Experts generally compare processors based on their performance and efficiency, and buyers might also want to check if they have more processing power than they need. Benchmarks can help companies make the most of their investments.
Processors have ratings in terms of how many instructions they can compute per minute, and this number is helpful for determining how much data processors can handle. However, some processors can do more work per instruction cycle than others, so experts often rely on benchmarks to rate processor performance. Benchmarks can vary depending on chore at hand; a processor that's good at encoding video, for example, might perform poorly when serving websites. Specific benchmarks are more efficient than general ones.
Another key factor to consider is how much energy the processor uses. ARM-based processors use relatively little electricity and are less expensive than their x86-64-based counterparts from AMD and Intel, but they aren't as powerful per clock cycle. However, the lower operating cost of ARM chips may make them a better option for some use cases.
It's also important to consider software compatibility. While Linux distributions and other popular server operating systems often provide ARM support, certain programs might not offer ARM versions. Popular open-source programs typically compile and run on ARM processors, but proprietary programs might not.
