MediaTek releases Dimensity 9300 flagship 5G AI mobile chip

MediaTek recently released the Dimensity 9300 flagship 5G generative AI mobile chip, and the first smartphone equipped with the chip is expected to be launched by the end of 2023

MediaTek Director and General Manager Chen Guanzhou said: "With the advent of the era of comprehensive intelligence, MediaTek has achieved success in many fields such as smart terminals, smart cars, and smart homes by virtue of its deep foundation and rich experience in the field of edge computing. Diversified development and achieved outstanding results. Through our leading edge AI computing and hybrid AI computing technology, we are committed to building a new full-scenario intelligent experience for users, promoting the popularization of generative AI innovative applications, and allowing cutting-edge technology to benefit a wider range of people. The masses empower thousands of industries.”

Xu Jingquan, senior deputy general manager and general manager of the wireless communications business unit of MediaTek, said: "Dimensity 9300 is MediaTek's most powerful flagship mobile chip to date. Through our groundbreaking full-core architecture design, Bringing amazing computing power breakthroughs to flagship smartphones, the unique full-core central processing unit (CPU) combines a new generation of application processor unit (APU), graphics processing unit (GPU), and image signal processor (ISP). And MediaTek’s unique cutting-edge technology can not only significantly improve terminal performance and energy efficiency, but also bring consumers an excellent end-side generated artificial intelligence (AI) experience.”

According to reports, in order to meet the increasing demand for mobile computing power in modern and future times, MediaTek jumped out of traditional architectural design thinking and pioneered the "all-large-core" CPU architecture of the Dimensity 9300, including 4 Cortex-X4 ultra-large cores , with a maximum frequency of 3.25GHz and 4 Cortex-A720 large cores with a main frequency of 2.0GHz. Its peak performance is 40% higher than the previous generation and power consumption is saved by 33%.

Dimensity 9300 is equipped with MediaTek’s seventh-generation AI processor APU 790. Its integer operation and floating-point operation performance is twice that of the previous generation, and its power consumption is reduced by 45%. APU 790 has a built-in hardware-level generative AI engine, which can achieve faster and safer edge AI calculations, and perform operator acceleration through deep adaptation of the Transformer model. The processing speed is 8 times that of the previous generation, and can be generated in 1 second. picture. Based on the characteristics of large language models with billions of parameters, MediaTek has developed mixed-precision INT4 quantization technology, combined with MediaTek's unique memory hardware compression technology NeuroPilot Compression, which can more efficiently utilize memory bandwidth and significantly reduce the occupation of terminal memory by large AI models. , supporting terminals to run AI large language models with 1 billion, 7 billion, 13 billion, or even up to 33 billion parameters

APU 790 also supports the generative AI model end-side "skill expansion" technology NeuroPilot Fusion, which can continuously perform low-rank adaptation (LoRA, Low-Rank Adaptation) fusion on the end-side based on the basic large model, thereby empowering the basic large model More comprehensive capabilities.

In addition, Dimensity 9300 is the first to adopt the new generation flagship 12-core GPU Immortalis-G720. Compared with the previous generation, the peak performance is increased by 46% and the power consumption is saved by 40% under the same performance. Dimensity 9300 is equipped with MediaTek’s second-generation hardware ray tracing engine, which supports 60FPS high-smooth ray tracing and brings game console-level global illumination effects. In addition, MediaTek's unique MAGT game adaptive control technology has been upgraded to "Star Speed ​​Engine", which not only cooperates extensively with game applications, but also expands ecological cooperation with more types of applications to continue to improve user experience

Dimensity 9300 is reported to have the flagship ISP image processor Imagiq 990, which supports AI semantic segmentation video engine. This chip has 16 layers of image semantic segmentation capabilities, which can optimize the color, texture, noise and brightness of the picture frame by frame in real time, making the recorded video picture brighter, sharper and richer in detail. With the upgrade of the depth of field and light spot dual engines, the Dimensity 9300 can present movie-level light and shadow effects in 4K video recording. In addition, the chip also integrates an OIS optical anti-shake core, which can significantly improve the anti-shake calculation speed and film yield, and can quickly capture high-definition images in sports scenes and dark light environments. At the same time, Dimensity 9300 also supports full-pixel focus and superimposed 2x lossless zoom function
