Rumor: MediaTek is struggling with heat problem with unannounced Dimensity 9300

The upcoming MediaTek Dimensity 9300 SoC would run too hot to achieve promised performance, reports leaker Evan Blass. The release of the SoC should take place next month, because manufacturers are planning phones with the SoC in it.

The heat is because the SoC does not have economical cores, reports Blass, also known as EvLeaks, on Android Headlines. The SoC has four Arm Cortex X4 cores and four Cortex A720 cores. This means that the economical cores that are in almost every SoC are missing. When achieving the performance promised to manufacturers, this causes more heat than phones can usually dissipate.

MediaTek may now have to reduce clock speeds to keep the heat production of the SoC within limits, Blass mentions. It is also possible that manufacturers will not purchase the high-end SoC. According to rumors, the 9300 will be a SoC that TSMC makes using the N4P process. The GPU would be an Immortalis G720 from Arm, while the SoC would be the first to support LPDDR5T memory.

The Taiwanese processor designer has not announced the Dimensity 9300. Previous SoCs in the Dimensity 9000 series were always released in the autumn, after which phones with the SoC followed within a few months. Chinese manufacturers in particular use MediaTek’s more expensive socks.
