If there are four digits, there are second or later generations

For example

Intel core i3.,,,, 803

That is, if three digits come after i3, it means first generation

Intel core i3.,,,, 2304

In this example, i3 is followed by four digits, so this is the second generation

Similarly

Intel core i3.,,,, (3)405

Inter core i3.,,,, (4)505

These two examples also have four digits, but in the first example, the starting digit is 3, so it is the third generation

In the second example, the starting digit is 4, so the fourth generation
