Free interactive tool that shows you how PCIe lanes work on motherboards

I wish all manufacturers clearly gave info like this up front. AM4 boards would be nice.

I found it useful and thought others might also like it.

I’ve been struggling to find an AM5 board that can run three MI50s at 4x. This is perfect thank you.

Him are you sure about some of the PCI slots? I think some marked as 4x get downgraded to 1x on these boards…

Further edit - this maybe accurate - how are you getting this / confirming it?

Nice! One suggestion - please add AM4 socket boards. With current memory prices, AM5 with DDR5 is becoming unattainable for some. DDR4 prices are rising as well. But not nearly as bad as DDR5.

Very nice! Just a note (as the site says on bottom left side), this can vary depending on the CPU you use, would be nice to be able to select all different variations of supported CPUs as a future feature.

That is so incredibly useful, hardware vendors do such a bad job of properly advertising how many GPUs will actually work and with what combination of m.2 slots in use.

Wow, this is great! I don't know how they generate this but it's really impressive. One of the things that I've been surprised with is some older dual socket workstations have tons of PCI-E lanes, but none are hooked to the second CPU it seems

Warning: addicting site :)

Legendary!
