Virtualization allows us to create a virtual version of hardware resources such as networks, storage devices or even an entire physical system.
Now, you may be wondering how is it possible to create a virtual version of an entire physical system? It’s possible due to a technology called Hypervisor. Let’s understand it with an example.
Suppose, you want to run 2 operating systems simultaneously, for that you’ll require 2 different laptops or PCs. Now, every time there is a requirement to run a new OS along with the old ones, you will be forced to buy new hardware. Certainly, this is not a cost-friendly option.
This is where Hypervisors come into play. A hypervisor can divide/isolate the resources of a single PC/Laptop and allows you to install a new OS using the isolated resources. So, on a single Laptop/PC you can run multiple operating systems simultaneously.
The OS running on top of hypervisors are called Virtual Machines (VM) or Guest Machines and the system on which the hypervisor is running is called the host system.
So, if you want to run multiple VMs or allocate more resources to a single VM, you’ll require a lot of resources such as RAM, storage and CPU cores on the host system. Also, to use virtualization technology optimally, it should be supported by the processor.
Don’t worry, all the processors mentioned in this CPU for virtualization list support Virtualization technology.

CPU for Virtualization Buying Guide
What to look for when buying a CPU for Virtualization?
A good CPU for virtualization will be the one that has more number of cores.
You can even run virtual machines on a dual-core or quad-core CPU. However, if you are expecting good performance, then having a minimum of 6 cores will be essential.
AMD vs Intel Which one should you buy for Virtualization?
Both AMD and Intel are leading names in the market for processors. They both offer virtualization features; VT-x, VT-d in Intel CPUs and AMD-V, AMD-Vi in AMD CPUs.
AMD uses No Execute (NX) bit and Intel uses Execute Disable (XD) bit to prevent the execution of certain types of code in the protected areas which in turn protects the VM from malware.
The best way of choosing the right CPU for virtualization is to look at the hypervisor you are planning to use. Some Hypervisors might have good support for AMD processors, others for Intel.
What about the other components like RAM and Storage for Virtualization?
Virtualization requires other resources like memory and storage to run virtual machines.
Apart from CPU, running Virtual Machines will require a significant of RAM. The exact memory required for virtualization will depend on your use case. However, having a minimum of 16 GB RAM will be a good starting point.
32 GB RAM is recommended for a smooth virtualization experience. If your computer allows expansion to 32 GB, then you can go for it as the need arises.
Once again, the amount of storage required will depend on your particular use case. However, it is recommended to have a Solid State Drive (SSD) over the traditional spinning disks (HDD) for better performance.
Since SSDs are faster and more power-efficient, they have an advantage over HDDs while running multiple virtual machines that may require a significant amount of read/write operations.
Depending on your use case and budget you can choose any of these CPUs for your virtualization needs. Moreover, the CPUs mentioned in this list are not only good for virtualization but for any general usage – like gaming, streaming, editing etc.
