CPU Enhancements
Like the Dimensity 9300, the 9400 features powerful CPU cores, but it utilizes TSMC’s 3nm process, boosting both performance and energy efficiency. The new chip includes a Cortex-X928 running at up to 3.63GHz, three Cortex-X4 cores at 3.3GHz, and four Cortex-A720 cores at 2.4GHz. The Dimensity 9300, on the other hand, maxes out at a Cortex-X4 core with 3.25GHz, three Cortex-X4 cores at 2.85GHz, and four Cortex-A720 cores running at 2GHz.
The addition of a high-performance Cortex-X925 CPU core in the Dimensity 9400 allows for improved single-core performance by 35% and multi-core performance by 28%. With TSMC’s advanced 3nm technology, this chip offers greater performance per milliwatt, boasting a 40% increase in power efficiency compared to its predecessor. Additionally, it features double the L2 cache and 50% more cache than the Dimensity 9300, contributing to this performance leap.
GPU Improvements
Equipped with a new 12-core Immortalis G925 GPU leveraging Arm’s fifth-generation architecture, the Dimensity 9400 delivers a 41% increase in peak performance while also being 44% more power efficient than the previous model. The enhancement in ray tracing performance is notable, with a 40% uplift. Gaming experiences are smoother as well, thanks to upgraded MediaTek HyperEngine gaming technologies like MediaTek Adaptive Gaming Technology 3.0 and MediaTek Frame Rate Converter.
Camera Upgrades
The camera features are significantly enhanced too. The new Imagiq 1090 ISP in the Dimensity 9400 allows for HDR video capture across the zoom range, a first among flagship chips. It also introduces Gen-AI Super Resolution and Gen-AI Super Zoom, which refine blocky images into sharp ones and achieve up to 100X magnification with clarity, respectively. Both chips can support 320MP resolutions, but the Dimensity 9400 can record at 8K/60fps, while the Dimensity 9300 tops out at 8K/30fps.
AI and Connectivity Advancements
AI improvements are a highlight of the Dimensity 9400. It incorporates an 8th-generation NPU that enhances on-device AI functions. This chip enables high-quality on-device video generation and LoRA training, claiming to deliver 100% faster diffusion generation and 80% quicker LLM prompt performance, with 35% better power efficiency compared to the Dimensity 9300.
Connectivity also sees upgrades, with a 50% increase in power efficiency for Wi-Fi and Bluetooth. The new 5G modem allows direct Bluetooth connections between smartphones up to 1.5km apart, and with MediaTek Xtra Range 3.0, the chip can extend Wi-Fi coverage by 30 meters. Additionally, it can cut Wi-Fi hotspot power usage by half, and memory speeds have risen to 10667Mbps from 9600Mbps.
Final Thoughts
The MediaTek Dimensity 9400 is a significant leap in CPU and GPU capabilities, making it one of the top flagship smartphone chips available. It not only competes with Apple and Qualcomm but also enhances nearly every aspect, including AI, camera capabilities, and connectivity. This chip is already featured in devices like the Vivo X200 and Find X8 series, with more flagship models expected to follow suit.
