user demands are also constantly changing. We often perform multiple tasks on one device simultaneously. At this time, the traditional small core cannot handle complex tasks, but calling upon the big core or ultra-large core will also result in higher energy consumption.

Dimensity 9300

Can we ensure smooth multitasking with lower power consumption? The full large-core CPU architecture of Dimensity 9300 is a completely new approach. The “full large-core CPU architecture” includes 4 Cortex-X4 ultra-large cores with a maximum frequency of 3.25GHz, as well as 4 Cortex-A720 large cores with a frequency of 2.0GHz. When running light-load applications, the large cores can complete computing tasks faster and quickly return to idle state, thereby controlling power consumption. When running heavy-load applications, the higher-frequency large cores and ultra-large cores can also unleash their full power.

Dimensity 9300 adopts TSMC’s third-generation 4nm process, which is at the forefront of the industry. Combined with the full large-core CPU architecture, official data shows a 40% increase in peak performance and a 33% reduction in power consumption compared to the previous generation.

Dimensity 9300 Engineering Machine scored 2,148,858 points in AnTuTu

The Dimensity 9300 engineering machine achieved a GeekBench single-core score of 2209 and a multi-core score of 7583.

After testing, the engineering machine with the built-in Dimensity 9300 achieved a score of 2148858 in the AnTuTu project, placing its overall performance in the top tier of the current Android camp. In the GeekBench test, the Dimensity 9300 also achieved a single-core score of 2209 and a multi-core score of 7583, showing significant improvement compared to the previous generation Dimensity 9200. It directly takes the lead in multi-core performance as well.

For mobile chips, the “full big-core CPU architecture” is a new innovation. MediaTek’s choice to adopt a full big-core design at the CPU level also takes into consideration better CPU universality. With the switch to a full big-core architecture, developers do not need to carry out specific adaptations; conversely, even applications with lower performance can make use of the stronger computational power advantage of big cores to complete calculations more efficiently. To put it simply, the CPU is like “solving math problems.” You can think of “small cores” as elementary school students, who may not calculate as quickly but consume less energy, while “big cores” are more like middle school students, who calculate faster but consume slightly more energy. Faced with the same amount of “math problems,” big cores, similar to middle school students, can compute more quickly and rest afterwards, while small cores, like elementary school students, take longer to compute and require more power to complete the operation.

The Dimensity 9300 precisely leverages the advantage of “calculating quickly and resting immediately” to achieve more efficient processing capability than small cores, while still maintaining low power consumption.

The normalized CPU utilization rate of the Dimensity 9300 is approximately 24%.

Through the full big-core design, the Dimensity 9300 can efficiently handle a series of small to medium-sized tasks using its four big cores. Thanks to the powerful performance provided by the big cores, the Dimensity 9300 can also maintain a more reasonable CPU utilization rate while running high-load games, thereby controlling the overall heat generation of the device. Taking “Genshin Impact” as an example, you can see that the normalized CPU utilization rate of the Dimensity 9300 does not exceed 30% and averages at around 24%. This means that during game operation, the CPU spends only about 24% of its time processing data. This efficient data processing capability reduces CPU usage time, thereby controlling power consumption and heat generation, which is an advantage brought by the full big-core architecture.

Additionally, another significant advantage of the full big-core architecture is its stronger ability to handle parallel multitasking. In the current development of smartphones, foldable screens, pads, and other large-screen devices have become the new direction of the industry. These large-screen devices require stronger multitasking capabilities, and this is where the full big-core architecture of the Dimensity 9300 can truly shine.

While experiencing the engineering version of Dimensity 9300, I also tested the performance of “playing games + video calling” simultaneously. This is a moment that many users have experienced, and it is a heavy usage scenario. The full big core architecture of Dimensity 9300 can provide high-quality Genshin Impact gameplay at full frame rate and stable video calling effects at the same time. Additionally, the device keeps its temperature under control quite reasonably. Now that Dimensity 9300 has provided sufficient foundation, we look forward to major terminal manufacturers making good use of this powerful chip to create a smoother user experience.

While leading the industry in CPU architecture, Dimensity 9300 also continues its powerful GPU and AI computing capabilities. This time, Dimensity 9300 is equipped with the new generation flagship 12-core GPU, Immortalis-G720. Compared to the previous generation, it offers a 46% increase in peak performance and 40% power savings under the same performance. In simple terms, it delivers stronger performance and lower power consumption. Additionally, Dimensity 9300 continues to feature hardware ray tracing technology this year. With the built-in second-generation MediaTek hardware ray tracing engine, it can provide smooth ray tracing at 60FPS, providing a solid foundation for high-quality mobile gaming.

We tested the performance of Immortalis-G720 using GFX Bench. In tests such as Manhattan Offscreen and Aztec Ruins, Dimensity 9300 showed significant improvements compared to the previous generation. Its GPU performance ranks first among flagship chips, which further increases our anticipation for the terminals equipped with Dimensity 9300 and the new enhancements they will bring to the gaming experience.

In today’s industry, large-scale models and generative AI have become hot topics. Dimensity 9300 is also making advancements in the AI field this year. Its integrated MediaTek seventh-generation AI processor APU 790 is designed for generative AI. Its integer and floating-point operation performance is twice that of the previous generation, with a 45% reduction in power consumption. APU 790 also features an integrated hardware-level generative AI engine, enabling faster and more secure edge AI computing.

Dimensity 9300 continues to unlock achievements in large-scale models and becomes the first to bring a 7 billion-parameter AI large language model to vivo flagship smartphones. It has successfully run a 13 billion-parameter AI large language model on the edge and accomplished a groundbreaking feat of running a 33 billion-parameter AI large language model on a mobile chip.

It is worth mentioning that the Tianji 9300 also uses an AI semantic segmentation video engine, achieving up to 16 layers of image segmentation, and is equipped with a top-notch OIS optical anti-shake specialist. In addition, the chip also integrates the MediaTek MiraVision 990 mobile display processor, supporting 180Hz WQHD and 120Hz 4K display. Furthermore, the Tianji 9300 also supports Wi-Fi 7 Enhanced technology, with a maximum theoretical peak rate of 6.5Gbps and an indoor coverage distance increase of 4.5 meters. Finally, the chip also integrates dual security chips, further ensuring the security of personal data encryption and decryption operations.

This time, I also had the opportunity to experience the local AIGC ability of Tianji 9300 up close. Without connecting to the internet, Tianji 9300 can efficiently provide feedback on user-inputted text, enabling functions such as AI drawing and AI-generated articles. And in just 1 second, you can get either an image or a long paragraph of text, smoothly and quickly. MediaTek officials also stated that Tianji 9300 can reduce the memory consumption of AI calculations on mobile phone memory capacity through techniques such as memory hardware compression (NeuroPilot Compression), enabling more efficient local calculations and output of results.

Of course, the on-site demonstration was just a showcase, and how this AI technology will be implemented on every person’s phone depends on the understanding of terminal manufacturers.

By adopting the “all big core” architecture, the Tianji 9300 has brought a new idea to the industry. Despite its powerful performance, it can still balance “high performance” with “low power consumption” through the efficient operation of the big core.

Based on the test results of the Tianji 9300 engineering sample, this chip still exhibits the performance of a first-tier leader, and the efficient operation of the big core also has decent energy efficiency performance even in high-load environments. In today’s world where more and more users are concerned about battery life and whether their phone can last longer, perhaps the appearance of this chip can change our perception of high-performance chips. At the same time, I am also somewhat excited about the vivo X100, which will debut with the Tianji 9300 on November 13th, and I wonder what surprises it will bring us.
