On November 6, MediaTek officially released a new generation of flagship 5G generative AI mobile chip Tianji 9300.

With its innovative all-core architecture design, the new generation of Tianji 9300 chip provides far more thermal features such as high intelligence, high performance, high energy efficiency and low power consumption than ever before, and redefines the flagship mobile experience in end-to-side generation AI, games, imaging and other aspects through breakthrough advanced technological innovation.

After the launch of Tianji 9300, it has aroused a heated discussion among technology enthusiasts and even the whole industry, and the focus is on the fake excellent performance and amazing energy efficiency performance of the innovative all-large-core chip architecture.

Of course, there is also its excellent game, AI, video, connection and other aspects of innovation, also attract attention.

Today, let's have an in-depth discussion around these topics.

What is the mystery of the groundbreaking CPU all-core architecture? As we all know, the most interesting point of Tianji 9300 flagship chip is the use of innovative CPU core architecture design.

Specifically, it contains four Cortex-X4 super-large cores with the highest frequency up to 3.25GHz, and four Cortex-A720 large cores with the main frequency of 2.0GHz. Its peak performance is 40% higher than that of the previous generation, and the power consumption is reduced by 33%.

The most intuitive benefit of the all-core CPU architecture is, of course, higher performance. Tianji 9300 ranks first in the industry, with a comprehensive running score of more than 2130000 in the room temperature environment and more than 2200000 in the laboratory environment.

At the same time, in GeekBench 6, the score of single core is 2203, while that of multi-core is 7616, which is also the first in the industry.

At the same time, it is worth mentioning that the Tianji 9300 was the first to support LPDDR5T 9600Mbps memory, which is also a great help to the performance experience in the actual experience.

The performance gain of the all-core architecture is evident. The key to this performance gain is the improvement of parallel computing power under multithreading. It can systematically identify important tasks and reduce the waiting time. At the same time, more large cores also have stronger computing power to meet the computing needs when resources are crowded.

For example, Tianji 9300 can keep the game running at full frame for 30 minutes in the scenario of extremely high-quality 60FPS + double-open and reload of Wechat video calls, increasing the average frame rate by 15.5% and reducing average power consumption by 12.3% compared with the traditional architecture.

From this, it shows that the Tianji 9300 all-core CPU architecture takes the lead in performance release.

Compared with the powerful performance, I believe more friends are concerned about how Tianji 9300 should not only have a full-core CPU architecture, but also ensure energy efficiency? As mentioned earlier, its power consumption is 33% lower than that of the previous generation. What technologies have they used and what efforts have they made?

First of all, it is natural that TSMC's third-generation 4nm technology is becoming more and more proficient. At the same time, MediaTek, as the third largest customer of TSMC in the world, has a very deep cooperation with TSMC. It also has a special adjustment with TSMC in terms of performance and efficiency of TSMC 9300, which is half a generation to one generation ahead of its competitors.

Secondly, MediaTek fully uses the kernel of out-of-order execution (out-of-order) in the Tianji 9300 platform. Disorderly execution, for example, a company has a lot of order tasks, sequential execution, each employee needs to wait for an employee to give him the handover task, there is no handover can only wait, and disorderly execution at this time the employee can do other tasks, wait for an employee to hand over the task, and continue to do this task.

Therefore, out-of-order execution significantly improves the efficiency of application execution, reduces the occurrence of stutter in the process of operation, and reduces power consumption by doing and resting quickly.

There is a reason why MediaTek chose to do so. Now that the chip process has been advanced to 4nm, the more advanced the process, the more difficult it is to control transistor leakage, so power consumption is inevitable no matter how small the core is. Instead of spending a long time with a small core, use a big core to solve the task quickly, and then go to bed early.

This is actually a bold and advanced idea, and the key to it is Zhang Genghao, director of product planning of MediaTek's wireless communications division. In the interview, Zhang Genghao used the military as an analogy:

"you need to know which enemy you want to kill first, and the second is to wipe out the enemy quickly. so what we can do is to define some procedures that know the key, and then quickly solve it, and then the army will go back to rest."

Third, under the all-core architecture, the invocation mechanism of App performance resources at the bottom of the Android platform has also changed, so if you want to really reduce power consumption, a more important task is to lead the whole ecology to adapt.

MediaTek has also given full consideration to this point and will mainly promote the entire ecological chain to adapt the CPU architecture of the whole core from three directions:

MediaTek will continue to adjust and optimize the performance of Tianji 9000, 9200 and 9300.

At the same time, MediaTek will actively cooperate with terminal manufacturers and software application vendors to let ecological partners know what the characteristics are under the large-scale core architecture, and tune with their OS and important App.

Finally, MediaTek is also working with upstream Google to tune the eight-core architecture at the Android AOSP level and in Google Service.

To sum up, it can be seen that the full-core CPU architecture of Tianji 9300 is not only as simple as replacing all the cores with large cores, but also difficult to schedule the performance and optimize the power consumption after the full-core. As Zhang Genghao said in the interview:

"the design of the software, the design of the system, how to find some key scenarios, how to optimize it, how to gather all the applications together, can quickly finish it, quickly and deeply sleep, and can save electricity when you sleep."

