The processor that is needed for Windows 11 is a 1 GHz or faster processor with 2 or more cores on a compatible 64-bit processor.
Supported processors for Windows 11 include many of the processors from Intel 8th generation or even equivalent AMD processors.
The minimum processor requirements for Windows 11 is a 1 GHz processor or faster if you prefer, with 2 or more cores on a compatible 64-bit processor.
The minimum RAM or Windows 11 is 4 GB and storage of at least 64 GB or larger and the system firmware for windows 11 should be UEFI, Secure Boot Capable and a Trusted Platform Module or TPM version 2.0 and a graphics card that is compatible with DirectX 12 or later with a WDDM 2.0 driver.
The recommended processors for Windows 11 are Intel 8th generation or newer, like the Intel Core i3, i5, i7 or i9 series or the AMD processor like the Ryzen 3000 series or newer or equivalent AMD processors.
If your computer has an older processor like an Intel 7th generation Core i5, it might not be officially supported and may require a workaround to install Windows 11.
Windows 11 is around 20 GB to 27 GB in size although Windows 11 requires a minimum of 64 GB of storage space for installation, although the initial OS files of windows 11 take up around 20 GB to 27 GB.
The 64 GB storage size for installation is for the windows 11 OS itself as well as ensuring there's enough disk space for future updates, temporary files and drivers.
The amount of GB of RAM that windows 11 uses is around 3 GB, and so to run smoothly it's recommended to have at least 8 GB of of RAM for windows 11, although the minimum amount of RAM needed for windows 11 is 4 GB of RAM.
Windows 11 really needs at least 8 GB of RAM to run smoothly, although the minimum amount of RAM needed to run Windows 11 is 4 GB.
The more RAM you have the smoother windows 11 will run.
The amount of RAM that is enough will depend on your usage and applications of the computer.
If you're just a casual user and do just web browsing, YouTube, checking email and light office work then 8 GB to 16 GB of RAM can be enough.
4 GB of RAM is the minimum needed if running windows 11, although 8 GB of RAM would be better as windows 11 can use most of that 4 GB of RAM which it does on a laptop I have.
I would recommend a minimum of 8 GB of RAM for smooth operation, although having 16 GB of RAM would be even better.
If you're a gamer or video editor then 16 GB of RAM can also be sufficient, but if you do other heavy use tasks or do heavier gaming or 3D rendering then you may need 32 GB to 64 GB of RAM.
64 GB of RAM is overkill for most people and the average user and most gaming.
16 GB of RAM is most often enough RAM for the average user, but 32 GB of RAM is ideal for gaming, video editing, multitasking etc.
Although if you do, do a lot of video editing or 3D rendering, running multiple virtual machines or do any specific high end simulations then 64GB would be needed and be a good idea to have that much RAM.
People that need 64 GB of RAM are video editors, graphic designers that use memory intensive applications like Adobe Photoshop, 3D artists, After Effects or Premiere Pro.
Or if you're a software developer who frequently uses multiple virtual machines for testing or development.
Or if you use some demanding simulations, like flight simulators, for example Microsoft Flight Simulator or if you use your computer for scientific research then you may require 64 GB of RAM or sometimes more.
Although the average user does not need 64 GB of RAM, such as for basic tasks like email, web browsing, watching YouTube, streaming, office applications etc.
And most gamers don't need 64 GB of RAM, although 32 GB of RAM is recommended for the latest AAA games, but 64 GB of RAM dose not provide any significant performance improvements for most gaming scenarios.
And if you only use your computer for tasks like light photo editing, casual gaming, streaming, light video editing, etc then 64 GB of RAM would be overkill.
Although it doesn't hurt to have more RAM than you think you'll need.
But for most people 16 GB to 32 GB of RAM is enough.
