No need for SATA ports. Will build x3950 or 4xxx.

Any options for mobos like that? Could use 2 M2s which is already not a problem.

Ryzen 3000 CPUs will have a total of 24 PCIe Gen4 lanes, yes, Gen 4.0.
Four out of the twenty-four are used for the interconnect to the X570 chipset, leaving 20 lanes Gen 4.0 for other utilization.

-16 for dedicated video card.

that leaves u with 4 left for the entire system.

4x pci-e lanes gives you 1 nVME drive after video card.
Or
You can run your Video card in 8X, and free up another 8x for another *Drum Roll Please* 3 x nVME support.
You see your at the mercy of how many PCI-E lanes your cpu has, so having a boat load of nVME ports do not add up on your platform.
Try ThreadRipper if you want a plethora of nVME, and you can use a nVME Bifurication card on top if you board just cant handle it physically.

Your asking and want do not add up or make sense.
You need the Sata ports, unless u intend to drop a 4TB+ nVME on that system.

pretty sure 5700XT is happy with PCIE4 X8.

My board has 3 NVMe gen 4, and 4 SATA. Also has the x16 slots.

Yeah my aorus ultra has similar setup but with 6 sata ports. The last nvme slot shares pcie with sata 4 and 5. Also all three PICe are x16.

The chipset provided lanes will be bandwidth limited by the PCIe x4 link, but since it's still almost 8GB/s both ways, it'll be a non-issue for a while yet. Unlike on Intel's mainstream platforms.

Some high-end AM4 boards do support bifurcation. It was even added in a BIOS update for my Crosshair VI, so everything is possible.

pretty sure 5700XT is happy with PCIE4 X8.
Can't say my 5600 is limited by even an x8 3.0 connection. Running a graphics card on a x8 has almost always been a non-issue, and if it frees up lanes for additional storage, I'm quite happy making the tradeoff.

Thanks for such an exhaustive explanation.

I will not use SATA. Period. I will go with 2 nvme SSDs.
