Ryzen 7 3700X(Ryzen 7)是AMD在 2019 年发布的最好的处理器之一。Ryzen 7 3700X 拥有 8 个内核和 16 个线程，以3.6 GHz的(GHz)基本时钟(base clock)运行，并且能够提升到最高 4.4 GHz，提供在价格和性能(price and performance)之间取得了很大的平衡。它是一款高性能处理器(performance processor)，无论是在游戏机中，还是在视频编辑(video editing)等多线程情况下。但是，我们不禁问自己：如果我们要超频AMD Ryzen 3700X，它会变得更强大吗？在本文中查看超频此处理器时的收获和损失：
超频AMD Ryzen 7 3700X：我们是如何做到的？
Ryzen 7 3700X拥有 8 个物理核心、16 个线程，运行频率为 3600 MHz，最高可达 4.4 GHz，4 MB二级(Level 2)缓存和 32 MB三级(Level 3)缓存。这款CPU采用仅 7 纳米的制造工艺(manufacturing process)，不仅速度快，而且节能，TDP 低至仅 65瓦(Watts)。
对处理器进行超频是一项相当复杂的任务。您所体验的结果取决于您拥有的计算机。然而，超频最重要的元素是良好的主板和出色的散热。这就是为什么在我们向您展示我们的AMD Ryzen 7(AMD Ryzen 7) 3700X 处理器保持稳定的最大频率之前，我们想分享一下我们为此目的使用的硬件配置：(hardware configuration)

华硕 ROG Crosshair VIII Hero(ASUS ROG Crosshair VIII Hero) ( Wi-Fi ) 主板拥有出色的UEFI BIOS(UEFI BIOS)，其中包含丰富的功能和选项，您可以随意调整。这就是为什么我们选择从UEFI BIOS中对处理器进行超频，而不是使用AMD的Ryzen Master 软件(Ryzen Master software)。
经过数小时的测试和尝试但失败后，我们设法将AMD Ryzen 7 3700X 超频至 4.25 GHz的速度，电压为 1.40。不仅如此，系统就会崩溃并变得无法使用。
我们在超频的AMD Ryzen 7(AMD Ryzen 7) 3700X (4.25 GHz )上设法达到的最大速度比其 3.6 GHz 基本(GHz base) 时钟速度(clock speed)高 18% 。您还应该注意到我们进行了全核超频(all-core overclock)这一事实，这意味着AMD Ryzen 7 3700X 上的所有内核都以 4.25 GHz运行。为了查看处理器性能(processor performance)是更好还是更差，我们运行了两次相同的基准测试，一次是在以股票速度(stock speed)运行时，一次是在CPU超频时。所有基准测试均在Windows 10 Pro版本 1903(version 1903)上运行，构建 18362.388，以及可用的最新驱动程序。
现在让我们看看我们在游戏和基准测试中的结果：
超频AMD Ryzen 7 3700X是否会提升性能？(performance boost)
我们从CPU-Z 单线程基准测试(CPU-Z Single Thread benchmark)开始，它测试处理器的单核性能。AMD Ryzen 7 3700X超频至 4.25 GHz时，我们得到了 513 分，这比我们在标准时钟速度下运行时得到的 520 分略低（速度下降(speed decrease)了 1.35%）。这是因为超频处理器的 4.25 GHz 频率(GHz frequency)低于Ryzen 7 3700X 通过其Precision Boost 功能自动达到的(Precision Boost feature)默认 4.4 (default 4.4) GHz 升压(GHz boost)时钟。
在CPU-Z 多线程测试(CPU-Z Multi Thread test)中，超频的AMD Ryzen 7 3700X 获得了 5720 分的成绩。与处理器的库存速度相比，增加了 3.91 % increase
在Cinebench R20中，超频至 4.25 GHz的(GHz)Ryzen 7 3700X比其默认出厂版本(default factory version)快 5.19% 。
在Blender中，超频的Ryzen 7 3700X 也更快，大约一分钟。与在工厂时钟运行时相比，在Blender中完成两个场景的渲染所花费的时间提高了 6.63% 。
PCMark 10告诉我们处理器在日常计算任务中的能力，例如网页浏览(web browsing)、视频会议(video conferencing)、应用程序启动时间、生产力和数字内容创建(content creation)。在这个基准测试中，超频的AMD Ryzen 7 3700X 比普通版(stock version)慢了 2.57% 。
在7-Zip的基准测试中，超频的锐龙7 3700X 在测试(Ryzen 7)文件压缩速度(file compression speed)时与非超频版本一样快。
我们在7-Zip(7-Zip)的解压测试(decompression test)中也看到了相同的性能：超频和库存 Ryzen 7(stock Ryzen 7) 3700X 的结果相同。
我们还在 Google Chrome 中运行JetStream 2(Google Chrome)来(JetStream 2)检查处理器在浏览网页时的速度。再一次(Again)，我们得到了相同的分数，无论我们是使用普通时钟(stock clock)速度还是超频AMD Ryzen 7 3700X 。
如果您想对处理器进行超频，那么您很有可能是一名希望在玩游戏时尽可能发挥最大性能的游戏玩家。这就是为什么我们也跑了几场比赛。我们使用了 1080p 分辨率和每个可用的最低图形细节，因此视频卡(video card)不会减慢处理器的速度。
在《古墓丽影(Tomb Raider)之影(Shadow)》中，CPU Render 测量(CPU Render measurement)显示，超频后的锐龙7(Ryzen 7) 3700X 生成的帧数比出厂版本少 8 帧。
在Metro Exodus中，我们发现(Metro Exodus)AMD Ryzen 7 3700X 的普通(AMD Ryzen 7)版(stock version)和超频版没有区别，两者都达到了每秒 91 帧。
在World War Z中，在(World War Z)Vulkan上运行，超频的Ryzen 7 3700X 渲染的帧数比其出厂版本少两帧。
