Towards the end of October, the premiere of the latest flagship Snapdragon 8 Gen 4 processor from the American chipmaker Qualcomm will take place, and at the same time, the announcement of the top-end Dimensity 9400 chip from Taiwanese MediaTek is expected, and now new information has appeared about the latter.
According to the well-known network informant Ice Universe on his Weibo page, the ray tracing performance in the MediaTek Dimensity 9400 chipset has improved by almost 20% compared to the previous Dimensity 9300/9300+.
The source also clarifies that this was made possible by the new ray tracing technology, which will first appear on a mobile device – it is comparable to the OMM (Opacity Micro-Maps) ray tracing technology on computers.
According to Nvidia, Opacity Micro-Maps are used to accelerate ray tracing of highly detailed geometry by “efficiently encoding the opacity states of microtragons and microgrids.”
Earlier, an insider of the Digital Chat Station said that the future Dimensity 9400 received the internal marking MT6991 (MTK6991) and will be produced using the 3nm N3E process technology from TSMC. This promises to reduce the chip’s power consumption by a decent 35%.
According to preliminary data, the MediaTek Dimensity 9400 will retain the core architecture — this is the Arm Cortex-X5 super core, which is currently being tested at 3.4 GHz, although it will be increased by the announcement, three high-performance Arm Cortex-X4 cores, as well as a quartet of Arm Cortex-A720 cores.
