Hardware has two primary uses — “home” and “enterprise.” Intel Xeon CPU
Home CPUs are designed to perform tasks quickly, such as games, streaming, video editing, and so on. Expected tasks should be done quickly.
Enterprise CPUs tend to be more focused on performing multiple tasks reliably. Another answer mentioned ECC memory, which is a good example of reliability. Powerful CPUs can also handle large amounts of memory, and most can run on two or four CPU systems.
Older Xeon systems may be very popular as cheap gaming gear, but they tend to miss out on more modern features such as native video transcoding.
