Frequently Asked Questions
How Many Cores Do You Need For A Home Server?
4-8 cores are recommended for home servers. However, the type of processors having those cores are more important.
A processor might have 4 CPU cores but the performance won’t be enough for running a home server.
For example, a 4 core Intel Core i3 is less powerful than a 4 core Intel Core i5. Although they have the same number of cores.
The Intel Core i5 has a higher clock speed and can reach greater boost clock speeds when the need arises. Hence, you can’t solely rely on cores when shopping for a CPU for home server.
How Do I Choose A CPU For My Server?
There are two main criteria in choosing a CPU for a home server: core clock speed and number of cores. This combination greatly affects the performance of the CPU.
A CPU might have a very high clock speed and few cores or low clock speed and numerous cores. Both can have equal, less, or greater performance.
In most cases, CPUs with high clock speed and numerous cores are faster in single-core performance. Low clock speeds and numerous cores have the advantage in multi-core performance.
However, this is just an example because you have a CPU with high clock speed and numerous cores or vice versa.
The best way to choose a CPU for your server is to get a shortlist of CPUs you have chosen and compare them using Benchmark programs or websites.
That way you will how they compare to each other and which is best for your needs.
Core Clock Speed
Core clock speed is the measure of how fast a CPU can complete a task in a second. CPU clock speed is measured in GHz.
High-performance CPUs have high GHz so they can process a lot of tasks in a short amount of time.
Number of Cores
Think of a CPU as a house. In this house, we have 5 rooms and each room is a core that makes up the CPU.
In other words, the CPU core is a processor that makes/combine to create the CPU. A CPU might have 1, 2, or multiple cores.
CPUs with a lot of cores (8 and above) are always powerful. A CPU with that number of cores and high clock speed will find an easier time running demanding software.
A CPU might have 4 – 6 cores and still be powerful though they can’t compare to the example listed previously.
Which Processor Is Best For Home Server?
The AMD Ryzen 7 is the best processor for home servers. High clock speeds and numerous cores will easily meet your server requirements and needs.
