1) Very interesting that they are still on the optimized 7nm process they used for the 3xxxXT chips. Seems they're saving a much bigger change for Zen4.
2) There will almost certainly be 5700X and 5600 type chips in the coming few months. I also would love to see them run up some 5850X and 5650X chips that focus on all-core and single-core boost, in addition to the cheaper and more poorly binned 5700X/5600 type chips.
3) For me, I'm going to stick with my 3600 until we get some more fill-in in the line-up and until prices drop and more details are known about the silicon and potential Zen4 plans. That may mean I don't give myself a nice Christmas present. But we'll see how the benchmarks play out for the things I do.
