Being accused of cheating on performance scores, MediaTek responded that this was ‘normal as usual’.

Over the past few years, we’ve seen a lot of “missions” related to cheating performance scores on Android devices to “color” as well as attract the attention of users, mainly. from individual smartphone manufacturers. However, recently new reports from Anandtech have shown that MediaTek itself, the major mobile chipset manufacturer, is also showing signs of performance fraud on some chips.

Specifically, Anandtech has discovered evidence that MediaTek has been cheating the performance score when comparing between Helio P95 chip on OPPO Reno3 Pro (European version) and Dimensity 1000L chip on OPPO Reno3 (Chinese version). ).

OPPO Reno3 Pro European version runs Helio P95

Performance test results by the dedicated PCMark application showed that the Reno3 Pro running Helio P95 beat Reno3 running Dimension 1000L. Anandtech said this is actually quite strange and there is something wrong, because the Cortex-A75 core in the Helio P95 chip is 2 years older than the Cortex-A77 core in the 1000L Dimensity chip, besides Helio P95 only there are two A75 cores, while the 1000L Dimensity has four newer A77 cores. So there is no way the performance of the Helio P95 chip can outperform the 1000L Dimensity chip.

Anandtech then tested the performance of the Reno3 Pro by installing an anti-fraud version of PCMark, which will have the application package name changed so that smartphone manufacturers cannot determine if it has Must have performance scoring app or not. The result was a surprise when the performance of OPPO Reno3 Pro dropped by 30% compared to the original, even in some tests, the performance score also dropped to 75%.

Anandtech also tried running PCMark anti-fraud application on Chinese Reno3 Pro 5G version running Snapdragon 765G chip and found no fraud.

Detecting hidden performance mode on smartphones running MediaTek chips?

After digging into the system of the Reno3 Pro running the Helio P95 chip, Anandtech found an implicit performance application called “Sport mode”. This application is supposed to control the system to increase the performance level whenever a benchmark application is detected.

Proof of Sport mode is found

Anandtech also said that not only OPPO smartphones have this Sport mode implicitly installed, but other smartphones such as Realme C3, Xiaomi Redmi Note 8 Pro or Sony Xperia XA1 have found similar applications. The Xperia XA1 was launched in early 2017 and so it seems that MediaTek has been performing performance fraud for a very long time without being detected.

The implicit performance application was extracted from Anandtech’s firmware version from OPPO Reno3 Pro, but in subsequent updates, MediaTek tried to hide this hidden performance application, but it seems that the performance score cheating continue to this day.

MediaTek feedback

Immediately after Anandtech posted a MediaTek “cheat” fraud on the performance of its chips, MediaTek also posted an explanation on this issue.

“MediaTek adheres to accepted industry-leading standards and we are confident that performance tests accurately reflect the actual performance on our chipsets. We work closely with smartphone manufacturers. globally when it comes to testing the performance of MediaTek chips, manufacturers can flexibly tweak the device to suit their needs. Their smartphone can run at the highest performance level when running performance tests, this is to show the power of the chip on the device tested, and shows that any chip has can achieve the highest level of performance.

Of course, in real-world use, there are many factors that will determine how well a chip will perform. MediaTek’s chips are designed to optimize performance as well as power consumption, to provide the best possible user experience while maximizing battery life. If users run computing tasks such as heavy gaming, the chip intelligently adapts to the running task to provide a stable performance. This means users will notice different levels of performance when running different applications because the chip automatically manages CPU, GPU and memory resources depending on the battery capacity and performance needed. to be able to provide the best user experience. In addition, some other manufacturers have different modes enabled in different markets, so the performance of the device may vary based on regional standards.

We believe that maximizing the performance of the chips in performance tests is in accordance with the practices of other companies, and gives users the most accurate view of the performance of the chip. device.”

So we can see, the performance cheating is explained by MediaTek that this is a reasonable job and it shows users the maximum performance level that the device can achieve, not for the purpose of ostentation. The performance or cheating of any parameters is beyond the capabilities of the chip.

MediaTek even criticized Anandtech when it was suspicious of “performance optimization”, claiming that this is a common practice at the present time, even other smartphones running chipsets other than MediaTek do the same thing. similar (refers to Qualcomm’s Snapdragon chip).
