    Be nice if they do work in the normal AM4 boards, specifically the B450M's

    Don't think it'll hurt AMD much if Zen 3 is delayed further than September... the current Ryzen line-up is performing really well and selling better.

    Could be interesting if their mobile chips follow a yearly pattern of updates - e.g. Zen 3 5900H/5900HS launching roughly this time next year.

    looking forward to Zen3 options and a new GPU that actually performs inline with its pricing

    Thunderbolt versus USB 4.0 a new dawn of confusion for AMD as intel goes Thunderbolt 4

    Sadly for those invested in it, Thunderbolt will die at this rate. Proprietary always does.

    Sadly? From my horrible experience with Thunderbolt so called docking stations it can't be taken out back and shot in the face fast enough.

    If you are buying a new system then a newer chipset is worth a few quid more certainly. I don't see the point in replacing a board you already have though.

    There isn't much call for PCIe gen 4 yet. It seems the Gen 3 SSDs have higher random IOPS than the currently optimised for linear reading gen 4 models, leading AMD to recommend threadripper benchmarkers to avoid gen4 SSDs. If you are buying a low end graphics card that only has 8 PCIe lanes and only has 4GB of vram then you get a boost from gen 4, which shows there will be cases but it is a pretty narrow band right now.

    I am certainly not ditching my existing X470 board yet.

    I do wonder with all the delays if the B550 is just going to be labelled B650 now.

    B550 looks to be a decent upgrade in several areas from B450. More pci lanes etc. for starters.
    Gen4 is a slightly different beast yes but seeing as gen3 works in it anyway. I'm hearing from a few sources that AMD will be recommending B550 over B450 for 4000 series cpu anyhoo due to tweaks with precision boost and those extra pci lanes but dropping support (possibly) for 1000 and 2000 series cpu's

    Upgrading from a B450 - that's harder but I'm pretty sure you'd get more from a cpu and board combo than just a cpu to offset the cost a tad

    Re: Motherboard makers: AMD Ryzen 4000 desktop CPUs arrive in Sept

    Well I am not changing out a £150 B450 mini-ITX motherboard for a new CPU! If the Ryzen 4000 series does not work with my B450 motherboard,I will get a Ryzen 7 3700X and that will need to last me the next few years. Also AMD artifically stopped companies from making PCI-E 4.0 compatible BIOSes on B450 motherboards,and since my motherboard is a mini-ITX motherboard which will have more PCB layers and shorter signal paths,there is probably no real reason why it can't support it either!

    The B550 looks to be a variant of the same ASMedia chipset used in the B450 AFAIK.

    Also I am sure,the money saved from having to get a new motherboard is probably best put towards a new GPU at some point,especially with the ways things are going. Its really in the interest of AMD to try and at least make B450 motherboards work,as they didn't launch the B550 for Zen2,so for many people it will only one generation of upgrades as it was B450 or X570 for them,and the need for active chipset cooling put off a number of people from what I gather. Intel was mocked for this,and AMD will get the same negative PR.

    Not disagreeing - I guess it will be down to the motherboard maker to support 4000 series cpu's.
    However Intel have been doing this for years and getting away with it. My point is not that it won't work but that you will probably not have the best experience. 3 x B450's here with a mix of 2600's and a 2700X. I got them due to the deals I managed to snaffle up (2 x B450's were under £70 delivered) and the other was s/hand and under £30 but is ATX. Cpu's were £100, £110 and £135 all new

    Wont hold my breath .. will be nice to see what the official specs are, plus eco-offerings in the itx space (low draw, NUC-type 35w/45w or lower) . Is it crows that spread it?

    Technically they should, but that comes down to the design of the boards.
    Small BIOS chips limit the size of a BIOS, and therefore features and support.
    And power delivery was not built often for CPUs beyond the tier of the board, mid-range 6-core or even quad-core on the very cheapest.
    Some boards are simply more future proofed than others.

    Can't see power draw being an issue. Heck my 2700 is "only" 65 watts and that's 8c/16t
