What is 10 cores equal to?

Could you please clarify for me, what exactly does it mean when we say "10 cores equal to"? I'm trying to understand the concept in terms of computing power or performance. Is it referring to the number of processors in a system, or is it something else entirely? Could you possibly provide a real-world example to help me visualize what 10 cores equate to in terms of functionality and efficiency? Additionally, how does having 10 cores impact the overall speed and multitasking capabilities of a device or machine? I'm interested in knowing how this translates into practical use cases, especially in the realm of cryptocurrency and finance where high-performance computing is often crucial. Thank you for your assistance.
