Sure, but as you say yourself, the 8180 isn't the same budget at all, so I excluded it from your price comparison. Also, it's not a competitor to the 1950x. I guess in the end it all depends on what you need to do. Your need seems to be maximum performance, why go for the best "compromise" CPU and then criticize their choice? Clearly you should go for either of the 3 recommended CPU for performance. (which are also better for PCIe lanes and memory, but have a poor performance price ratio).

if it is about budget, or performance per $, surely you'd be buying Xeon from ebay. you don't lose anything as the likelihood of having a dead processor 18 months from now is pretty much 0, no warranty required.

if it is about PCIE lanes, you should at least be buying dual socket systems, that gives you more PCIE lanes than 1950x.

if it is about memory, well, 1950x is limited to 8 DIMMs.
