Vivo X100 Pro suffers from severe thermal throttling with MediaTek Dimensity 9300

A recent tweet by @KaroulSahil has revealed that the Vivo X100 Pro, the first smartphone to feature the MediaTek Dimensity 9300 chipset, may have a serious issue with thermal throttling. According to the tweet, the CPU stress test on the Vivo X100 Pro showed that the Dimensity 9300 lost 46% of its performance due to overheating.

The tweet also included a screenshot of the CPU Throttling Test app, which showed that the Dimensity 9300 started with a score of 317,000 GIPS (Giga Instructions Per Second) and dropped to 171,000 GIPS after 15 minutes of testing. The app also displayed a warning message that said “Throttling detected: performance will be significantly degraded to cool down the device”.

The MediaTek Dimensity 9300 is the latest flagship chipset from the Taiwanese chipmaker, which claims to offer a 40% improvement in peak performance and a 33% reduction in power consumption compared to the previous generation Dimensity 9200. The Dimensity 9300 is also the first mobile chipset to use an all-big core CPU design, with four Cortex-X4 cores clocked at up to 3.25 GHz and four Cortex-A720 cores clocked at up to 2.0 GHz.However, the tweet by @KaroulSahil suggests that the Dimensity 9300 may not be able to sustain its high performance for long periods of time, and may suffer from thermal throttling under heavy workloads. This could affect the user experience of the Vivo X100 Pro, especially for gaming and multitasking scenarios.

The Vivo X100 Pro was launched in China on November 13 and is expected to be available in other markets soon. The X100 Pro features a 6.78-inch LTPO AMOLED display with a 120 Hz refresh rate, a 50 MP triple camera setup with a Zeiss APO 100 mm periscope lens, a 5,400 mAh battery with 100 W wired and 50 W wireless charging, and up to 16 GB of RAM and 1 TB of storage. The Vivo X100 Pro starts at CNY 4,999 ($685) for the 12/256 GB variant and goes up to CNY 5,999 ($823) for the 16/1 TB variant.
