    well no, because you don't if you already have an X570, which has been out for nearly a year, - will be more like 18mths by the time 4000 series actually arrives. So remaining on AM4 is advantageous for those people who want to pop in an upgrade.

    As the link says, they have delivered what they promised - it is 2020 now, it'll be the tail end of it.. People are just being bitchy , with the small exception that I mentioned , that being those buying B450 mobo's currently, due to 550's MIA (until now) . I do think they can do better here, or 'could have' if there's technical reasons behind not officially supporting 450

    Yeah pretty much. the bios excuse is week, there are even x570 boards have a 16mb bios just like B350/some B450. I can see how they can't do official support as adding zen3 to B450 etc as will likely mean removing zen/zen+ support that the motherboard box says it supports to free up space on 16mb bios boards, but if they don't do 'select beta' support like 95% of B350/x370 boards have for zen2 that's a shitty move.

    Also AMD you could have avoided all this by mandating 32mb bios chips, cost is next to nothing, but of course board makers will happily save 20c if they can get away with it.

    Also there is a slide that shows that b550 will only have support for pcie 4 traces natively

    gen 4 nvme. vs gen 3. differences are useless for gamers really (only interested in app load times). only large file transfer peeps need that.

    ssd versus nvme gen 3 load times diff is usually less than 2 seconds difference. and between gen 4 and gen 3 about or less than half a second. :lol:

    ...pcie 4 for graphics? not needed is it?

    Silver lining when 4000 series drops their will be a lot of 3000 series in the for sale, was looking forward to putting a 4000 series in my X470 but now just have to upgrade to a better Zen 2

    But don't X570 have limited backwards compatibility ? IE no Ryzen 1000 support at least officially . The space used for 1000 got kicked forward to 4000 for x570.

    Yep and they could do the exact thing for B450 boards with 16mb bios, new bios that ditches zen1 support in favour of zen3, exactly like my and stacks of other b350 boards already do for zen2 (new bioses ditches pre zen1 cpu support to make space). but if the AMD agesa code (supplied as binary only) explicitely blocks/won't work on B450 as hardwareunboxed have suggested is AMD's current plan, motherboard makers can't offer this as an option.

    There are certainly some speed gains on PCIE4 for NVME in benchmarks, but whether its useful or not totally depends on your use case really. If you tend to do a lot of large sequential transfers, then sure, its noticeably faster, but for any other use case although its faster the extra speed is unlikely to be noticeable for most.

    A 2080Ti almost saturates a PCIE3 x8 slot, so even if Ampere or RDNA2 use DOUBLE the bandwidth of any current GPU, they will still max out at under PCIE3 x16. PCIE4 won't make any useful difference to GPU performance for at least a couple more generations of GPU IMHO.

    I think you will find a 2080ti nearly saturates an x16 slot not x8.

    A 5500xt is problematic in a PCIe 3 board at x8.

    PCIe 4 is going to be a must have with the new videocards and their memory compression changing.
    Just look to the upcoming consoles, it gives a clue, using very fast memory and bespoke ssd solutions.

    Hardware unboxed I know made a video on the 5500xt.

    It really depends on what you are running. Some games will show no difference at all.
    It's when the card starts moving around memory that it will push the bus the hardest.

    makes me wonder what other gcards are limited to X8 ? :confused:

    PCIe 3.0 is plenty of bandwidth for now *

    * if you start smashing PCIe 3.0 limits you have already run out of memory on your graphics card. IE your frame rate already sucks. How much PCIe bandwidth you have underneath the hood determines how bad the suck is.

    Rumour/leak... take truck loads of salt...

    Apparently the leaker is legit and has a good track record, but don't they say that about every leaker? :D

    We know its at least 15% faster in ALU and 50% faster in FPU.
    Certainly conceivable its a good 20% in many games and more in professional software and encoding..

    Some more rumours... some details on a Zen 3 A0 stepping has appeared. 8 core with 4.6Ghz boost, 4Ghz base, 16 core with 4.6Ghz boost, and 3.7Ghz base.
    Source - https://www.igorslab.de/en/new-deta...us-have-appeared-the-image-is-getting-denser/

    In comparison, 3950X A0 was 4.2GHz boost and retail 4.7GHz. Some folk may feel that this is a cause for celebration as it clearly proves that Zen 3 parts will hit 5Ghz... :D

    Maybe it is finally time for amd to take the outright throne from intel, it has been a long long time coming. My fingers get excited at the thought of a new amd build. The last time I had my main rig built around amd was back in the PhenomII days. I did dabble with bulldozer once but I'm still trying to get that taste out of my mouth :p Even a mild clock boost addition with those ipc gains will be pretty exciting.

    yeah i have a feeling when next gen gpus drop pcie3 is gonna be a huge bottleneck at 1440-4k+ 0.1% fps already suffers
