As the new vivo X100 Pro ends up in the hands of enthusiastic testers, we can finally get an idea of the thermal performance of the MediaTek Dimensity 9300 chipset with its four Cortex
As expected, cooling a chipset with four high-performance cores is a tall order. In a popular CPU throttling test, the eight-core processor dropped to 46% of its performance in just 2 minutes. Four cores were downgraded to 1.2GHz, three to 1.5GHz, and one to just 0.6GHz, compared to a potential 3.25GHz Cortex-X4 core, three 2.85GHz Cortex-X4 cores and four 2GHz Cortex-A720 cores.
The Dimensity 9300 reached 46% of its performance in just 2 minutes
Just as a point of reference, a phone equipped with the Snapdragon 8 Gen 2 usually reaches around 80% of its performance after more than 10 minutes of CPU throttle testing in our tests.
The CPU throttling test is designed to run all CPU cores at full capacity to see how the phone handles maximum stress. The vivo X100 Pro, like most other flagship phones, has a passive cooling solution, in this case a vapor chamber designed to move heat away from the SoC. You might expect better performance from a device with active cooling, such as a fan, but we have yet to see such a phone with the Dimensity 9300.
