Vivo is gearing up to unveil its X200 series smartphones, anticipated to include the MediaTek Dimensity 9400 chip, on October 14. Yet, the official release date for the chip itself remains under wraps.
A recent leak from tipster Digital Chat Station on Weibo, China's social media site, has shed some light on this. According to the leak, the Dimensity 9400 is set to be announced on October 9. If this proves true, MediaTek might soon begin teasing the launch.
Rumored Specifications of MediaTek Dimensity 9400
The Dimensity 9400 is expected to utilize TSMC's 3nm N3E node technology for the first time, potentially offering up to a 30% increase in energy efficiency compared to its predecessor. This improvement could translate into better battery life for devices powered by this chip.
Performance-wise, the Dimensity 9400 will sport an octa-core CPU configuration, as indicated by a recent Geekbench AI benchmark listing. It will feature one high-performance Cortex-X5 core at 3.63 GHz, three Cortex-X4 cores at 2.80 GHz for additional power, and four Cortex-A725 cores operating at 2.10 GHz for routine tasks.
This represents a noticeable enhancement in clock speed over the Dimensity 9300, particularly with the prime core, which has jumped from 3.25 GHz to 3.63 GHz.
Competitive Landscape
Despite these improvements, MediaTek faces stiff competition. Qualcomm's Snapdragon 8 Gen 4 is rumored to achieve a peak clock speed of 4.32 GHz, while Apple's A18 series is expected to reach 4.04 GHz.
Regarding the GPU, it is believed to be part of the Immortalis G9xx series. It is projected to deliver 110fps in the GFXBench Aztec Ruins test at 1440p resolution—an 11.1% improvement over the previous generation's 99fps.
