I also think that it's unlikely to see Ryzen use more than 8C (1 chiplet) as there's little reason for AMD to do so at this time. If they're getting ~10-15% bumps for both clock speed and IPC, there's sufficient reason to upgrade right there. For a big part of the market, 8C is already more than they need, so AMD is better off selling a 4C part as R3 that's much cheaper to produce and allows them to offer better prices to consumers.
Also, having to use 2 chiplets for Ryzen means that they can only effectively sell half the chips. Even though it might only cost an extra $20 in parts, that's potentially hundreds of dollars of revenue that they don't get by having more product. And they're already going to have limited supply due to being on a new process and wanting to use most of their chiplets for Epyc to get the most revenue. Even if they are just under parity with Intel, they'll still sell a lot of chips. If they're within 5% of Intel's 9900k, but sell that for what the top 8C/16T Ryzen goes for (~$350), it's pretty much a slam dunk in terms of which to buy.
Exactly. More than 8-core makes little sense on AM4. A 16-core would eat into threadripper and would make the IO die more complex and bigger.
They will save that step for next platform (AM5?) with Zen3 and probably ddr5 and pcie5.
More succinctly: An 8C minimum for R3, would probably have 99% of buyers choose the minimum. That drives down ASP/profits.
Exactly. The only way to make this work would be to lock the R3 give it low clocks. and that would just be stupid compared to simply making it a unlocked quad with high clocks. They can just dump all the poor dies with bad power characteristics into R3.
What is much more interesting for Ryzen3000 series and it's IO die. Will it support PCIe 4.0 and is the chipset connected to it via pcie 4.0?
