I didn't express this clearly. Yes, they can run SATA via the MoBo chipset (e.g. B650/E), but eat up PCIe 4.0 capacity. I've read about users complaining their SATA SSD and SATA HDDs running slower on AM5 than AM4, but I don't have an AM5 so can't confirm. > > The iGPU on AM5 can drive one dedicated display, while 3 more displays can > > be hooked up to the USB-C ports as DP-alt mode. > > What do you mean with one dedicated display? I've read this to mean one HDMI 4K display coming off the graphics core. Lower resolutions using DPs (shared?). I haven't looked into this aspect in more detail for more than a year now. A couple of MoBos I looked at mentioned they only supported 3 displays at a time, so I took this to be an AM5 graphics limitation. Later on I read something from AMD speaking of 4 displays. I don't know more about it. > According to > https://www.anandtech.com/show/17585/amd-zen-4-ryzen-9-7950x-and-ryzen-5-76 > 00x-review-retaking-the-high-end/3 the AM4 iGPU supports three displays, > AM5’s four.

Although this video does offer a comparison, which I expect won't be relevant to the OP's use case: https://www.youtube.com/watch?v=WiEmCOQi5rg
