This looks more and more likely by the day, i would add the posibility of a 6C/6T 3500 at $160
I think 4c/8t might be better overall. More economical, and similar MT.
the product just below 3500 is known: the 3400g, which is a nicely clocked 12nm APU (now known capable of 3.7-4.2GHz)
3500 series line I imagine is the most interesting; imho it may be heterogeneous, and include 12nm and 7nm products.
3500 series sku's is where I imagine the bottom priced bottom binned 7nm to arrive at eventually (~early November). This will be a dumping ground for bottom bin 7nm die salvage, coming in the form of 4c/8t. Still, these should clock better than medium bin 12nm.
upper 3500 series (12nm parts) would be higher core count and be much superior in MT (while loosing much less in ST), so these would occupy the higher numbers of the 3500 series:
Here is a hypothetical (rough guess) desktop portion of the product line:
3200g 3.6-3.9 4c/4t 8CU ryzen 3 [now known as 3.6-4.0GHz]
3300g 3.4-3.8 4c/8t 8CU ryzen 3
3400g 3.8-4.1 4c/8t 11CU ryzen 5 [now known as 3.7-4.2GHz]
3500 4.0-4.3 4c/8t 7nm ryzen 5
3500x 4.2-4.5 4c/8t 7nm ryzen 5
3565 3.5-4.0 6c/12t 0CU ryzen 5
3585 3.0-4.0 8c/16t 0CU ryzen 7
3600 4.0-4.5 6c/12t 7nm ryzen 7
3700 4.3-4.7 6c/12t 7nm ryzen 7
3800 4.1-4.7 8c/16t 7nm ryzen 7
3800x 4.4-4.8 8c/16t 7nm ryzen 7
3920x 4.2-4.8 12c/24t 7nm ryzen 9 (paper launch)
The hypothetical 3585 would be a much less aggressive binning than the high binned 2700 (3.2-4.1) and 2700x (3.7-4.3); this would allow PR to achieve much greater 8c yields. I imagine 65W with ctdp up 95W and XFR enabled.
The 3500 line would also occupy the upper end of the high volume $150-$200 price range.
I imagine the 3400g would be priced slighty above $150, close to the 3500x, while the 3500 would be priced at or slightly below $150.
3200g would be at ~$115.
