MediaTek Dimensity 9300+

The MediaTek Dimensity 9300+ (9300 Plus) is a high-end SoC for smartphones and tablets based on Android. For the first time, the CPU no longer uses classic energy-saving cores, but only so-called big cores. The CPU part integrates a fast ARM Cortex-X4 core with up to 3.4 GHz, three lower clocked X4 cores with up to 2.9 GHz and four smaller Cortex-A520 cores with up to 2 GHz. The fast prime core is also the difference to the identical Dimensity 9300. As with the latter, the SoC offers a large 18 MB level 3 cache.

As expected, the performance in initial benchmarks with a Xiaomi 14T Pro is slightly faster than the Dimensity 9300 and comparable to a Snapdragon 8 Gen 3 (in Geekbench 6). In PCMark and Crossmark, the performance is slightly worse and more at the level of a Qualcomm Snapdragon 8 Gen 2.

The integrated MediaTek APU 790 fully relies on Generative AI and aims to accelerate adapted algorithms by a factor of eight. Energy efficiency is said to have been improved by 45 percent. With the MiraVision 990, displays can be operated in Ultra HD at up to 120 Hz and Google Ultra HDR image display (from Android 14) is also supported.

The graphics unit is an ARM Immortalis-G720 MP12 is used.

The SoC is manufactured using the 3rd generation 4-nanometer process at TSMC (N4X).
