PCI Express® Version PCIe® 3.0/4.0 applies to M.2 NVMe SSD?

AMD Ryzen™ 5 5600G only has PCI Express® Version PCIe® 3.0 https://www.amd.com/en/products/apu/amd-ryzen-5-5600g, does that mean even with a motherboard which has M.2 PCIe 4.0/3.0 x4, it wouldn't be able to take advantage of ssd like Samsung 980 PRO PCIe 4.0 NVMe? or the PCI Express® Version PCIe® 3.0/4.0 from 5600G only applies to video card slots?

I'm getting confused, I always thought getting a fast M.2 NVMe SSD like Samsung 980 PRO overwrites PCIe® 3.0/4.0, no?

I'm specifically only looking at Windows boot times, do I need to be concerned (future proof) about the 5600G's PCI Express® Version PCIe® 3.0 if I'm to build a non-gaming PC now?

Thanks.

You'd need an X570 board to take advantage of a PCIe Gen 4 drive in this case, and it would likely be the bottom slot (handled by the chipset).

That being said, if Windows boot times are all you're worried about, stick with a cheaper Gen 3 drive and a board based on the B550 chipset. You won't see any real difference between Gen 3 & Gen 4 in that case.

To clarify your point about a drive "overriding" what the CPU or Motherboard can do, that's not how it works. You can have a Ferrari, but it isn't going to get you to your destination quicker during rush hour in Toronto.

Got it, thanks.

Yes, only Windows boot times.

This is the board I'm getting.

Yup, you'll be limited to PCIe Gen 3 speeds.

From the manual :
AMD B550 Chipset
∙ 6x SATA 6Gb/s ports
∙ 2x M.2 slots (Key M)
▪ M2_1 slot (from AMD Processor)
▫ Supports PCIe 4.0/ 3.0 x4*
▫ Supports SATA 6Gb/s
▫ Supports 2242/ 2260/ 2280/ 22110 storage devices
▪ M2_2 slot (from AMD B550 chipset)
▫ Supports PCIe 3.0x4
▫ Supports 2242/ 2260/ 2280 storage devices
* The supported specification depends on installed processor.

It's fine. You won't notice the difference between Gen3 and Gen4.
