Understanding Windows 11 25H2 System Requirements and Hardware Compatibility

Windows 11 25H2: Comprehensive Overview of System and Copilot+ Requirements

The upcoming Windows 11 25H2 (2025 Update) continues to uphold the same basic minimum hardware requirements as its predecessor, Windows 11 24H2. This consistency means that if your device is currently running the earlier version, it should seamlessly upgrade to 25H2 without any compatibility issues.

Newer machines aimed at utilizing the enhanced features, particularly those with Copilot+, will have additional hardware specifications. The Copilot+ PCs will necessitate advanced chipsets such as Snapdragon X Elite, AMD Ryzen AI 300, or Intel Core Ultra 200V, complemented by 16GB of RAM, a 256GB SSD, and a Neural Processing Unit (NPU) capable of at least 40 TOPS to fully leverage AI capabilities.

Essential Hardware Requirements for Windows 11 25H2

To install the Windows 11 25H2, your system must encompass the following hardware specifications:

Processor: 1 GHz or higher with at least 2 cores on a 64-bit processor or System on a Chip (SoC).
RAM: Minimum 4 GB.
Storage: 64 GB or more of available space.
System Firmware: UEFI with Secure Boot capability.
TPM: Trusted Platform Module (TPM) version 2.0.
Graphics Card: Compatibility with DirectX 12 or a later version, along with WDDM 2.0 driver.
Display: HD display of at least 720p resolution and greater than 9 inches in diagonal size.
Connectivity: Internet access and a Microsoft account are required for installation.

While Secure Boot isn’t strictly a requirement, it is strongly advised to have it enabled, especially for modern gaming applications that utilize anti-cheat systems. If you are considering setting up a dual-boot system with a Linux installation, it may be beneficial to disable Secure Boot.

Copilot+ PC Specifications for Windows 11 25H2

For systems to qualify as Copilot+ PCs, the following hardware specifications are necessary:

Processor: Snapdragon X, AMD Ryzen AI 300 series, or Intel Core Ultra 200V series.
NPU: At least 40 TOPS (Trillion Operations Per Second).
RAM: A minimum of 16 GB.
Storage: SSD of 256 GB or larger capacity.
System Firmware: UEFI with Secure Boot enabled.
TPM: Trusted Platform Module (TPM) version 2.0.
Graphics Card: DirectX 12 compliant with WDDM 2.0 driver.
Display: A display with HD resolution (720p or better) and more than 9 inches diagonal.
Connectivity: Internet connection and a Microsoft account for the setup process.

These specifications are mandatory to unlock the latest AI functionalities in Windows 11.

Compatible Processors for Windows 11 25H2

Windows 11 25H2 is compatible with selected processors from Intel, AMD, and Qualcomm:

Intel Processors

The following Intel processors are supported:

8th Gen (Coffee Lake) and newer,
Specific Pentium, Atom, Celeron, and Xeon models,
7th Gen Intel processors are generally supported, but only the 7820HQ variant is specifically recognized.
Core X and Xeon W processors must utilize Declarative, Componentized Hardware Support Apps (DCH) drivers.

AMD Processors

For AMD CPUs, support is limited to:

Second-generation Ryzen and newer (including Threadripper),
Some EPYC and Athlon chips.

ARM Processors

Supported ARM processors include:

Qualcomm Snapdragon 850, 7c, 8c, and 8cx (first and second generations),
Snapdragon X Elite and X Plus,
Microsoft SQ1 and SQ2.

Considerations for Unsupported Devices

While users with unsupported devices may still upgrade at their own risk via ISO files or USB media, they must ensure their systems meet basic requirements, including:

A 64-bit processor with “POPCNT” instruction,
At least 4 GB of RAM,
64 GB storage,
A TPM 1.2 chip, and Secure Boot enabled.

It is crucial to note that the “POPCNT” instruction requirement may hinder the booting process on processors released before 2007.

Additionally, your CPU must support SSE4.2 (for Intel) or SSE4A (for AMD), which enhance multimedia processing capabilities and belong to the Streaming SIMD Extensions (SSE) category.

Summary of Supported Processors for Windows 11 25H2

Intel Manufacturers

8th to 14th Gen, including various models such as Core Ultra, Pentium (Gold and Silver), and select Xeon processors.
Complete list of supported Intel processors.

AMD Manufacturers

Ryzen families 2000 through 9000, along with Threadripper, EPYC, and Athlon series.
Complete list of supported AMD processors.

Qualcomm Manufacturers

Newer Snapdragon models, including 850, 7c, 8c, and 8cx series.
Complete list of supported Qualcomm processors.

The information highlighted is based on the current specifications for installing Windows 11, considering the compatibility between versions 24H2 and 25H2.

Your system must have the following features for the installation and boot process of version 25H2:

64-bit processor with at least two cores.
1 GHz or faster speed.
Compatibility with Intel, AMD, or ARM architectures.
Support for the SSE4.2 instruction set.
Inclusion of the “POPCNT” (Population Count) instruction.

Initially, fulfilling the POPCNT requirement ensured system boot functionality, but now all instructions in SSE4.2 are requisite for compatibility with versions 24H2 and 25H2.

The SSE4.2 instruction set has been part of Intel and AMD architecture for years; hence, it should not impact most users upgrading from existing Windows 10 or Windows 11 installations. Most affected will be a minimal number of individuals attempting to install the OS on extremely outdated hardware.

To verify if your processor encompasses the required instruction set, utilize the CPU-Z app and navigate to the “Instructions” section within the CPU tab.
