联发科处理器被抓跑分“作弊”：P95性能比天玑1000L还高

对于智能手机在跑分当中作弊这样的事情，相信大家都已经见怪不怪了。在早两年的时间里，这个事情被讨论得十分激烈，当时有手机厂商在系统里插入了相关代码，在运行跑分测试软件的时候开启“高性能”模式，来获取比较高的测试成绩。而被抓现行的手机厂商对于“跑分”作弊的解释是G n t g ; l，这是H / j a ~为了充分显示手机产品的计算能力t F { t q 2 _ * ; h个就是手机厂商的问题了。可是现在，SoC供应商直接把当年x t h W _ %手机厂商的“作弊”思路直接做到了自己的产品中。没错，现在被抓现行的这个SoC厂商就是联发科。AnandTech在进行Reno3 Pro海外版（搭载联发科Helio P95）的基准测试的时候，联发科P95处理器的PCMa1 0 Z U = yrk成绩大大超出了这颗处理器a = H 4 Q q h , q本身“该有的! 6 t m {性能表现”。然后外媒对比了搭C z } ) Y 6载天玑1000L的版本$ 7 : S * v { t，发现P95的性能q a u ) R , 0 {比天玑1000L的还要高。

在联发科r E Q S u M p =的产品线中，P95的定位是要比天玑2 O . M 6 Y #1000L要低的，基准测试成绩不如天玑1000L才是一个合理的现象。基^ h b D r ; Y于上述不合理的情况，外媒就挖出了联发科处理器跑分作弊的事情。联发科在SoC的BSP固件中直接内置了一个power_whitelist_cfg.xml 文件，这个就是一个白名单文件，把目前市面上的基g l W 3 f & 1准测试App列了个遍，然后运行测试的时候火力T B y Y P a d H全开甚至“超频”，无视温控，来获得更高的测试成绩。联发科在固件中内置白名单的行为，并非只出现在OPPO的手机当中，外媒还发现在其他使用联发科处理器的产品当中发现了同样的白名单文件。

对于跑分“作弊”的情况，联发科方面的回应如下：

MediaTek follows accepted industry standards anI t ) X )d{ 6 ) D J b 2 Z is confident that benchm5 n O b m 1 r J Sarking tests accurately represent the capabilities of our chipsets. We work closely with global device makers when it comes to tesA I }ting and benchmarking devices powered by our chiC % # ?psets, but ultimately brands have the flexibility to configure their own devices aT h $ ws they see fit. Many companies dp O %esign devices to run on the highest possible performanR j 6 n s z g _ce levels when benchmarking tests are running in order to show the full capabilities of the chipset. This reveals what the upper end of performance capabilitiesq R l z ^ are on any given chipset.

Of course, in real world scenarios there are a multitude of fag O ! @ctors that will determine how chipsets perform. MediaTek’s chipsets are designed to optimize power and performance to prom q i u 0 v f Rvide the best user experience possible while maximizing battery lifC L h %e. If someo( a G Gne is running a compute-intensive program like a demanding game, the chipset will intelligently adapt to computio @ e J 7 s L l 4ng patterns to deliver su 6 y astained performance.

大概的意思就是基准测试的成绩充分说明了它们产品的性能特性，是处T V ; * z e Q h R理器本身拥有的能力的表现，所以也并不算“作弊”，他们的做法其实和其他公司的做法是一致的。然后，联发科N X L : M和各家手机厂商之间进行合作，来优化功耗和性能之间的平衡，最终手机厂商可以灵活地配置自己认为合适的X , C N设备。

但是，在进行PCMark等基准测试的时候F 8 @ +，实际考验的是设备整体的响应能力，而非芯片组本身。这样其实就不符合联发科所指的在实际应用当中提供性能和功耗之间的平衡; V I t N动态1 J 7 )调整的理念。
