当您寻找要购买的新计算机处理器(computer processor)时，您会偶然发现CPU 基本时钟或 CPU(CPU base clock or CPU)提升速度等技术细节。你有没有(Did)想过这意味着什么？虽然所有处理器的基本时钟(base clock)（工作频率）都在几千兆赫范围内，(Gigahertz)但现代处理器也宣传更高的涡轮增压(turbo boost)速度。无论您是在研究AMD 还是 Intel 处理器，它们都以(AMD or Intel processors)涡轮增压(turbo boost)时钟炫耀。以下是Turbo Boost在处理器方面的含义：
处理器基本时钟是多少？
您应该首先了解处理器（CPU - 中央处理单元(Processing Unit)）的基本时钟(base clock)是什么。基本时钟是处理器的标准速度或工作频率。它以千兆赫为单位，告诉你它在一秒钟内可以执行多少亿次计算(The base clock is a processor's standard speed or operating frequency. It is measured in Gigahertz, and tells you how many billions of calculations it can perform in one second)。
在计算机的早期，处理器仅以其基本时钟(base clock)（频率）运行，这意味着它们具有固定的速度，不会上升或下降。这也意味着比较处理器以找出哪个更快是相当容易的。通常，具有较高时钟的处理器比具有较低时钟的处理器快。例如，3 GHz 处理器(GHz processor)比 2.5 GHz 处理器快，尽管(GHz processor)处理器架构(processor architecture)或高速缓存内存(Cache memory)量等其他因素可能会改变平衡。
什么是处理器涡轮增压时钟(processor turbo boost clock)？
然而，现代处理器也有第二个涡轮增压时钟(turbo boost clock)，这使事情变得有点复杂。涡轮增压时钟是(turbo boost clock mean)什么意思？嗯，现在AMD 和 Intel(AMD and Intel)都创建了可以根据你在做什么来调整速度的计算机处理器。涡轮增压时钟是处理器可以运行的最大速度(The turbo boost clock is the maximum speed at which a processor can run)。
您可以说，无需您干预即可自动加速、超频的处理器。例如，具有3.6 GHz标准(GHz)基础频率(base frequency)和4.6 GHz涡轮增压时钟(turbo boost clock)的处理器，例如Ryzen 7 3700X，在运行要求苛刻的应用程序或游戏时可以运行在 4.6 (apps or games)GHz，但只能运行在 3.6 GHz在剩下的时间里。处理器自行处理运行速度。
为了使处理器达到其最高额定涡轮增压时钟(turbo boost clock)，必须满足几个条件：
-
功率：(Power:)因为更高的速度需要更多的能量，所以您的主板必须能够提供处理器在其涡轮增压频率(turbo boost frequency)下运行所需的功率。
-
温度：(Temperature:)处理器从主板汲取的电量越高，意味着处理器的热量也会越多。因此，CPU必须具有良好的冷却系统(cooling system)，可以将其温度保持在范围内。否则，如果温度上升太多，处理器将进入节流模式。这意味着它会自动降低频率以保护自己免受过热造成的损坏。
-
利用率：(Utilization:)要达到其额定涡轮增压速度(boost speed)，您的处理器必须有这样做的理由。如果您的应用程序或游戏(apps or games)不需要比基本时钟(base clock)更高的速度，则处理器没有理由增加其涡轮增压时钟(turbo boost clock)。此外，如果不是您的处理器的所有内核都在积极使用，则没有理由激活turbo boost。
此外，现代处理器具有多个内核，通常少至 2 个内核，多至 16 个内核。您可能会认为为您的CPU宣传的涡轮增压速度(turbo boost speed)意味着它可以在其所有内核上达到最大频率，但情况可能并非如此。有些处理器只能在其一个、两个或更多内核上达到它，因此了解您的CPU可以提供什么更加复杂。但是，您可以确定的一件事是，您的 CPU 上至少有一个内核可以(at least one of the cores on your CPU can reach the turbo boost speed)在任何给定时间达到涡轮增压速度。最常见的情况是当多核CPU达到涡轮增压时(turbo boost)它的两个内核上的速度，但其他内核使用较低的时钟。
为了让事情变得混乱，制造商对涡轮增压(Turbo Boost)的命名不同
AMD 和英特尔(AMD and Intel)都拥有控制其处理器基础和涡轮增压速度(base and turbo boost speeds)的技术。对于他们最新系列的计算机处理器（Ryzen 2000 和Ryzen 3000） ， AMD将其称为Precision Boost 2。您可以在下面的屏幕截图中看到有关它的一些详细信息。
从第二代的Intel Core i5 和 i7开始， (Intel Core i5 and i7)Intel使用Intel Turbo Boost Technology v.2.0，而对于最新的Core i7和 i9 处理器，它使用Intel Turbo Boost Max Technology v3.0。
为什么涡轮增压时钟很重要(turbo boost clock matter)（好处）？
