Hi again! So…based on my previous post, it’d seem that it’s going to be quite some headache to get an old intel 6700 CPU with a PCIe 3.0 to work decently with more up to date GPUs (that is, to see a decent improvement in performance at all). I’d like to do a cross-jump to AMD CPUs this time, to be paired with a 6800XT or a 7800XT. I intend to game on Linux, although there will be a Win10 partition for the troublesome games, and also for the Vive Wireless, which is unsupported on Linux. But I’ve been out of the AMD loop for a while. What’s cooking? What would be a good second-to-last generation CPU recommendation or so? Am I missing any important tech if I don’t choose the latest and the greatest? Is ReBAR a thing yet? (Not sure if this is the answer to PS5’s direct asset streaming from the SSD straight to the GPU). At this point, I’d like to know what CPUs are adviseable, in order to get some idea for a PC build, so I can go get quotes…and see if that’s something I’d be able to afford :)

    The first generation of AM5 socket CPUs (7000 series) came out this year. AM5 boards are also the first generation DDR5 boards as well. If you’re looking to build something you can upgrade with some drop in replacement CPUs in another 2 or 3 years, then go with an AM5 motherboard. Otherwise go AM4 and put in a 5800x3d.

    I think the sensible long term decision right now is to go with AM5 if you’re doing a new build. If it’s primarily a gaming machine, you’ll want an x3d variant processor as those have triple the L3 cache which games tend to do much better with.

      So, regardless the mobo is AM4 or AM5, the CPU you’d advise would be the same? Are they compatible? Or what would be an advisable CPU on AM5? Thanks!

        Nope. AM4 sockets are AMD Ryzen 1000 series through 5000 series. Starting at Ryzen 7000 series CPUs, AMD switched to the AM5 socket and DDR5 RAM

        (In case you’re wondering where Ryzen 6000 went, it’s mobile/laptop only)

        Edit: for specific processor, that comes down to your needs in your build. If you’re primarily gaming and want to do a 7800xt GPU, you probably want a 7600 (possibly the 7600x of you want to pverclock). If you have deep pockets you can go for a 7800x3d or even a 7900x3d or 7950x3d. I personally don’t think those are necessary if you’re pairing it with a 7800xt though. A 7600 CPU should be more than capable to power that. And if you’re planning on upgrading in a year or two, the 7600 will save you money now which you can throw into a beefier CPU later on.
