I've heard Linus discuss motherboards and the psi-e Gen 4 slot reducing available lanes. If I had an M.2 drive and an RTX 3000 card, would one slow down the other due to lane limits? Or would both have sufficient bandwidth regardless of choices? Considering a 3060 with no shortages and a solid M.2 drive, would it matter if I go for a Ryzen 5 5600G CPU? Its integrated graphics are better than my current GTX 550 Ti until prices stabilize.

In the 3000 and 5000 series CPUs, you'll find a 16x4.0 configuration in the first slot and a 4x4.0 setup for the first M.2 drive port, all because they're connected straight to the processor.

The brief response is no due to prior information but also since current graphics cards and M.2 drives don’t fully leverage PCI4 bandwidth no matter how many lanes exist. In real life, most users probably won’t notice this because they rarely use drives in a way that maximizes the full capacity.

Ryzen provides 20 lanes connecting the CPU to both the primary x16 port and M.2 slot, ensuring maximum data transfer to these devices. Keep in mind that the APUs with names ending in 'G' lack PCIe Gen 4 support, relying instead on Gen 3. While this isn't a big issue for graphics cards now, it could affect Gen 4 NVMe drives. In regular use, you'd likely see no difference between Gen 3 and Gen 4, and Gen 3 drives are generally more affordable.
