The hardware gap in devices has made the PC side occupy a large market of players who demand a sense of game quality and experience, and now, with mobile support for ray tracing technology, handheld gamers can finally raise their eyebrows a bit. MediaTek's breakthrough in the field of mobile graphics technology is bringing an unprecedented reform to the ever-changing gaming market.

The performance of the GPU determines the upper limit of the graphics rendering capability of the mobile chip, and is the key to enhancing the mobile gaming experience. MediaTek's Tiangui 9200 mobile chip is the first to be equipped with the new generation Arm Immortalis-G715 flagship 11-core GPU, bringing up to 32% performance improvement and a significant 41% reduction in power consumption, providing core power for sustained high graphics quality and high frame rate for mobile games.

Dr. Jingquan Xu, MediaTek's Vice President and General Manager of Wireless Communication Business Unit, had said at the launch of the Tiangui 9200: "Our debut of the top GPU Immortalis-G715 with Arm's latest architecture is the result of our deep collaboration with Arm over the years, and in addition to optimizing the GPU architecture, we have also worked with Arm to create advanced features for flagship mobile devices - hardware ray tracing and variable rate rendering technology for mobile."

　　Hardware ray tracing technology that will revolutionize mobile graphics development

The Immortalis-G715 GPU in the Tiangui 9200 supports hardware ray tracing technology for mobile, which can bring physical lighting effects comparable to the real world to mobile games and help gamers enjoy an immersive visual experience. Ray Tracing is a hot graphics rendering technology for PC in recent years. Unlike traditional Rasterization technology, ray tracing simulates the physical behavior of light to build virtual scenes and optimize reflections, shadows, and other image effects so that virtual 3D scenes present more realistic lighting effects, material textures, and object position relationship and other information. For example, in the game, the shadow of the protagonist is mapped onto the old building, and through ray tracing technology on the mobile side, players can more clearly predict the distance between the two, and even see the approaching enemies from the reflective porcelain tiles in the broken walls. It is not difficult to foresee that the migration of ray tracing technology to the mobile side is an effective way to continuously improve the picture quality of mobile devices.

To this end, MediaTek is actively laying out ray tracing technology for mobile and collaborating with industry eco-partners to innovate and explore the path of implementing ray tracing technology for mobile. The Immortalis-G715 GPU on the flagship mobile platform of Tiangui 9200 is the first in the industry to support mobile "hardware" ray tracing.

Based on Immortalis-G715, MediaTek has developed the "three elements" of mobile ray tracing, namely soft shadows, specular reflections and refraction, for the special effects required by game developers and the key visual requirements of gamers for an immersive gaming experience. The three elements of ray tracing are optimized through the computational graphics covered by the Breguet 9200, making the virtual world on mobile devices look less "fake" and bringing changes to mobile graphics development from the chip layer.

Light tracing soft shadows: Real-world shadows have different softness and hardness depending on the distance to the light source or the intensity of the light. Traditional rendering methods can only achieve hardened shadows that are out of place in the surrounding environment. MediaTek relies on mobile ray tracing technology to calculate the reflection angle and position corresponding to the scene object relatively realistically, thus forming a more realistic soft shadow that reflects the light intensity and different distances.

Ray tracing specular reflection: Compared with traditional rendering methods, mobile ray tracing technology can more realistically calculate the angle and position of the corresponding specular reflections of different objects in the scene, thus providing a more realistic vision in line with the habits of the human eye. For example, on a smooth ground, the technology can clearly reflect the objects in the scene, and reflect the reflection with different strengths and weaknesses depending on the intensity of the light source. At the same time, the material and texture of the ground is also obvious because of the reflected light, making the whole picture more spatially three-dimensional.

Ray-tracing refraction of glass objects: belongs to a special and complex visual effect, and the refraction presents a very different picture on objects of different materials. In order to save arithmetic power, the traditional graphics rendering method does not deliberately draw the changes of refracted light, through the mobile ray tracing refraction rendering technology, can add different angles of refraction details to the screen, more realistic restoration of physical phenomena, enhance the player's immersive game realism.

In addition to the above "three elements", through the mobile ray tracing technology, MediaTek optimized for ambient light, can achieve the ambient light masking effect. Through the ambient light masking technology, the indirect light source to enhance the processing of shadows and other dark areas, so that the dark picture more detailed, enhance the sense of the scene layers.

