[SOLVED] Intel 10400f Part Number

[tallemeister]

Hi everyone. I hope everyone is having a nice day.

So I ordered an i5 10400f CPU without the box. When I was checking the site I ordered there were 2 different 10400fs, with a price difference of 15euros. So I ordered cheaper one without thinking too much. They were both without box and obviously had exact specs because they're the same models right?
Guess not. I checked the site again and noticed they have different serial numbers; one with CM8070104290716 (cheaper one) and another one with CM8070104282719.

I'm actually not much worried about performance difference but how much difference there could be? Anything noticable?

Thanks in advance!

I would expect different serial numbers between any two CPUs. Intel identifies those as equivalent.

CM80701042 are a complete match. The remaining numbers are likely a manufactured time and location, if not just an outright serialization.
