When you’re looking at motherboard features for your next PC build or upgrade, one of the most important specifications is how many PCIe lanes it supports, thanks to the combination of CPU and chipset. The better your motherboard, the more lanes you have for your graphics card, NVMe SSDs, and peripherals. But with modern consumer platforms from AMD and Intel, does stressing yourself out over how many PCIe lanes you have make sense? After all, both Ryzen 9000 and Arrow Lake have similar PCIe lane support. It’s not quite as clear-cut as not having to worry, but there are still some pitfalls when you choose your motherboard that you’ll need to be aware of.