MediaTek has been committed to the innovative research and development of mobile graphics technology, and as an important promoter of ray tracing on mobile, MediaTek has worked closely with the production team of Tencent's Dark Zone Breakout game. Both parties have laid out and collaborated early to develop the application of ray tracing technology on mobile for the game, from game engine optimization and pipeline optimization to the presentation of light tracing content effects, through the in-depth cooperation and meticulous polishing of both parties, the application of ray tracing technology on the Tiangui Through in-depth cooperation and meticulous polishing, the two companies have demonstrated excellent results on the 9200, creating amazingly realistic picture quality in shadows, reflections, ambient light masking and other game effects, bringing players an immersive visual experience and accelerating the commercialization of ray tracing technology for mobile games.

In the practical application of "Dark Zone Breakout" game, the outdoor ray tracing shadows can simulate the real sunlight shadows, with sharp shadows in the near area and soft shadows in the far area. The ray tracing-based ambient light shading can reflect the diffuse light shading effect between intersecting objects, which in turn emphasizes the relationship between the placement of objects and makes the picture more layered. Compared with the traditional ambient light masking technology, ray tracing-based ambient light masking can more accurately reflect the ambient light masking relationship between objects and avoid black halo and other phenomena in the traditional technology because it can obtain accurate scene information. It better optimizes the player's sense of real experience in the game map. The quality of natural light is highly restored to provide players with a more immersive sense of the battlefield.

In the reflection of environmental objects, the smooth surface can present a clear and accurate reflection of the scene, increasing the realism and immersion of the scene. Compared to traditional reflections, ray-tracing-based reflections can render objects outside the viewpoint that players cannot directly see, such as behind them and behind the sides of walls. Based on ray tracing reflection technology, players can get richer and more realistic battle information through the environment within the battlefield confrontation, which will greatly improve the game's gameplay and confrontation, and also provide players with a richer tactical space.

Based on the powerful GPU capability of the Tiangui 9200 chip, combined with the HyperEngine 6.0 game engine, MediaTek has pushed the mobile gaming graphics to a new level, bringing players a more realistic immersive sensory experience.

Game adaptive control technology, full frame, low power consumption to empower the flagship core experience

Along with the release of the Tiangui 9200, MediaTek also released a new game adaptive control technology (MediaTek Adaptive Game Technology, or MAGT), which can reduce the power consumption of high frame rate games and the temperature of the terminal device, making full frame operation more durable. As the first strategic partner of this technology, the two teams have explored and built the advanced technology of terminal device and game adaption. Through the efficient MAGT architecture, the Glory of Kings system can dynamically adjust the rendering logic of the game according to the real-time load of the terminal hardware, bringing a better experience of extreme image quality at full frame and stable frame, and making the game last longer.

Whether it's a hero skill performed in a sudden melee, or a sneak attack between the grass, or even the sparkling water, MAGT's architecture always allows the game application to work hand in hand with the platform to support the core gaming experience such as stable frame rate and long-lasting game life behind the player.

Using MAGT's architecture, "King of Glory" 5V5 ranking on the Tiangui 9200 full frame running temperature difference is reduced by up to 4 degrees Celsius, while power consumption is reduced by 18.8%, significantly improving the low temperature and lasting excellent gaming experience!

Cold power full speed, full frame low power consumption is the common goal of MediaTek and "glory of the king". In the future, MediaTek will continue to explore new technologies and new ways to provide summoners with a better quality and smoother gaming experience.

In addition, the 9200 also supports Variable Rate Rendering (VRS) technology, which dynamically adjusts the rendering multiplier for different visual areas to achieve improved performance or reduced power consumption based on developer optimization tuning, which is a notable feature of the GPU in the 9200, bringing a significant increase in game frame rate.

The HyperEngine 6.0 gaming engine of the 9200 is equipped with Intelligent Frame Stabilization Technology 2.0, which can more accurately and quickly monitor the system state and the phone's heat state, and decide the scheduling of system modules based on temperature prediction. Compared with the previous generation flagship chip of Tenguiz, the average frame rate of Tenguiz 9200 can be increased by 15% and the frame rate jitter rate reduced by 63% when running for 30 minutes in "Original God" at 60FPS very high picture quality and 5G connectivity mode.

See clearly to hit accurately. HyperEngine 6.0 game engine supports pixel-level real-time trailing shadow elimination, which dynamically improves trailing shadows in the game screen frame by frame by accelerating pixel display, making the game screen clearer and allowing players to see every screen in the game more " clean and crisp".

MediaTek continues to devote itself to technology research and development in the field of graphics, and will continue to expand the key technologies of MediaTek HyperEngine game engine to bring end-game level game rendering effects to mobile terminals, providing powerful graphics processing capabilities and solutions for game manufacturers, developers, and terminal manufacturers, bringing realistic game graphics to the majority of gamers, and leading the development trend of mobile graphics through long-term investment in advanced technologies and open We will lead the development trend of mobile graphics through long-term investment in advanced technology and open cooperation.
