Question Stepping on i7 3770K CPU

[The Fat Fish]

Hi all,

I know this is regarding an old CPU but I hope someone can help. I am looking to buy an i7 3770K processor (I know, odd) and want to know more about steppings. I know that there are at least 4 steppings for this CPU (A, B, C and D). So far I have read that:

A - Less voltage, more heat.
B - More voltage, less heat.
C - ?
D - ?

So what are the differences with the C and D versions?

Thank you in advance for your help.

Looks like 2 of the steppings might have been engineering samples:

Thank you. So these stepping would almost be pre-production?

Yep, quality control or pre-production samples.