拥有可以加速(turbo boost)的处理器的主要好处是它可以使您的计算机在重负载下运行得更快(makes your computer faster under heavy load)。如果您运行视频游戏(video game)或要求苛刻的应用程序，您的处理器会自动增加其加速时钟(boost clock)并为您提供最佳性能。这意味着在最重要的时候有更好的性能。
此外，涡轮增压是一个完全自动的过程(turbo boost is a completely automatic process)：您的处理器自动超频，无需您的任何干预。它可以正常工作，因此每个人都可以从中受益，无论是没有计算机经验的(computer experience)家庭用户(home user)，还是使用需要大量处理能力的(processing power)企业应用程序(enterprise apps)的专业人士。
如何查看您的处理器是否处于涡轮增压模式(turbo boost mode)
您如何查看您的处理器是否在涡轮增压模式下运行(turbo boost mode)？您可以使用可以监控您的CPU的专用应用程序，例如CPU-Z，或者您可以使用Windows中的任务管理器。(Task Manager)
如果您不想使用第三方应用程序，请启动任务管理器(Task Manager)。您可以通过按键盘上的Ctrl + Shift + Esc键快速打开它。然后转到性能选项卡并选择(Performance tab and select) 窗口左侧的CPU 。在右侧的利用率图(utilization graph)下方，您可以看到有关处理器的一些详细信息和实时信息。其中，Base speed告诉你处理器的基本时钟是多少， (base clock)Speed告诉你它的当前速度。如果Speed (2)值高于Base speed (1)，则意味着您的处理器正在以涡轮增压模式运行(turbo boost mode). 以下是我们在AMD Ryzen 7 2700 处理器以涡轮增压模式(turbo boost mode)运行时看到的情况：
以下是我们其中一台笔记本电脑的英特尔酷睿(Intel Core)i7-7700HQ 处理器示例：
同样， CPU-Z(CPU-Z)等第三方应用程序可以实时显示处理器的当前速度。如果您正在运行要求苛刻的应用程序或游戏(demanding app or game)，并且当前处理器频率(processor frequency)高于其基本时钟(base clock)，正如其制造商所宣传的那样，那么这意味着您的CPU正在加速(turbo boost)运行。

What is Turbo Boost or Precision Boost when it comes to processors?
When you look for а new cоmputer processor tо buy, you stumble upоn technicalities such aѕ CPU base clock or CPU boost speed. Did you wonder what that means? While all processors have a baѕe clock (opеrating frequency) that is in the range of a few Gigahertz, modern processors also advertise higher turbo boost speeds. Whether you're looking into AMD оr Intel processors, all of them show off with their turbo boost clocks. Here is what Turbo Boost means when it comes to processors:
What is the processor base clock?
You should first understand what the processor (CPU - Central Processing Unit) base clock is. The base clock is a processor's standard speed or operating frequency. It is measured in Gigahertz, and tells you how many billions of calculations it can perform in one second.
In the early days of computers, processors only ran at their base clock (frequency), which meant that they had a fixed speed, that did not go up or down. It also meant that comparing processors to find out which was faster was fairly easy. In general, a processor with a higher clock was faster than a processor with a lower clock. For example, a 3 GHz processor was faster than a 2.5 GHz processor, although other things such as processor architecture or the amount Cache memory could alter the balance.