我们本来希望展示运行Prime95的超频处理器的温度和功耗(power consumption)。但是，在这个应用程序中，我们超频的AMD Ryzen 7 3700X 拒绝通过。每次我们尝试运行Prime95时，计算机都会由于超频处理器达到的临界温度而关闭。
但是，我们能够在运行Blender时监控温度和(Blender)功耗(power consumption)——这是一个最大限度地使用处理器的渲染基准(rendering benchmark)。为了检查处理器的温度和功率，我们使用了 HWiNFO64(HWiNFO64)。Ryzen 7 3700X 在使用工厂时钟时达到的最高温度为 85摄氏度(Celsius)（185华氏度(Fahrenheit)），低于其官方最高温度 95 度。但是，当我们对其进行超频时，它超过了官方的最大值，达到了 98摄氏度(Celsius)（208华氏度(Fahrenheit)）。这样的温度会影响处理器的寿命。
至于功耗(power consumption)，Ryzen 7 3700X在运行Blender时最大消耗 90(Blender)瓦(Watts)。超频时，它的瓦数上升到明显更高的 121瓦(Watts)。
结论：不要费心超频AMD Ryzen 7 3700X
我们对基准测试(benchmarking experiment)的结果不满意，原因如下：
- 在某些基准测试中，我们注意到超频导致性能损失(performance loss)
- 我们确实看到了渲染基准(rendering benchmarks)的改进，其中多线程性能至关重要。但是，对于大多数用户来说，它们可以忽略不计
- 工作温度升高很多，对处理器的寿命产生负面影响
- 耗电量上升很多
我们建议您使用默认设置的AMD Ryzen 7 3700X 处理器。只要AMD的算法认为有必要，就让Precision Boost 功能有效地动态提升工作频率。(Precision Boost feature)我们对Precision Boost及其性能影响(performance impact)进行了分析，结果令我们惊喜。有关更多详细信息，请阅读：Precision Boost对AMD Ryzen处理器的性能影响。(performance impact)
我们的结论是，您从现有的 AMD Ryzen 7 3700X 获得的整体体验比将其超频至 4.25 GHz 时要好得多。(Our conclusion is that the overall experience you get from the stock AMD Ryzen 7 3700X is a lot better than when overclocking it to 4.25 GHz.)

Overclocking the AMD Ryzen 7 3700X: What you get and what you lose? -
Ryzen 7 3700X is one of the best processors released by AMD in 2019. With its eight cоres and sixteen threads, running at a base clock of 3.6 GHz, and having the ability to boost tо a maxіmum of 4.4 GHz, the Ryzen 7 3700X offers a great balance between price and perfоrmance. It is a hіgh performance processor, both in gaming machines, as well as in multi-threaded situations, like video editing. However, we could not refrain from asking ourselνes: if wе were to overclock thе ΑMD Ryzen 3700X, would it become even more pоwerful? Ѕee what you gain and what you lose, when overclocking thіѕ рrocessor, in this article:
Overclocking the AMD Ryzen 7 3700X: How did we do it?
The Ryzen 7 3700X has eight physical cores, 16 threads, running at 3600 MHz, and going up to 4.4 GHz, 4 MB of Level 2 cache, and 32 MB of Level 3 cache. This CPU is built on a manufacturing process of just 7 nanometers, and it is not just fast, but also energy-efficient, coming with a low TDP of only 65 Watts.
Overclocking a processor is a rather complex task. The results you experience depend on the computer that you have. However, the most important elements for overclocking are a good motherboard and excellent cooling. That's why, before we show you the maximum frequency at which our AMD Ryzen 7 3700X processor remained stable, we would like to share the hardware configuration that we used for this purpose:
The ASUS ROG Crosshair VIII Hero (Wi-Fi) motherboard has an excellent UEFI BIOS, which is rich in features and options that you can tweak as you like. That's why we chose to do the overclocking of the processor from the UEFI BIOS instead of using AMD's Ryzen Master software.
