Quietrob - that was pre-Zen AMD. The chiplet design + Infinity Fabric means higher performance and much higher chip yields. The consumer series of chips (Ryzen Series), outside of the 3950x, are the worst performing silicon. Each Zen 2 chiplet has 8 cores. Defective cores are turned off and used to make Ryzen 5, 7, 9 and 12 core Threadripper) series of chips.

The best binned chiplets go into Eypc server chips (That is where AMD makes the most money). The 2nd best binned chiplets go into Threadripper HEDT (High End DeskTop), where AMD also make lots of money. The 3rd best binned chiplets go into the Ryzen 9 (3950x aka "baby threadripper") This is AMD's Halo product for consumers. Everything else goes into Ryzen 5, 7 and 12 core Ryzen 9 chips.

Intel does the same - all chips are built to one design, and defective cores are turned off.

Stick a fork in Intel - they are done (for the next few years - they are having their Bulldozer moment). The 1st iteration of their 10nm process simply didn't work. Intel has had to start all over, and design a completely new architecture. In the meantime, they can't even pump out enough 14nm++++++++ (to infinity and beyond) to meet current demand. They will have chip shortages (of old cpus) until 2nd half of 2020.

The Zen architecture out performs anything Intel has. More importantly, AMD has a 15 month development cadence. In January, the last Zen 2 based CPU launches - the X3990x - 64 cores, 128 threads at over 3.0Ghz, all cores.

Zen 3 is a new architecture - and it is already sampling. It will launch at the end of next year, and it will show somewhere between a 10 - 15% IPC (Instructions per clock) increase over Zen 2. And AMD is already working on Zen 4 (which may have SMT 4 - 4 threads per core. So a Zen 4 Ryzen could start with a 4 core/16 thread CPU - wouldn't that make rendering easier)

Intel has ceded the HEDT to AMD. Their latest, i9 processor, the the i10980xe (18 cores/32 threads), was obsolete within 6 hours. Literally - The R9 3950X (consumer desktop AMD CPU, not Threadripper, the AMD HEDT CPU) outperforms it, on literally everything - at 75% of the cost of the aforementioned Intel CPU.

Server companies are retiring 3 & 4 Xeon based servers and replacing them with 1 Eypc (AMD server CPU series). Between the cost savings (AMD CPUs are 1/2 the price of Xeons) and performance it is a no-brainer. In less than 2 years AMD has gone from 0% of the server market to 5%, and they should have at least 20% by the end of next year. And you have to be in the server market to realize just how fast that is.
