Yes, I said that.

Irrelevant for KNL replacement that I am discussing.
Also, as I said above, I don't propose Haswell or Skylake like uArch, but something with scalar part of the core more like Bridges. Scalar part 1 *Bridge-like core shouldn't be much bigger than a a scalar part of pair of *Mont-like cores on the same process.

How do you know the TDP Cherry Trail?
I was under impression that Intel only published SDP (2W) and for TDP you have to be an OEM and to sign NDA.

The post was not about tablets. It was about relative merits of two families of Intel cores for HPC-oriented Xeons. Tablet chips were mentioned only as the best available public source for comparisons of the cores.
