"The 12 core doesn't need to use top tier chips to be made only 6 of the chips need to work and reach the desired clock speeds."
It also fits into 105W TDP with 105W (or a little more) motherboards and 105W standard cooler. Hypothetical 16C/32T 3990X needs something like 125W to make sense. And of course it would be memory-limited in a whole lot of workloads, just 128bits of DDR4 serving 32 threads is insane.
The server chips may go through a lot more validation, but they don’t need to bin that high in clock. The sever parts will mostly be in the 2.5 GHz range or lower. They will bin them heavily for power consumption more than anything else.
Sever chips don't launch till Q3, Ryzen launches a minimum of 2 months and up to 5 months before the Rome Launch. The only binning they'll be doing in the meantime is strictly for Ryzen.
As they did before, it's a fair bet that all the very best clocking chiplets are being stockpiled for the next Threadripper. Which Lisa Su confirmed (after the keynote) that they are still working on.
Obviously the faster 8 core chiplets have to be binned to introduce the Ryzen 9 3950X, or the Ryzen 10 perhaps. It will take time for good 8 core chiplets to get set aside for new SKU's in the near future, and this was most expected. No mention of Ryzen 3 either. Zen 2 is obviously a staggered release over the second half of 2019. So I expect a 12-core Ryzen 7 3850X at or near 5Ghz, and a 16 core Ryzen 9 3850X and then a Ryzen 3 6-core with SMT and a 6-core without SMT. I'm sure we will see 6, 8, 12 and 16 core Ryzens for the Zen 2 family stack. There is simply no freggin way AMD would just toss all those extra fast or partially defective chiplets in the trash which could be used instead for Ryzen 9 or Ryzen 3. I'm betting the 5Ghz parts come later this year too once enough passing chiplets have been binned just to answer Intel's upcoming 10-core desktop parts. Think about it, the Zen 2 16 core at 5Ghz boost would easily make Intel's 10-core chips look silly as well. They can't let all their eggs out of the basket just yet. Besides its clear that many of the X570 boards have VRM's designed for 16 core CPU's.
5GHz this year... not likely. In 2 to 3 years... maybe. This is good improvement! We can Expect some golden samples to reach 4.7GHz maybe. The power usage seems to ramp up very quicly from 4.4 to 4.5GHz! So getting 4.6 GHz seems to be hard at this moment. Requires a good sample.
We don't know how high these new processors will actually clock. Intel was hitting 5.0GHz for years before 5.0GHz became the official boost/turbo speed. Of course, Intel doesn't talk about the REAL TDP of chips, just the TDP at base speeds. So if AMD is hitting 4.6GHz on 12 cores official boost, it is possible these chips CAN run faster with better cooling and a motherboard that can handle the increased power demand. Asus ROG boards tend to be overkill for the official clock speeds, and can handle a LOT more power demand.

the tdps you are using boost clocks to compare have alot more to do with the base clocks. education sonTargon - Monday, May 27, 2019 - link
