Windows 11指日可待，而且微软(Microsoft)确保为任何想要升级的人提供安全要求。这意味着数百万Windows 10用户将不得不购买新计算机才能体验新操作系统所提供的功能。
您的计算机需要支持可信平台模块(Trusted Platform Module)( TPM 2.0 )。但是，从硬件的角度来看，只有英特尔(Intel)方面的第 8代及更高版本支持TPM 2.0。至于AMD，只有Zen 3及更高版本。
如果您想了解更多信息，请阅读我们关于支持 Windows 11 的芯片组和主板(Chipsets and motherboards that support Windows 11)的文章，以更深入地了解所需的硬件类型。
什么是TPM（可信平台模块(Trusted Platform Module)）？
可信平台模块(Platform Module)或TPM是存储加密密钥的专用芯片。它充当支持它的设备的端点安全性。
当涉及到在硬件阶段存储加密密钥时，这就是TPM发挥作用的地方。许多安全研究人员认为，最好从硬件级别而不是软件级别存储安全密钥，以更好地阻止黑客。整个科技行业都在采用TPM，因此，微软(Microsoft)不希望落后，尤其是考虑到我们现在已经深入到数字时代。
什么是PTT（平台信任技术(Platform Trust Technology)）？
PTT提供离散TPM 2.0的功能。英特尔 PTT(Intel PTT)是Windows 11/10使用的凭据存储和密钥管理的平台功能。我们应该指出，PTT是一项英特尔(Intel)技术。
TPM和PTT之间的区别
Platform Trust Technology旨在与Trusted Platform Module一起使用，因此没有真正的 vs. 因为它们不能完成相同的整体任务。我们在下面解释更多。
平台信任技术(Platform Trust Technology)与可信平台模块(Platform Module)
首先，我们应该指出PTT和TPM是不同的技术，但它们是相辅相成的。你看，如果你的电脑支持TPM 2.0 ， PTT就在那里，但它不包含专用芯片。我们知道这一点是因为许多CPU(CPUs)从固件级别支持TPM 。
英特尔(Intel)创建PTT以帮助在没有专门支持的计算机上启用TPM ，据我们所知，它工作得很好。(TPM)该技术创建于 2013 年；因此，我们预计至少配备第 4代Intel CPU(Intel CPUs)的计算机可以通过PTT运行Windows 11。至少，我们是根据理论提出这一点的，因为我们自己还没有测试过。
那么，AMD呢？好吧(Well)，我们了解到Zen CPU(Zen CPUs)配备了PTT的替代品，称为fTPM。

您的计算机是否支持 TPM？
从我们收集到的信息来看，2015 年之后的计算机即使没有安装专用芯片也应该支持TPM 。现在，这就是PTT发挥作用的地方。英特尔(Intel)从其第 4 代芯片开始将此技术添加到计算机中。
借助这项技术，可能会有更多的人有机会下载和安装 Windows 11，而不是之前想象的。
如何判断您的计算机是否支持TPM 2.0
有多种方法可以检查 TPM 芯片的可用性(ways to check TPM chip availability)。但是，您应该知道它应该在硬件级别启用，以便像Bitlllocker(Bitllocker)这样的安全软件安全可以使用它。
- 使用 TPM 管理
- 在 BIOS 或 UEFI 中启用它
- 在设备管理器(Device Manager)中使用安全节点(Security Node)
- 使用 WMIC 命令。
您可以使用 Windows 11 中的 TPM 诊断工具(TPM Diagnostics Tool in Windows 11) 来查找系统的可信平台模块(Trusted Platform Module)芯片信息。
TPM vs PTT: What are the main differences between them?
Windows 11 is right around the corner and, and Microsoft made sure to include security requirements for anyone who wants to upgrade. This means millions of Windows 10 users will have to purchase new computers in order to experience what the new operating systems have to offer.
Your computer will need to support Trusted Platform Module (TPM 2.0). However, from a hardware standpoint, only the 8th generation and up from the Intel side of things support TPM 2.0. As for AMD, only Zen 3 and up.
If you want to learn more, please read our post on Chipsets and motherboards that support Windows 11 to get a deeper understanding of the type of hardware required.
What is TPM (Trusted Platform Module)?
Trusted Platform Module or TPM is a specialized and dedicated chip that stores cryptographic keys. It acts as endpoint security for the devices which support it.
When it comes down to storing encryption keys on the hardware stage, that is where TPM comes into play. Many security researchers believe it is best to store security keys from a hardware level instead of software to keep hackers at bay better. The entire tech industry is adopting TPM, and as such, Microsoft does not want to be left behind, especially seeing as we are now knee-deep in the digital age.
What is PTT (Platform Trust Technology)?
PTT offers the capabilities of discrete TPM 2.0. Intel PTT is a platform functionality for credential storage and key management used by Windows 11/10. We should point out that PTT is an Intel technology.
Difference between TPM and PTT
Platform Trust Technology is designed to work with Trusted Platform Module, so there are no real vs. since they do not work to accomplish the same overall task. We explain a bit more below.
Platform Trust Technology vs. Trusted Platform Module
To begin, we should point out that PTT and TPM are different technologies, but they complement each other. You see, PTT is there if your computer supports TPM 2.0, but it does not contain a dedicated chip. We know this because many CPUs have TPM support from a firmware level.
Intel created PTT to help with enabling TPM on computers that do not have dedicated support, and from what we can tell, it works quite fine. The technology was created back in 2013; therefore, we expect computers with at least the 4th generation Intel CPUs to run Windows 11 via PTT. At least, we are making this point based on a theory since we haven’t tested it ourselves.
So, what about AMD? Well, we have learned that Zen CPUs come packed with an alternative to PTT known as fTPM.

Does your computer support TPM?
From what we have gathered, computers after 2015 should support TPM even if they do not have a dedicated chip installed. Now, this is where PTT comes into play. Intel added this technology into computers starting from their 4th generation chips.
With this technology, more people might get the chance to download and install Windows 11 than previously thought.
How to tell if your computer supports TPM 2.0
There are multiples ways to check TPM chip availability. However, you should know that it should be enabled at the hardware level so that security software security like Bitllocker can use it.
- Using TPM Management
- Enable it in BIOS or UEFI
- Using the Security Node in Device Manager
- Using WMIC command.
You can use TPM Diagnostics Tool in Windows 11 to find out the Trusted Platform Module chip information of your system.
