The overall performance doesn't depend on the processor only. It also depends on another component like how much RAM is there, how fast HDD can transfer the data, and how the components are configured with the operating system.
Because of the SSD, the Avita Pura acts way faster despite the fact it doesn't have the more powerful R3 3300U processor.
As most of the laptops in this segment come with HDD, you might feel some lag or stutter here and there.
