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. Indeed, 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.

Memory (RAM)

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 (or more) is recommended for a smooth virtualization experience. If your computer allows RAM expansion, 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.

Frequently Asked Questions

What is the importance of the CPU in virtualization?

The CPU plays a crucial role in virtualization as it is responsible for executing virtual machine instructions and managing multiple virtual environments simultaneously. A powerful and modern CPU with support for virtualization technologies, such as Intel VT-x or AMD-V, ensures efficient resource allocation, reduced latency, and better overall performance for virtualized workloads.

How do I determine if my CPU supports virtualization?

To check if your CPU supports virtualization, you can review the specifications on the manufacturer’s website or consult your CPU’s user manual. Additionally, you can use software tools like “CPU-Z” to identify if your CPU has virtualization support (Intel VT-x or AMD-V). It is essential to ensure that hardware virtualization is enabled in the BIOS/UEFI settings to fully utilize this capability.

Can I use any CPU for virtualization, or are there specific requirements?

While most modern CPUs come with hardware virtualization support, not all CPUs are suitable for intensive virtualization workloads. For optimal virtualization performance, it is recommended to choose a CPU with multiple cores/threads and higher clock speeds. CPUs with features like Intel Hyper-Threading or AMD SMT (Simultaneous Multi-Threading) can significantly enhance virtual machine responsiveness and multitasking capabilities.

Should I prioritize single-core or multi-core performance for virtualization?

In virtualization, multi-core performance is generally more critical than single-core performance. Virtualization platforms can efficiently distribute workloads across multiple cores, benefiting from increased parallelism. Having more cores allows you to run multiple virtual machines simultaneously without causing significant bottlenecks. However, a balance between core count and individual core performance is ideal for a well-rounded virtualization experience.

Are there specific CPU features I should consider for nested virtualization?

Nested virtualization allows running virtual machines inside virtual machines. To enable nested virtualization, your CPU must support Intel VT-x or AMD-V virtualization technologies at the host level. Additionally, you should ensure that nested virtualization is supported and enabled in your hypervisor settings, as well as within the guest virtual machines. Nested virtualization is particularly useful for testing and development scenarios within virtualized environments


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 suitable for virtualization but for any general usage – like gaming, streaming, editing etc.
