Problem is, CPC just means that it can indeed be called a 65W sku, not that it will operate at that tdp in reality.
This is really expected, if 1700 real tdp was indeed 65w, we would be looking at an engineering marvel and a godly undervolting architecture, if such a low clock speed difference could indeeed imply almost 2x tdp difference (1700 at real 65w, 1800x at a little bit over 95w just like CPC tested their 3.6/4 sample).
If that would hold true. Then I would not fear for Intel's desktop and HEDT revenue, I would really start looking at future mobile market share because an architecture that loves to scale downwards in tdp is indeed a wonderful product for the sub 35w tdp enviorment.
PS: This would mean we are looking at another broadwell C type of product and anything above 4.5 would be really difficult, either by a vcore limit or by a power consumption-vrm amperage one.
