喷了，被厂商忽悠买了手机被骗，反过来不喷厂商还给遮脸擦屎，这是种什么节操啊

为了彻底击溃某些三棒洗地粉， 我只好把英文原文贴给大家看看：

http://allthingsd.com/20130730/s ... laxy-s4-benchmarks/

Powered by a new Exynos 5 Octa system on a chip, the international version of Samsung’s Galaxy S4 boasts some impressive benchmarks — a graphical processing unit that runs at 532 megahertz and a central processing unit that tops out at 1.2GHz. Assuming that you’re testing the device’s performance with certain popular benchmarking software. If you’re not, those specs are liable to be a bit different.

An investigation by AnandTech reveals that Samsung has created within the Exynos 5 Octa-based Galaxy S4 a white list for certain benchmarking apps that allows them — and only them — to take advantage of the full power of the chipset. When the device detects that a white-listed benchmark app is running, it shifts into a high-performance mode not available to “real world” applications.

During normal operation, for example, the S4’s GPU operates at about 480 MHz. But if you run benchmarks on it using a benchmarking tool like GLBenchmark 2.5.1, AnTuTu or Quadrant, that frequency spikes to 532 MHz — a speed the average consumer will never experience.

The S4 exhibits similar behavior with its CPU; it typically operates at about 500 MHz with a maximum speed of about 1.2GHz. Run it through a benchmarking tool and the device automatically switches to that 1.2GHz maximum clock speed. (The same CPU behavior was observed in Qualcomm Snapdragon-powered U.S. versions of the handset.)

In other words, Samsung has optimized the Galaxy S4 to perform better in the lab than it does in the real world, enabling full-speed GPU performance only while running specific benchmarks, and maxing out CPU performance, as well. Dig around inside the device as AnandTech did, and you’ll find a code string called “BenchmarkBooster” apparently intended to produce high and repeatable performance benchmarks.

“These benchmarks appear to have been singled out for special treatment in the power/thermal management software in order to inflate scores,” Kevin Krewell, senior analyst at the Linley Group and a senior editor of Microprocessor Report, told AllThingsD after reviewing AnandTech’s findings. “It does not serve the customer in real-world situations.”

It’s hard not to view this as a sort of benchmark doping. Certainly, no real-world application running on an Exynos 5 Octa-based Galaxy S4 will ever see this kind of GPU performance — not currently, anyway. Now, to be fair, Samsung doesn’t promise a specific GPU clock speed for the S4. So this benchmark optimization that it’s engaging in isn’t quite as untoward as it seems. And one could make the argument that it’s simply intended to showcase the furthest limits of the device’s abilities — though that’s a tenuous stretch.

That said, some consumer electronics publications do use the benchmarking tools for which Samsung is optimizing in their smartphone reviews. And those that do aren’t getting the most accurate portrait of the Galaxy S4’s real-world capabilities.

Said Krewell, “Fundamentally, this shows the futility of using synthetic benchmarks without extensive screening and lab validation. When we get application benchmarks, the consumer will get a better measure of performance, but even those are not immune from being gamed.”

Samsung was not able to comment on the Exynos 5 Octa-based Galaxy S4’s benchmarking optimizations at the time of publication.


不知那些拿游戏做遮羞布的怎么看。
也就是说：
1. 三棒不仅在GPU上撒谎， 而且还在CPU上用同样的方式撒谎。
2. 这种仅在跑分时候出现的高速模式， 在平时任何应用中都不会出现， 包括游戏。

小米以跑分高为傲，你知道小米跑分为什么那么高吗？

管小米啥事…？说话讲证据，现在三星被爆跑分作假了，棒粉来救援了

就想问一句，电脑也是跑分时gpu满载，玩游戏只有部分游戏满载，大部分都跑不满，请问是不是amd、nvidia作假？

至少有游戏满载啊，但是三棒人家爆料说除了跑分超频外，其他都不能满载。况且，还是专门针对跑分软件，只要跑分软件运行，就超频，，无语

那请你把能让三棒U跑满的游戏说出来看看？那个史诗城堡的demo瞬时才30fps而且这demo又没限制到30，频率却只有480，你说做没做假

不管频率究竟是不是满载，关键是三星专门针对跑分软件写了识别程序，只要跑分软件运行就立马开高频，真是无语…如果没写识别程序，运行各种游戏跑分软件频率有高低，那可能没满载，但是针对跑分软件写了识别程序开超频，就是作弊无疑

电脑上gpu没用满但是场景帧数不足的游戏多了去了，这个跟厂商优化有很大关系。
你的意思难道是三棒玩游戏的时候故意限制gpu？故意让用户体验差点？故意让别人怀疑硬件性能？
关于这个事情，我估计你拿别的手机测试出的结果一样。

我不用手机玩游戏，这辈子三棒手机只用过一个，老古董i9000，你也不用看谁都是棒粉，只是觉得黑也别丢了最基本的逻辑。

哥，看你这么积极，请你回答我，为什么三星要针对跑分软件写了识别代码，跑分软件运行就开高频？你就回答这个问题就行了

你的意 ...

现实情况就是除了跑分别的游戏一律到不了满频，别什么故意不故意的。现在这事被挖出来瘾科技之类的媒体都报道了，要么你找个能让S4跑到满频率的游戏出来让大家闭嘴。

运行这段代码中包涵的程序，会自动提升频率。非这段代码中的程序，使用较低频率。

太神了，要不教教我们是怎么看出来的？

难道不是为了测出理论分数值？

正常的很，我跑3dmark还用afterburner固定gpu频率呢，有什么不正常的么？
再说，你说的这些算作弊么？要是这能算作弊，请问弄个650在驱动里加个识别代码跑分的时候是不是就变成titan了？
拿驱动说硬件作弊，你这是驴唇不对马嘴

现在机能过剩，谁关心跑多少分？三星的那个CPU除了现在的骁龙800，稳居第二，未必MTK方案还能比三星那个U强？