To do this, it must be strung together from end to end, from hardware to software to the system. These are not only challenges, but also demonstrate MediaTek's courage to move resolutely towards an innovative no man's land.

In addition to the all-core CPU architecture, Tianji 9300 is also wonderful in addition to the unprecedented all-core architecture CPU, Tianji 9300 also has a breakthrough in other aspects of innovative technology, which can bring industry-leading experience in games, AI, video, and so on. Let's move on.

GPU and game experience are games first. Tianji 9300 is the first to adopt the new generation of flagship 12-core GPU Immortalis-G720. Compared with the previous generation, the peak performance is improved by 46%, and the power consumption is reduced by 40% under the same performance. It can bring a lasting and smooth flagship mobile game experience.

For example, using Tianji 9300 to run "original God" in extremely high definition and playing for 30 minutes in the overloaded Sumicheng scene can achieve full frame running, and the average power consumption can be reduced by-20% compared with the previous generation. The speed of entering the game is increased by 11.5 seconds and the transition speed is increased by 25%.

On the other hand, it can run in full frame for 30 minutes in very high-quality mode of "collapse: star Dome Railway".

At the same time, the Tianji 9300 is also equipped with MediaTek's second-generation hardware ray tracing engine, which supports high fluency ray tracing of 60FPS and brings host-level global lighting effects. So as to make our game picture quality more realistic, more natural, and bring a great improvement of visual experience. Not only that, Tianji 9300 also through in-depth optimization, while achieving global lighting, but also achieve fluency and power saving.

To achieve global illumination on the mobile side, not only according to the light changes to simulate the human eye response for real-time fast rendering, but also to consider the needs of multi-light source scene, there should be enough computing power to support.

Tianji 9300 benefits from the improvement in the computing power and energy efficiency of Immortalis-G720, which helps mobile light pursuit, while deeply cooperating with the game engine Vulkan Ray Query to provide the best guidance for developers, and they are also working with Tencent and ARM to help Intelligent Global Illumination (SmartGI) as an industry standard, and first released on GDC 2023, so that the global illumination algorithm is supported by hardware light pursuit, so that memory can be reduced by 30%. Rendering pipeline optimization reduces the length of time by 45%, etc.

Various optimizations make it possible to strike a balance between high picture quality and low power consumption, really opening up the global illumination era of the mobile terminal.

In addition, on the Tianji 9300, the original MAGT game adaptive control technology unique to MediaTek was upgraded to "Star engine", which will not only cooperate widely with game applications, but also expand ecological cooperation among more types of applications and continuously enhance the game experience.

AI experience on the AI side, the Tianji 9300 integrates MediaTek's seventh generation AI processor APU 790, designed for generative AI, with significantly improved performance and energy efficiency, twice the performance of the previous generation of integer and floating-point operations, and a 45% reduction in power consumption.

At the same time, the new APU 790s have a built-in hardware-level generative AI engine to achieve more high-speed and secure edge AI computing, depth adaptation to the Transformer model for operator acceleration, processing speed is 8 times that of the previous generation, and images can be generated in 1 second.

APU 790also supports mixed precision INT4 quantization technology, combined with MediaTek's unique memory hardware compression technology NeuroPilot Compression, which can make more efficient use of memory bandwidth and greatly reduce the terminal memory footprint of the AI large model, thus enabling the terminal to run the AI large language model with 1 billion, 7 billion, 13 billion and up to 33 billion parameters.

APU 790also supports generative AI model end-to-side "skill expansion" technology NeuroPilot Fusion, which can continuously carry out low-rank adaptive (LoRA,Low-Rank Adaptation) fusion on the end-side based on the basic large model, thus giving the basic large model more comprehensive capabilities.

In addition, MediaTek's AI development platform NeuroPilot has also built a rich AI ecology, supporting cutting-edge mainstream AI models such as Meta LIama 2, Baidu Wenxin big model, Baichuan intelligent Baichuan big model and so on. A complete tool chain can help developers deploy multimodal generated AI applications quickly and efficiently at the end-side, providing users with terminal-side generative AI innovation experiences such as text, images, music, etc.

In terms of image experience, Tianji 9300 is equipped with the flagship ISP image processor Imagiq 990. it supports AI semantic segmentation video engine, which can perform 16-layer image semantic segmentation, and optimize the color, texture, noise and brightness of the captured picture frame by frame in real time, thus making the recorded video picture brighter, sharper and richer in detail.

At the same time, with the upgrading of the dual engines of depth of field and spot, Tianji 9300 can show a film-level light and shadow effect when recording 4K video.

Tianji 9300 also integrates OIS optical anti-shake core, which can significantly improve the anti-shake operation speed and film rate, and can quickly capture high-definition images in moving scenes and dark light environments.

In addition, the chip also supports full-pixel focus superimposed 2x lossless zoom, that is, 2 zoom shots without the need for an optical zoom lens, which is the result of close cooperation with the world's leading sensor manufacturers. can bring users a more professional mobile image experience.

