Windows 10: RX 9070 XT on PCI-e 3, With R7 5800X

EvillS · Jul 18, 2025 at 12:27 AM

Any thoughts on how well an RX 9070 XT might work on an X470 motherboard with PCI-e 3 and the CPU above? Will the interface hold it back a lot or, will PCI-e 3 still provide enough bandwidth for it to work reasonably well? At some point in the next year or two, I do intend to move up to AM5 but, can get a reasonable B550 motherboard with PCI-e 4. I don't want to wait that long for a new GPU, because of new developments in The Elder Scrolls series.

Drivers OK for Gigabyte Radeon RX 5600 XT GAMING OC-6G???

I just looked at the selection on Newegg, and those 1600 series cards start at half the price for an AMD 5600-XT. I'm not a gamer, so raytracing isn't an issue for me. Now I need to look at the specs a little more carefully.

I didn't know that. Thanks. I'm going to guess that in the future, not sure exactly when, PCI-E 3 will be a limiting factor for video cards.

Wow. Same config as my new build. Look at post #1.

Now I have something I think I can work with. Thanks.

I wonder whether the 5600XT exploits PCI-E 4.0 or not? I did a little more reading, and one author suggested that it could use 8 PCI-E 4.0 lanes to achieve the same bandwidth as 16 PCI-E 3.0 lanes. No idea whether it's smart enough to do that. (Or whether it actually needs that much bandwidth.) The X570/3900X combination doesn't support a large number of PCI-E lanes. You may not wish to buy a 3rd generation Threadripper setup (a mere $1.5 k for the 24 core 3960x, plus $400 and up for a compatible MB, according to Newegg.)

My motherboard is an Asus X570 Plus Tuf Gaming, which is less expensive than the RoG Strix. I'm not much into overclocking. So far, it has been solid.