After hours of testing and trying but failing, we managed to overclock the AMD Ryzen 7 3700X to a speed of 4.25 GHz, on a voltage of 1.40. Any more than that, and the system would crash and become unusable.
The maximum speed that we managed to reach on our overclocked AMD Ryzen 7 3700X (4.25 GHz) is 18% higher than its 3.6 GHz base clock speed. You should also take note of the fact that we did an all-core overclock, which means that all the cores on the AMD Ryzen 7 3700X were running at 4.25 GHz. To see whether the processor performance is better or worse, we ran the same benchmarks twice, once when running at stock speed and once when the CPU was overclocked. All the benchmarks were run on Windows 10 Pro, version 1903, build 18362.388, and the latest drivers available.
Now let's see what results we have had in games and benchmarks:
Do you get a performance boost from overclocking the AMD Ryzen 7 3700X?
We started with the CPU-Z Single Thread benchmark, which tests the single-core performance of the processor. With the AMD Ryzen 7 3700X overclocked at 4.25 GHz, we got a score of 513 points, which is a bit lower than the 520 points that we got when running at the standard clock speeds (a speed decrease of 1.35%). That's because the 4.25 GHz frequency of the overclocked processor is lower than the default 4.4 GHz boost clock, reached by the Ryzen 7 3700X automatically, through its Precision Boost feature.
In the CPU-Z Multi Thread test, the overclocked AMD Ryzen 7 3700X got a score of 5720 points. It is a 3.91% increase compared to the stock speeds of the processor.
In Cinebench R20, the Ryzen 7 3700X overclocked at 4.25 GHz was 5.19% faster than its default factory version.
In Blender, the overclocked Ryzen 7 3700X was also faster, by approximately one minute. Compared to when running at factory clocks, this is an improvement of 6.63% for the time spent to finish the rendering of the two scenes in Blender.
PCMark 10 tells us how capable a processor is in daily computing tasks such as web browsing, video conferencing, apps start-up times, productivity, and digital content creation. In this benchmark, the overclocked AMD Ryzen 7 3700X was slower by 2.57% compared to the stock version.
In 7-Zip's benchmark, the overclocked Ryzen 7 3700X was as fast the non-overclocked version while testing the file compression speed.
We also saw the same performance in 7-Zip's decompression test: both the overclocked and stock Ryzen 7 3700X had the same result.
We also ran JetStream 2 in Google Chrome to check the processor's speed when browsing the web. Again, we got the same score, regardless of whether we used the AMD Ryzen 7 3700X at stock clock speeds or overclocked.
If you want to overclock your processor, there's a high chance that you are a gamer who wants to squeeze the maximum performance possible when playing. That's why we also ran a few games. We used 1080p resolution and the lowest graphic details available for each of them, so that the video card did not slow down the processor.
In Shadow of the Tomb Raider, the CPU Render measurement showed that the overclocked Ryzen 7 3700X generated eight frames less than the factory version.
In Metro Exodus, we saw no difference between the stock version and the overclocked version of AMD Ryzen 7 3700X, as both managed to reach 91 frames per second.
In World War Z, running on Vulkan, the overclocked Ryzen 7 3700X rendered two frames less than its factory version.
We would have liked to showcase the temperatures and power consumption of the overclocked processor, running Prime95. However, in this app, our overclocked AMD Ryzen 7 3700X refused to go through. Each time we tried to run Prime95, the computer would shut down due to critical temperatures reached by the overclocked processor.
However, we were able to monitor the temperatures and power consumption when running Blender - a rendering benchmark that uses the processor at its maximum. To check the processor's temperatures and wattage, we used HWiNFO64. The maximum temperature reached by the Ryzen 7 3700X when using factory clocks was 85 degrees Celsius (185 degrees Fahrenheit), which is under its official maximum temperature of 95 degrees. However, when we overclocked it, it surpassed the official maximum and reached 98 degrees Celsius (208 degrees Fahrenheit). Such temperatures affect the longevity of the processor.
As for the power consumption, the Ryzen 7 3700X drew a maximum of 90 Watts when running Blender. When overclocked, its wattage rose to a significantly higher 121 Watts.
Conclusion: Do not bother overclocking the AMD Ryzen 7 3700X
We are not pleased with the results of our benchmarking experiment because of the following:
- In some benchmarks, we noticed a performance loss from overclocking
- We did see improvements in the rendering benchmarks, where multi-thread performance is essential. However, they were negligible for most users
- The operating temperatures increase a lot, negatively affecting the longevity of the processor
- The power consumption rises a lot
We recommend that you use the AMD Ryzen 7 3700X processor with its default settings. Let the Precision Boost feature do its thing to dynamically boost the operating frequencies, efficiently, whenever AMD's algorithms find it necessary. We made an analysis of Precision Boost and its performance impact, and we were pleasantly surprised with the results. For more details, read: The performance impact of Precision Boost for AMD Ryzen processors.
Our conclusion is that the overall experience you get from the stock AMD Ryzen 7 3700X is a lot better than when overclocking it to 4.25 GHz.
