三星Galaxy S4跑分被曝作假 专为跑分程序优化

棒子干出这种事情一点都不出意外,棒子向来就不要脸。

这个本来就是533的mhz的GPU  怎么叫超频

其它软件用480不是为了省电吗  而这几个分数软件不是要GPU全力啊  上533不对吗
你这洗地的水平不行啊
"不过在运行GLBenchmark 2.5.1、安兔兔和Quadrant时,设备会自动将主频提升至532MHz。"
换句话说, 这个CPU在任何时候都是480MHZ, 除了在跑分的时候。 那你说这跑的分有意义吗?
你听说过CPU跑分是测超频后的结果吗?

用额定频率跑benchmark叫作假,狗粉这脸皮比棒子不遑多让啊
棒子粉又来自欺欺人人了, 好一个平时都不使用, 只在跑分时使用的“额定频率”。

而且棒子还在系统上做手脚, 只要跑跑分程序, 就提升CPU频率, 这不要脸的手法还有石油大婶这样的棒粉来洗地捧臭脚, 实在是不能理解棒粉是怎么样的一群人。

文中明明说的是“但在某些游戏中主频却没有这么高”,你这里就变成了“平时都不使用”
这些跑分程序是游戏吗?

哦哦,也许你看不懂文章,这也难怪,我就说怎么可能有用户自费给厂商擦屎。

那我解释一下:



运行这段代码中包涵的程序,会自 ...
你有见过某操作系统在发现某 Process 名称是已知跑分程序时,自动超频的吗?

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。

难道不是为了测出理论分数值?
测出理论分数值难道不是应该用液态氮冷却,再超频到极限吗?

s4我不了解,如果三星标的gpu就是532的频率,请问哪个地方作弊了?
请问显卡那么多的boost版本,是不是更应该算作弊,而且做的不是一星半点的弊了?
你是不懂英文,还是睁眼瞎,还是选择性失明啊?
你没看我贴的英文吗? 532Mhz是仅用于实验室测试,任何软件都不会开启这个频率, 除非那几个跑分程序。

这就相当于MS在操作系统里做手脚, 一旦发现用户在跑分, 就软超频CPU, 你懂这个意思吗? 还在这里唧唧歪歪。

f大神,你是屎吃多了见谁都喷粪么?
你那文章哪里有证据确认了这532是超频后的频率还是默认频率?

尼玛一个仅在实验室里才出现,产品里不会出现的设置还叫默认设置?默认你个JJ

而且我们说的超频用户可控,软超硬超都可以,超好了以后对所有应用有效。棒子的只能通过系统后门,跑分程序一完立马打回原形。连这样的臭脚你还洗得欢,香吗?

虚拟大神,跑分只能在实验室跑么?
跑分软件是实验室专用么?
就你这破壁逻辑,真是不改你多年来脑袋进水的风格。
你是装蠢还是真蠢啊,人家在开后门你懂不?为了棒子连下限都不要了?
