MediaTek Dimensity 9400e launched with AI-Powered APU 790, Debuts in OnePlus Ace5 Racing Edition
MediaTek has launched its latest processor in the 9400 series, the Dimensity 9400e SoC, an upgraded version of last year’s Dimensity 9300+, at the OnePlus Game Strategic Communication Conference in China.
Built on TSMC’s 4nm process, the Dimensity 9400e maintains the series’ high-performance CPU architecture, featuring a 3.4GHz Cortex-X4 prime core, three 2.85GHz Cortex-X4 performance cores, and four 2.0GHz Cortex-A720 efficiency cores.
It integrates a 12-core Immortalis-G720 GPU, which supports advanced graphics features like hardware-based ray tracing, along with technologies such as Star Speed Engine Adaptive Control 2.0 and Dimensity Frame Double Technology 2.0+.
The chipset also supports the Dimensity AI development kit and enhanced inference decoding capabilities, enabling efficient end-to-end operation of leading large language models like DeepSeek-R1-Distill and LLaVA-1.5 7B.

Availability -
The first smartphones powered by the Dimensity 9400e chipset will hit the market later this month. OnePlus will be the first to adopt the new chip, followed by realme, which is expected to feature it in the upcoming realme Neo7 Turbo, also launching this month.
OnePlus Ace5 Series to Debut Dimensity 9400e -
OnePlus has officially announced that its OnePlus Ace5 Racing Edition, launching in China next week, will be the first device equipped with the Dimensity 9400e. The phone will come preloaded with the proprietary Fengchi Gaming Kernel, designed to push gaming performance to new heights.
According to OnePlus, the Ace5 Racing Edition sets a new industry benchmark by achieving both the highest average frame rate and the strongest 1% low frame performance—a feat made possible by the Fengchi Gaming Kernel.
Louis Jie, Head of OnePlus China, said:
The gamers demand smoother experiences, and average frame rate alone is no longer a sufficient metric. He highlighted the importance of the 1% low frame rate, which represents the lowest frame rates seen during the most crucial gameplay moments—such as combat, high-speed driving, or critical action scenes. A higher 1% low frame rate ensures smoother performance exactly when it matters most.
Jie called on the industry to adopt the 1% low frame metric as a key standard alongside average frame rate to better reflect real-world gaming smoothness.
OnePlus Ace5 Racing Edition -
OnePlus claims the Ace5 Racing Edition will deliver unmatched gaming performance in its price segment, outperforming all competitors under 2,500 yuan (approximately USD 346 / Rs. 29,610).
