Dimensity 9300 with Four Cortex X4 Cores Throttles after Two Minute Stress Test

When unveiled the Dimensity 9300 it took the world by storm with the reveal of a performance cluster powered with four Cortex-X4 cores. So far, the high-performance Cortex-X cores were found alone in most of the recent flagship chipset arrangements. However, with its latest flagship SoC, MediaTek to raise the number from one to four.

This could mean a whole new level of performance, but at the same time, it would require more effort to keep the thermals low. With the release of the Vivo X100 Pro as the world’s first MediaTek Dimensity 9300, the first benchmarks appeared showing how this chipset performs in real life. ( ).

Vivo X100 Pro’s Dimensity 9300 Clock Speed Reaches 0. 6 GHz After Stress Test As we’ve been expecting, it won’t be an easy task to manage thermals with the MediaTek Dimensity 9300. The first Vivo X100 Pro units started to reach testers and the results are not so exciting.

In a CPU throttling test, the Octa-Core CPU throttled down to 46% of its performance in just 2 minutes time. Four of the cores lowered to 1. 2 GHz, three to 1.

5 GHz, and one to just 0. 6 GHz. For context, the MediaTek Dimensity 9300 comes with three distinct clusters.

The BIG performance core has 1 x ARM Cortex-X4 core at 3. 25 GHz, three MID performance Cortex-X4 cores at 2. 85 GHz, and four ARM Cortex-A720 cores clocked at 2 GHz.

This chipset does not bring any efficiency Cortex-A520 core. It’s a bit early to make conclusions on how the MediaTek Dimensity 9300 will perform. However, for comparison, a Qualcomm Snapdragon 8 Gen 2-equipped phone runs around 80% of its performance yield after more than 10 minutes of the CPU throttle.

Considering how quickly the 9300 throttles the performance, we are curious to see how it would perform after long times of stress. The CPU throttling test is designed to run all the CPU cores at full blast to see how the phone copes with maximum stress. The Vivo X100 Pro does come with a passive cooling solution.

The flagship packs a vapor chamber designed to move heat away from the SoC. This will bring balance to thermals and consequently to performance. The experience could be better with devices that have active cooling, like a physical fan.

Usually, gaming phones like those on the Nubia Red Magic series bring active cooling solutions. These could offer better performance with the Dimensity 9300, but there is still no word about a device with this. Gizchina News of the week These tests might suggest that the Dimensity 9300 with only performance cores will have some challenges ahead.

However, the CPU Throttling Test is meant to put one chipset’s efficiency in check. The Qualcomm Snapdragon 8 Gen 3 or A17 Pro may perform better in this test, but there are other factors that determine how hot a smartphone chipset can get. In hot and humid surroundings, the ambient temperature is higher than most regions, causing the Dimensity 9300 to thermal throttle significantly faster.

Perhaps, under normal use, the chipset won’t have major issues with performance and thermals. Of course, this is just the beginning of the road for the Dimensity 9300. So far the Vivo X100 Pro is the only device in the market with the MediaTek Dimensity 9300.

It’s just the beginning for this chipset, and also for the Vivo X100 Pro. Both MediaTek and Vivo can push future updates to improve performance and thermal management. Also, we may see further development of passive and active cooling solutions to keep this chipset’s performance under control.

The Oppo Find X7, for instance, is another device from the BBK Electronics group to embrace this chipset and it will give us another i We just hope this does not end as another Snapdragon 810 chipset. To those unaware, Qualcomm’s flagship chipset from 2015 suffered from intense throttling causing the performance to degrade considerably after a few minutes of usage. While MediaTek’s choice of bringing only performance cores to the party is a risky one, we can say that, at least, the company is trying to innovate.

There is still a full year for this chipset to prove itself. In any case, the results will determine whether or not MediaTek will repeat this core arrangement with the Dimensity 9400. .
