If your going by the zen 3 slides vs stock Intel CPU I still think Intel will win when overclocked and is now the cheaper option for 6 and 8 cores.Or you can pick up a B550 and a 3900x cheaper than that 10850K + z490, and have even more cores and an upgrade path to Zen 3 when the price is right for you.
It's kinda funny how this release has flipped the intel argument on its head - last week people were arguing that AMD would get you more cores at a given price-point, but intel might give you a few more FPS if that was important. This week we have the reverse. But the thing is, Zen2 still exists.
If you want more cores, go Zen 2. You'll get better value/more cores than the intel counterpart. If you need the last few FPS, go Zen 3 for top of the range gaming/IPC/single-thread performance.
Intel doesn't have a win on either front.
Remember those nvidia slides showing the 3080 at double the performance of the 2080 when in reality it's 50-80% depending on the resolution. Will wait and see the proper benchmarks before taking a company at its word.
