Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

Just from a sales perspective I think they will only do 12 and 16 core.

I think I am going to disagree here.

AMD specifically emphasized gaming performance. AMD is now fully on board in keeping that crown. The best gaming performance could be obtained from single chiplet 8 core CPU with high L3 cache.

2 reasons:
- higher power to cores in 8 core vs. 16 core config, can lead to higher sustained turbo clocks
- 1 chiplet eliminates coherency traffic and some memory latency hit

The fact that 5950 has a higher boost clock just means someone was not thinking things through fully.

The easiest way for AMD to keep gaming performance crown is to release highest clock 8 core CPU with 1-4 layers of V-Cache.

In the case of AMD stacking SRAM on top on L3 on CCD, the SRAM stacked and the L3 should have the same surface area, so it should be made both in same process. How the TSV points will match between bottom SRAM and L3 cache CCD if it's in different process ? Maybe TSMC will bring too N6 on N6...

I hope we can now agree that Zen3d on desktop missed the window where it would have been relevant, leadership product.

By missing the window, Zen3D, and has been relegated to irrelevance...

Throwing all the bad dies at the 5800x3d is the cherry on top.
