聯發科處理器被抓跑分“作弊”:P95性能比天璣1000L還高

對於智能手機在跑分當中作弊這樣的事情,相信大家都已經見怪不怪了。在早兩年的時間裡,這個事情被討論得十分激烈,當時有手機廠商在系統裡插入了相關代碼,在運行跑分測試軟件的時候開啟“高性能”模式,來獲取比較高的測試成績。而被抓現行的手機廠商對於“跑分”作弊的解釋是,這是為了充分顯示手機產品的計算能力,不考慮其他因素完全釋放CPU的性能,而在現實當中需要考慮續航、發熱等各方面的因素。

如果當時的“高性能”模式是手機廠商搞出來的么蛾子的話,那麼這個就是手機廠商的問題了。可是現在,SoC供應商直接把當年手機廠商的“作弊”思路直接做到了自己的產品中。沒錯,現在被抓現行的這個SoC廠商就是聯發科。AnandTech在進行Reno3 Pro海外版(搭載聯發科Helio P95)的基準測試的時候,聯發科P95處理器的PCMark成績大大超出了這顆處理器本身“該有的性能表現”。然後外媒對比了搭載天璣1000L的版本,發現P95的性能比天璣1000L的還要高。

在聯發科的產品線中,P95的定位是要比天璣1000L要低的,基準測試成績不如天璣1000L才是一個合理的現象。基於上述不合理的情況,外媒就挖出了聯發科處理器跑分作弊的事情。聯發科在SoC的BSP固件中直接內置了一個power_whitelist_cfg.xml 文件,這個就是一個白名單文件,把目前市面上的基準測試App列了個遍,然後運行測試的時候火力全開甚至“超頻”,無視溫控,來獲得更高的測試成績。聯發科在固件中內置白名單的行為,並非只出現在OPPO的手機當中,外媒還發現在其他使用聯發科處理器的產品當中發現了同樣的白名單文件。

對於跑分“作弊”的情況,聯發科方面的回應如下:

MediaTek follows accepted industry standards and is confident that benchmarking tests accurately represent the capabilities of our chipsets. We work closely with global device makers when it comes to testing and benchmarking devices powered by our chipsets, but ultimately brands have the flexibility to configure their own devices as they see fit. Many companies design devices to run on the highest possible performance levels when benchmarking tests are running in order to show the full capabilities of the chipset. This reveals what the upper end of performance capabilities are on any given chipset.

Of course, in real world scenarios there are a multitude of factors that will determine how chipsets perform. MediaTek’s chipsets are designed to optimize power and performance to provide the best user experience possible while maximizing battery life. If someone is running a compute-intensive program like a demanding game, the chipset will intelligently adapt to computing patterns to deliver sustained performance. This means that a user will see different levels of performance from different apps as the chipset dynamically manages the CPU, GPU and memory resources according to the power and performance that is required for a great user experience. Additionally, some brands have different types of modes turned on in different regions so device performance can vary based on regional market requirements.

We believe that showcasing the full capabilities of a chipset in benchmarking tests is in line with the practices of other companies and gives consumers an accurate picture of device performance.

大概的意思就是基準測試的成績充分說明了它們產品的性能特性,是處理器本身擁有的能力的表現,所以也並不算“作弊”,他們的做法其實和其他公司的做法是一致的。然後,聯發科和各家手機廠商之間進行合作,來優化功耗和性能之間的平衡,最終手機廠商可以靈活地配置自己認為合適的設備。

但是,在進行PCMark等基準測試的時候,實際考驗的是設備整體的響應能力,而非芯片組本身。這樣其實就不符合聯發科所指的在實際應用當中提供性能和功耗之間的平衡動態調整的理念。
