On January 20, MediaTek held an online launch event for the Dimensity series, officially unveiling the new generation flagship 5G chip – Dimensity 1200.Compared to the previous generation Dimensity 1000 series, the new Dimensity 1200 has made significant improvements in CPU/GPU performance, 5G, AI, photography, video, and gaming.
The Dimensity 1200 chip is manufactured using TSMC’s 6nm process, featuring 1 core at 3.0GHz Cortex-A78, 3 cores at 2.6GHz Cortex-A78, and 4 cores at 2.0GHz Cortex-A55, achieving a 22% performance increase and a 25% improvement in energy efficiency. The GPU scale remains largely unchanged, with a maximum performance increase of 13%, but the Dimensity 1200’s GPU supports Boosted overclocking.
According to MediaTek executives, the Dimensity 1200 chip was already in the planning stage as early as 2019. However, when asked why the Cortex-X1 was not utilized despite the early planning, Li Jun Nan, Director of Technical Planning for MediaTek’s Wireless Communication Division, did not provide a direct answer, only stating that the Dimensity 1200 has a 22% performance increase and a 25% energy efficiency improvement compared to its predecessor, “This is our different perspective or strategy compared to competitors.”Regarding the question of why the Dimensity 1200 uses a 6nm process instead of a 5nm process, Li Jun Nan revealed that MediaTek’s 5nm chip planning is underway, and the choice of 6nm for the Dimensity 1200 was made because MediaTek believes that TSMC’s more mature 6nm process would provide more stable performance.He also mentioned that multiple mobile devices featuring the Dimensity 1200 will be launched in the market in the first half of this year, but he did not disclose the names of the related customers.
Additionally, MediaTek announced at the launch event that they have developed PC-level game rendering technology – Ray Tracing.
In comparison, the RT ray tracing rendering provides brighter game visuals and more realistic shadow effects compared to traditional 3D rendering, significantly enhancing overall image quality.MediaTek stated that they are bringing PC-level game rendering to mobile devices, providing powerful graphics processing capabilities for game developers and terminal manufacturers, and delivering game visuals that rival reality for mobile gamers, leading the trend in mobile graphics technology.
