Should I get an X470 board for VFIO?

#1

I want to play with VFIO in Linux to do GPU pass-through but my B450 only has a PCIE 3.0 16x slot and a 4x slot. Was thinking about getting an X470 board so I can have two 8x slots when my two cards are installed.

Might as well wait for X570

But why? I don’t see any added benefit. I just need the extra 8x slot. I don’t plan on going to Ryzen 3000 and the X470 boards are cheap.

Not trolling, unless you like buying mobos all the time spend the few extra $$$ get pcie 4.0 support and a good VRM the savings on X470 will be like $20

4000 at a min will be supported by AM4 and by the time you need to upgrade 4000 will be a nice upgrade

My Radeon VII is PCI 3.0 and I don’t plan on upgrading for a few years (about 3-4 years usually), so I still don’t see the benefit of waiting. Since X470 boards are around $120-150 depending on the features you want. It’s not like I am getting the ASUS Crosshair overkill $250 board. Also, I am note overclocking.

Would bet you are literally saving $20 to limit your options later. Storage will go to 4.0 and you will want that bandwidth then if you really want to save the $10-20 then go 400 series

Dude, we haven’t even gotten to Zen 2 (Ryzen 3000) yet. I am not waiting till 2021 for Ryzen 4000.
