Slot Width _best_: Pcie

As PCIe 6.0 arrives (64 GB/s per x16 slot), physical width becomes less about raw speed and more about —the ability to split a x16 slot into two x8 or four x4 slots.

If your CPU supports PCIe 5.0, you can safely run a GPU at x8 without performance loss, freeing up lanes for multiple SSDs. pcie slot width

The width of a PCIe slot is crucial for several reasons: As PCIe 6

Motherboard manufacturers often install full-length x16 slots that are wired for x4 or even x1. You’ll see this on budget boards: two long silver slots, but only the top one has 16 lanes. The second runs at x4. You’ll see this on budget boards: two long

Here is the most critical point to understand:

This creates a trade-off. An x8 slot on a PCIe 5.0 motherboard is just as fast as an x16 slot on a PCIe 4.0 motherboard.
