MediaTek’s Dimensity 9300 Loses 46 Percent Of Its Performance Due To Throttling In New Stress Test As Vivo X100 Pro’s Vapor Chamber Submits

wccftech.com:

The Dimensity 9300 did not stick with a traditional CPU cluster like the Snapdragon 8 Gen 3 this year, with the biggest difference between the two chipsets being the lack of efficiency cores on MediaTek’s current flagship SoC. While the advantage here is that the Dimensity 9300 can deliver incredible overall performance by surpassing Apple’s A17 Pro GPU, it is at the expense of increased power consumption. In a new CPU stress test, the crack in the silicon’s armor has been displayed, all the while running in an Android flagship that has a capable cooling solution.

Most Android flagships, like the X100 Pro, sport a vapor chamber designed to keep the temperatures of the Dimensity 9300 in check. Unfortunately, despite being mass produced on TSMC’s power-efficient N4P process, the lack of low-power cores on the latest SoC means that it will have a higher power draw than the Snapdragon 8 Gen 3 and A17 Pro. Due to this change, Sahil Karoul demonstrated on X that running the CPU Throttling Test results in the thermal throttling of the silicon in just two minutes.

For those that do not know, the CPU Throttling Test loads the Dimensity 9300’s 8-core CPU with up to 100 threads and measures performance. Looking at the graph, one of the core’s clock speeds drops to 0.60GHz, with the remaining cores reduced to a frequency of 1.20GHz and 1.50GHz. By default, the chip’s maximum clock speed is 3.25GHz, which is for the Cortex-X4. According to the results, the Dimensity 9300 performance dropped by 46 percent due to running the stress test.

Even though these tests suggest that MediaTek should not have switched to a CPU cluster with
