I just realized there is a typo in the above table,...
The current Sandy Bridge-E lineup is as follows:
Core i7 3960X
Core i7 3970X
Core i7 3930K
Core i7 3820
Supposedly there is a pending Core i7 3980X with 8 core / 16 threads but that is the type of thing you have to see to believe. Anyway, in the above table the entry level Core i7 3820 is listed as a Core i7 3820K
which is incorrect in name and indication as it isn't a fully unlocked processor.
However, in the above chart, its successor the Ivy Bridge-E Core i7 4820K
has the "K" suffix as well. In this case we don't know if this is in error just like with the 3820. Although, if you look at the leaked document here:
»www.techpowerup.com/182238/Intel ··· led.html
You'll notice that the current Sandy Bridge-E Core i7 3820 correctly has no "K" suffix but the upcoming entry level Ivy Bridge-E Core i7 4820K does have the "K" suffix.
Still don't know for sure but it would be an improvement if the entry level Ivy Bridge-E processor was unlocked in the same way as the rest of the lineup.
