These GPUs work identically whether you use a B550/X570 or a B450 motherboard.

I'm assisting a friend in planning his future PC setup. When stock levels settle, I'm unsure if PCIe 4.0 support is crucial for the new GPUs—especially since he's not using Gen 4 SSDs. Have any reviewers compared benchmarks for the same CPU on a B450 TOMAHAWK MAX versus a B550 TOMAHAWK? Thanks in advance!
The RX 6000 line gains advantages when paired with a B550 or B570 motherboard and a Ryzen 5000 CPU. Apart from this setup, there’s generally no significant variation.
The additional bandwidth could be useful as memory sharing and direct storage access become more common. Right now, likely few games will gain much from it. Using it with a new AMD chip offers some small performance gains, especially in certain titles—so yes, it helps if you have the latest processor. However, Nvidia is planning support for both Intel and AMD platforms, which means Gen 4 might not be essential, but staying on a current system could still matter depending on implementation details.
SAM is included in the upcoming DirectX 12, AMD released it first. Nvidia will offer a comparable product using DX as its foundation.
Yup, Nvidia will also have it (it's included in the dx12 so nothing really unique). It isn't limited to PCIe 4.0 as Nvidia mentioned all current systems should work with it. For gaming at 5600x, a better setup would be needed.
The comparison between PCIe 4.0 and 3.0 for GPU performance shows only a minor percentage change, typically under one percent. This difference is negligible and unlikely to significantly affect your experience. Unless you're pushing for top-tier benchmarks, sticking with PCIe 3.0 should be fine.
