Intel's current i5s and i7s, any other product range quirks?

Sorry for the unhelpful topic title, but what I mean is, for example, IIRC the i7-4770k doesn't support vt-d yet the 4770 does.

I'm mostly aware of the other facets of their range such as the 'K' to denote an unlocked multiplier IIRC.

4790K supports VT-D. 4770K was replaced.

All the info you ask for can be found here:

I believe i3's support ECC if paired with a server chipset, while i5's and i7's do not. Pentiums and Celerons are missing several instructions, the most important of which is arguably AVX.
