Hi Andi,

Can you add comments with each model number describing what actual part
it is?
Also, we seem to lack snb/ivb EX part numbers, are those already known?

Yeah, it would be nice if Intel generally documented that whole model
mapping somewhere. For example, I spent some serious time grepping and
searching the net what family 6, model 47 actually is.
I asked hpa at some point about such doc and he said, CPUID doc needs to
get updated.

It would probably be confusing, they have lots of different marketing
names :/ Just think of them as some flavour of Haswell.

They are the same as respective EP (and there is no SNB-EX)

So they're all 'client' chips? Why do they have different model numbers
then?

Urgh, so we cannot differentiate between EP/EX anymore? Does that mean
that the EP chips can be used in 4-8 socket systems?