What is the processor turbo boost clock?
Modern processors, however, also have a second turbo boost clock, that complicates things a bit. What does the turbo boost clock mean? Well, both AMD and Intel nowadays create computer processors that can adjust their speed depending on what you are doing. The turbo boost clock is the maximum speed at which a processor can run.
You can say that processors that can turbo boost, overclock themselves, without your intervention. For example, a processor that has a standard base frequency of 3.6 GHz and a turbo boost clock of 4.6 GHz, such as the Ryzen 7 3700X, can run at 4.6 GHz when you are running demanding apps or games, but only runs at 3.6 GHz in the rest of the time. The processor handles the running speed on its own.
In order for a processor to reach its highest-rated turbo boost clock, a few conditions have to be met:
-
Power: Because a higher speed requires more energy, your motherboard must be able to deliver the power necessary for the processor to run at its turbo boost frequency.
-
Temperature: The higher amount of power drawn by the processor from the motherboard means that processor also heats more. Thus, the CPU must have a good cooling system that can keep its temperatures in range. Otherwise, if the temperatures go up too much, the processor goes into throttle mode. That means that it automatically lowers its frequency to protect itself from damage caused by overheating.
-
Utilization: To reach its rated turbo boost speed, your processor must have a reason to do that. If your apps or games do not need more speed than the base clock, the processor has no reason to increase to its turbo boost clock. Also, if not all the cores of your processor are actively used, there is no reason to activate turbo boost.
Furthermore, modern processors have more than one core, usually going from as few as 2 cores and up to 16 cores. You might be tempted to think that the turbo boost speed advertised for your CPU means that it can reach that maximum frequency on all of its cores, but that might not be the case. Some processors can reach it only on one, two or more of their cores, so understanding what your CPU can offer is even more complicated. However, one thing that you can be sure of is that at least one of the cores on your CPU can reach the turbo boost speed at any given time. The most common situation is that when a multi-core CPU reaches its turbo boost speeds on two of its cores, but the other cores use lower clocks.
To make things confusing Turbo Boost is named differently by manufacturers
Both AMD and Intel have technologies that control their processors' base and turbo boost speeds. For their latest series of computer processors (Ryzen 2000 and Ryzen 3000) AMD calls it Precision Boost 2. You can see a few details about it, in the screenshot below.
Starting with Intel Core i5 and i7 from the second generation, Intel uses Intel Turbo Boost Technology v.2.0, and for the latest Core i7 and i9 processors, it uses Intel Turbo Boost Max Technology v3.0.
Why does the turbo boost clock matter (benefits)?
The main benefit of having a processor which can turbo boost is that it makes your computer faster under heavy load. If you run a video game or a demanding application, your processor automatically increases its boost clock and gives you the best performance it can. That means better performance when it matters most.
Furthermore, turbo boost is a completely automatic process: your processor overclocks itself, without needing any intervention from you. It just works, so everyone gets to benefit, whether a home user with no computer experience or a professional who works with enterprise apps that require heavy processing power.
How to see if your processor is in turbo boost mode
How do you see if your processor runs in turbo boost mode? You can use a specialized app that can monitor your CPU, like CPU-Z, or you can use the Task Manager from Windows.
If you prefer not to use third-party apps, launch Task Manager. You can quickly open it by pressing the Ctrl + Shift + Esc keys on your keyboard. Then go to the Performance tab and select CPU on the left side of the window. On the right side, under the utilization graph, you see some details and real-time information about your processor. Among them, the Base speed tells you what the base clock of your processor is, and Speed shows you its current speed. If the Speed (2) value is higher than the Base speed (1), it means that your processor is running in turbo boost mode. Here is what we see when an AMD Ryzen 7 2700 processor runs in turbo boost mode:
And here's an example of an Intel Core i7-7700HQ processor from one of our laptops:
Similarly, third-party apps such as CPU-Z can show you the current speed of your processor in real time. If you are running a demanding app or game, and the current processor frequency is higher than its base clock, as advertised by its manufacturer, then it means that your CPU is running in turbo boost.
