vCore?
vCore?
They're using a different way to describe performance. Azure says their processors have 80 vcores, but that doesn't mean each core is 80 GHz. Instead, it's a way to say the total processing power available. If your system is running at 4.5 GHz per core, you can check the specs to see how many cores are actually active and what speed they're running at. It's like saying you have a bunch of workers, each doing a certain amount of work, not just one big machine.
It seems to refer to a thread, as the Task Manager in Windows also labels it as logical processors. Checking the Azure documentation confirms this connection, and hyperthreading is discussed alongside vCore.
Azure provides 80 virtual cores under the name vcores. The vCore setting in your BIOS refers to the voltage supplied to the CPU.
vCore is a virtualized CPU Core/Thread designed for flexibility. It isn't reserved and might not be present on your system. For users, it means you're getting enough virtual memory to manage 80 threads simultaneously. Performance depends on other virtualized tasks and their load at the same time.
