AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

Considering Ryzen 3900/3950 has two chiplets, I wonder how the Windows scheduler will handle that, or if there might be a Gaming Mode for the CPUs again.

2 chiplets was no issue with TR. The 4 chiplets were.
However lets not forget Ryzen has completely different design compared to previous generations. There is an IO chip that connects all the chiplets/CCX/Cores to all devices (like RAM).
It doesn't have to go through the IF accessing RAM and devices from different chiplet.

Very true. Hopefully we'll get some more Demos tomorrow, and reviews well before July 7th.

Just ordered my Free Noctua AM4 kit for my D15S as well. Hopefully that'll be sufficient for the 12 or possibly 16 core.

*If* they do 16 core Ryzen this generation, and it is a big if in my view, there is no way in hell it's only a $100 premium.

I would expect it to be minimum $200 premium, and wouldn't really expect it to be below $750.

Why? Why charge Threadripper money? This isn't a HEDT chip, so why charge HEDT prices? Plus, if 4 more cores than a 3900X commands $200 minimum premium, why does 4 more cores than a 3800X only command a $100 premium. Or to put it another way, if 8 to 12 cores costs $100 more, why should 12 to 16 core cost more than $100?

I think they'd be silly to launch it though. Higher binned dies (and they will be short of dies) should be going to EPYC and TR4. Margins are way higher, and additional market share gained on enthusiast will be minuscule, from having a 16 core (given they already have 12 and Intel only have 8).

But no, not really. EPYC gets the most power efficient chiplets by necessity of server requirements, so the best silicon will be diverted to servers of course. But Threadripper really doesn't need the "best" silicon any more, does it. Threadripper traditionally has the best or joint best clocks of the Ryzen family, yeah? Based on what's confirmed so far that'll be 4.6GHz, so we realistically can expect a 32c/64t 4.6GHz boost Threadripper.

Chiplets come off the wafer with only half the cores working, but those cores are still capable of 3.8/4.6GHz. That's arguably junk silicon. Yet, strap 8 of those together and suddenly you have a 32c/64t Threadripper that still matches the top Ryzens in clocks, as it's always done.

The notion that Threadripper needs the best silicon no longer applies to Zen 2.

Now, as to whether the 16 core Ryzen with a 4.7GHz boost will come out is still a valid argument, but it should be compared to the 3800X, not EPYC or Threadripper. Arguably the 2nd best 8 core chiplets will be going into the 3800X, yet 2 of those chiplets will be required for the 16 core - releasing the 16 core will actually eat into resources for the 3800X, which is likely to be the bigger seller of the 2 products.

I'm not 100% certain but wasnt the threadding issue in windows due to the scheduler not understanding that latency for inter thread traffic inside each CCX is much lower than inter CCX communication? Perhaps Ryzen 2 skirts the issue entirely by using the IO die to present as a single node, or perhaps the chiplet structure will exacerbate the problem. I'm excited to see actual reviews and testing on this.

i can see the 16c32t part being ~$750. ie $46/core - if 3800x is the "gamer's choice", hence the elevated asking price...then 16c will be the "halo" part with a higher asking price per core.
i guess i cannot be surprised if the 16c part would be $800 too...if AMD decides to price it the same as the 3800x part...

are the prices from AMD is just speculation?
