Oddly configured Dimensity 9300 SoC throttles throughout stress take a look at dropping 46% of its efficiency

Earlier this 12 months we advised you concerning the uncommon configuration of MediaTek’s new flagship Dimensity 9300 chipset. The octa-core processor consists of 4 Cortex-X4 Prime CPU cores and 4 Cortex-A720 Efficiency CPU cores. There aren’t any low-power Effectivity CPU cores that different software processors have. Whereas which means that the Dimensity 9300 SoC is highly effective, it additionally signifies that the chipset is susceptible to overheating.

The Dimensity 9300 throttled its efficiency by 46% in the course of the CPU Throttling Take a look at

Making this example worse is that the chip was examined on the Vivo X100 Professional which encompasses a vapor chamber which is a warmth pipe used to dissipate warmth to the good space of the chamber and away from the chipset. Though the Dimensity 9300 is produced utilizing TSMC’s energy-efficient N4P 4nm course of node, the throttling of the chip began in simply two minutes.