Other innovative experiences in other experiences, Tianji 9300 also has a very versatile performance, for example, in display, Tianji 9300 integrates MiraVision 990mobile display processor, supports 180Hz WQHD and 120Hz 4K display, and dual-screen display of terminal devices in the form of a folding screen.

At the same time, it also has a flagship intelligent TV class AI depth-of-field image quality engine, combined with the powerful AI performance of APU 790s, it can detect major objects and background images in real time. With MiraVision PQ image quality enhancement technology, it can dynamically adjust the contrast, sharpness and color of major objects, enhance the three-dimensional sense of the overall image, and make the picture more lifelike.

In terms of connection, Tianji 9300 supports Wi-Fi 7, the highest theoretical peak rate can reach 6.5Gbps, with MediaTek Xtra Range ™2.0 technology, Wi-Fi 7 indoor coverage can be increased by 4.5m, and Tianji 9300 can support up to three Bluetooth antennas, unique two-way Bluetooth flash technology, bringing ultra-low latency Bluetooth audio experience.

At the same time, it also integrates 5G modems, supports Sub-6GHz four-carrier aggregation (4CC-CA) and multi-standard dual-card dual access, uses MediaTek 5G UltraSave 3.0 + power-saving technology, greatly reduces 5G communication power consumption, and integrates 5G with AI, bringing context-aware functions.

In addition, in terms of audio, Tianji 9300 supports three microphones for high dynamic recording noise reduction, with omni-directional high dynamic radio capability and advanced noise separation technology, it can effectively filter ambient noise such as wind noise and provide users with a purer HDR stereo recording experience.

Finally, in the aspect of data security, Tianji 9300 integrates double security chips, and the special security chip adopts advanced user data security design, which can protect personal privacy from the boot source and has a physically isolated computing environment. At the same time, MediaTek also uses advanced memory tag extension (MTE) technology to create a more secure application development environment and build a more powerful user data security.

Tianji 9300, as a whole, the new generation of Tianji 9300 flagship platform is a special product not only for MediaTek, but also for the whole mobile chip and terminal industry.

First of all, with the advancement of the intelligent and mobile process, the demand for computing power of intelligent terminals is increasing rapidly, and there are more and more scenarios of multi-task parallelism. Under this trend, the full-scale core architecture can be said to be the inevitable trend of the whole mobile chip industry in the future. In fact, Apple, which is also a leader in the field of mobile chips, is also exploring the direction of a full-core architecture. For example, the performance core frequency of the A17 Pro can reach 3.78GHz, and although the energy efficiency core is "energy efficiency", the frequency can also reach 2.11GHz, in fact, it is also a "big core". The release of the Tianji 9300 platform means that MediaTek has taken the lead in the "full core" step in the Android field, which has cut into the new track in advance with a forward-looking layout and gained the advantage of a forerunner. at the same time, it also played a leading role in the whole industry. It is believed that in the future, other mobile chip suppliers in the industry will continue to follow the overall core architecture.

Secondly, as mentioned earlier, the full-core CPU architecture will also bring innovation opportunities to the underlying software experience of Android. Under the background that advanced processes bring more and more limited gains to chip performance and energy efficiency, promoting the logic and strategy of the underlying hardware and software combined with resource scheduling through the full-core architecture to a more efficient and reasonable state is obviously of great significance to the improvement of Android ecological experience in the future. At the same time, for users, this is naturally a favorite thing to hear and see.

Moreover, for the smartphone industry, the flagship mobile phone market is now experiencing performance bottlenecks. Terminal brands have been relying on volume parameters and crazy heaps to force the performance and experience of terminals for a long time, but this cannot be sustained for a long time. The launch of Tianji 9300 and the landing of the all-core CPU architecture will undoubtedly lead smartphones to break through the bottleneck of performance and experience through long-lost underlying innovation, and pave the way for the mobile phone industry to enter a new stage of development.

Finally, from the perspective of the industry pattern, Tianji flagship platform after three generations of development, is constantly changing the competitive pattern of the flagship mobile phone chip market. With the blessing of breakthrough architectural innovation, Tianji 9300 is expected to complete the decisive blow of the "game changer" and really open up a new pattern of the flagship mobile chip market. Since then, it is believed that MediaTek will have the strength and strength to compete with the previous hegemons in the flagship chip market.

Conclusion in the development of chip semiconductors, performance and energy efficiency are eternal topics, and it seems to be a contradiction that is difficult to have at the same time. In the past years, the industry has made a lot of efforts to "improve performance and reduce power consumption".

The all-big core architecture of Tianji 9300 can undoubtedly represent the latest achievements explored by the industry in this direction. while greatly improving the performance of the chip, it also overcomes many challenges at the technical and industrial level with brand-new ideas. so that the overall energy efficiency of the system has also been leapfrog, achieving a seemingly impossible balance.

It is believed that under the guidance of Tianji 9300, the trend of large-scale nuclear architecture will gradually start a prairie fire, thus enabling smart terminals to enter a new era of performance and energy efficiency experience.

Of course, at present, it is only the beginning of the journey, the improvement of technology, ecological groundwork, MediaTek and all partners to promote. We also look forward to a faster and smoother response to all this, so that consumers can enjoy the "performance free" mobile terminal experience as soon as possible.
