We know AMD's CPU have better power consumption
Yes
we know they have better thermals
To a point, stock for stock this is of no importance. Once we open the envelope, things get interesting and a barrier is often reached on mainstream cooling on both systems. The difference being, there is a lot more benefit to breaching this barrier on SKL-X, as it actually overclocks quite well.
They have 20 more PCIe lanes wich for workstations does matter, we know they have ECC compatible memory where as the i9's don't, that matters for servers
So you are saying you need in excess of 60 PCIE lanes for a workstation? Perhaps you can find me some evidence of multitudes of users asking for more than 40 lanes on an enthusiast platform. ECC support, is a bonus, yes. But then will you buy ECC memory, or will you overclock it? No. On the subject of memory, you're aware SKL-E is capable of 4133Mhz in quad channel, quite a bit higher than TR.
We know in heavy workloads the 1950X is faster.
Faster than? You'll need to be more specific. A 1950X is faster than a 7900X in heavily multithreaded work loads. Of course it is, it has 6 more cores and 12 more threads. Does a bear crap in the woods? If we move up Intel's revised SKU ladder, we'll find a 16 core part there, too. And guess what, it's faster.
There are plenty of professional reviewers out there who like the feel of threadripper.
Not sure what liking the feel means, I don't tend to feel my CPU too much. Once it's in, it's in. Ryzen offers exceptional value, the ultimate question I'm asking you is, is it faster? No. Not when we look at the entire product stack. This shouldn't be a surprise to anyone given what we know about Zen.
Encompassing everything, what part of any of this results in Intel quaking in their boots? I can only think that you're fixating on one particular point, as that simple isn't the case. If it was, I'd be buying TR right now. As would all of 8-Packs customers.
