Best CPU for Virtualization in 2021

all about the best processors for virtual infrastructure

Virtualization is an advanced process that helps us create virtual networks, servers, storage capacities rather than having a physical one. Also, it is one of the most cost-effective processes in the field of IT. CPU Virtualization is a more reliable way to handle multiple virtual resources at the same time. And choosing the right CPU for virtualization depends upon the features that want in your virtualization infrastructure. One of those features is the execute disable (XD) and no execute (NX) that prevent a CPU from running code in areas where there are more chances of malware attacks.

Both Intel and AMD CPUs are equipped with these execution bits along with LAHF and SAHF commands for better allocation of resources. Intel uses VT and AMD goes with AMD-V virtualization technology to take care of multiple virtual hosts connected to a single machine. And in this guide, we’ve rounded up some of the best CPUs for virtualization that handle huge workloads and are compatible with software like VirtualBox, VMWare, and Parallels.

Whether it’s about the Client-Side Virtualization, Virtual Desktop Infrastructure, or OS Streaming, these processors handle all these functions without any hassle.

The Core i5 8600K is one of those CPUs that have been a hot talk on online forums. Not only this CPU gives you unbeatable performance in gaming but also in enterprise-related tasks as well. If you going after a mid-range virtual machine setup, the Core i5 8600K will definitely save you few bucks without compromising on the performance.

Just like the Core i9 9900K, the 8600K also comes with security features like Secure Keys and Boot Guard. However, both CPUs are great at handling virtualization functions but the Core i9 9900K is 42% faster than the Core i5 8600 in virtualization.

if you want to deal with Linux virtual machines, then this CPU is great to handle that without any hassle. The Intel Virtualization technology on the top makes this processor handle multiple workloads across virtual infrastructures. This CPU has multiple cores that can run multiple VMS without any hassle. Just make sure you install the right CPU cooler with i5 8600K to keep the temperatures minimal.

Intel Core i7-7820X – A High End Processor for Virtualization Functions

Reasons to Consider

The Core i7-7820X is a high-end CPU with eight cores and 16 threads. Although this processor is expensive as compared to others on the list, it makes your virtual machine future-proof in performance.

Make sure you have plenty of ram if you use a dual-core CPU for virtualization. It’s better if you go for at least 16GB of DDR4 ram in this case. If you are running more than 3VMs at a single time, we recommend you a CPU with more cores like AMD Ryzen 5 2600X or Core i9 9900K.

How to Pick the Best CPU For Virtualization

A CPU that isn’t a right fit for the virtualization infrastructure can increase downtime and negatively affect the overall performance. Therefore it is important to choose the most compatible CPU for your virtual machine. Here are some of the key factors to keep in mind before buying a CPU.

AMD or Intel

AMD and Intel are the two key players in the market when it comes to going after a CPU. It is important to note the specific requirements of your virtual network before choosing between an AMD or Intel CPU.

Intel offers virtualization features like VT-x & VT-d whereas AMD comes with AMD-V and AMD-Vi to take care of the virtual environment. However, Intel and AMD offer the same NX/XD bits features that prevent the processor from executing a code in restricted areas. Depending upon your virtual networks’ preferences, you have to choose in-between the Intel and AMD CPUs.

Don’t overlook at Hyper-threading

The next step is to identify which features of your CPU are more worthy in virtualization. Many people see hyper-threading as an important factor in improving the performance of virtual machines, this is wrong. Hyper-threading isn’t the only factor that helps in boosting the performance of your processor. The core that has only one execution engine can trigger delays in resource allocation.

Therefore, instead of looking at hyper-threading, it’s worth spending money on a CPU that comes with more cores. A CPU with more than 4 cores is ideal for virtualization as it can equally distribute the workload on all cores, thus reducing delays.

Minimizing with SLAT

The software used for virtualization can reduce the available resources for VMs. SLAT (Second Level Address Translation) is a feature that common in modern Intel and AMD CPUs to minimize the overhead and improves the virtualization performance by adding a cache. If the information already exists in that cache, the system resources aren’t needed for any further translation.

vCPU to VM Workload Ratio

Every virtual function or application has a seperate computing requirement inside a virtual infrastructure. Some VMs need just one CPU to work properly whereas others need more than two vCPUs. For instance, if an application needs one physical, assign one vCPU to see if it works or not. If the application shows lag or delays, allocate two vCPUs and then monitor the performance.
