    Over at the chiphell forums, a block diagram leaked of the AMD X570 Chipset. The diagram is not an official AMD one, however does seem to originate from a motherboard partner, and that does show it a...

    MSI has released a new bios (beta) for Zen2 support on my x370 motherboard. Haven't installed it yet.

    The diagram says "M.2 32Gbps" - that's actually ~4 GByte/s, the rate of PCI 3.0 x4 or PCIe 4.0 x2.
    M.2 slots with 4-lane PCIe 4.0 would have ~8 Gbyte/s (~64 Gbit/s).


    PS. It looks like at least on-die M.2 interface does have a full PCIe 4.0 x4 connection!

    X570 PCH shares its PCIe 4.0 x4 bandwidth between M.2, USB3, SATA, PCIe slots and onboard controllers - so its M.2 slot could be limited to x2 mode.

    Good thing all PCIe lanes now use the same PCie 4.0 protocol, and not the lower PCIe 3.0/2.0 data rate like it was on X470.

    Yeah, don't. I updated my Asrock board to the newest CPU support and now I am randomly crashing under load, and have seen a lot of reports of the same thing on other brands (after I pushed the button, of course - I should know better after all these years). And because of the nature of this update, you can't roll back.

    I would wait until you actually NEED support for the new CPUs before you update, there are likely more updates coming to fix this in the near future.

    So far, all 3 x570 motherboards I have seen have active cooling on the southbridge.

    Jeez no wonder it runs so hot...
    I'm pretty sure people would've been ok with some of the chipset lanes being 3.0.

    Yeah, the good old: Don't fix if not broken. I never felt the need to jump on every bios update, although these days running Intel might make the decisions even more difficult.

    Have we even saturated pcie 3.0 x8 fully yet this pcie hardly seems worth the added heat I think we would be ok waiting till this matures a little more.

    Yes, to my recollection, a Titan V can saturate 8 PCIe 3.0 lanes. It doesn't demand much more (I'm sure 12 lanes would be all it needs) and it's worth pointing out that x1 and x4 (M.2) slots can also be saturated, or, are insufficient for potential devices.

    I don't think it's so much a matter of having it mature more, but rather AMD should just simply provide fewer 4.0 lanes.

    The big gain will actually be the link between the CPU and the south bridge - it's a bottleneck that gets hit a lot under current designs, between gigabit network controllers, bridge-mounted m.2 slots, USB devices and SATA storage.The simple fact that you can now throw in multiple x4 m.2 drives that run at full speed is a huge leap for the desktop platform - you needed HEDT to do that before on both Intel and AMD. It's no wonder they killed Threadripper, there's really not a lot this can't do that it could for desktop systems. Heck, if this platform supports double DIMM density (and there's no reason why it shouldn't), there's pretty much no reason anyone would want TR.

    So, my question is this..... Would an X570 based motherboard benefit a first-gen Ryzen processor?

    @sykozis I'll make an educated guess here and say no.

    Whatever the CPU could do was done with the previous chipset.

    You will get new chipset features, but that's it.

    most bios update related crashes simply need a clear of the nvram and reconfiguration.

    Yeah, no. That was the first thing I did, I have been building PCs for decades so this isn't my first rodeo. I messed around a bit and it's a voltage issue. Changing from the stable voltage setting to the OC one that hands out higher values returned stablity. They apparently made some changes in that regard that aren't working out.

    So its beginning to look like that fan on the x570 chipset will be going all the time.
    (Yes, its from adoredtv, but we all knew it was hot.)

    Also looks like it would be one of those chipsets where you would replace the stock cooling probably immediately, to get the best out of it.
    You also wouldnt want any of that air going over M2 slots, it could be very warm already with the stock heatsinks.

    i'll be watercooling the cpu anyway, so just have to add a chipset cooler in the loop.

    how much the Killer E2500 outperforms the Intel I211-AT?

    Gigabit is gigabit, the tech is almost 20 years old at this point. The Intel controllers offload everything to the CPU via the drivers now, so there likely isn't going to be any performance difference between the two.

    who told you this lie, the I211-AT has hardware acceleration for dma coalescing and packet stamping.

    The point is not the bandwidth, both are 1Gb class controllers. The point is the latency and the CPU overhead. When I switched from a realtek Gb to the intel I211-AT was like jumping from a donkey wagon to a sport cart... The intel I211-AT is sold since Q4 2012, while the Killer E2500 should be a 2016 controller... As for bandwidth efficiency it should be more or less the same, I am just wondering about latency and driver overhead improvements and also packets scheduling..
    This is what I am talking about. the I211-AT is a decent controller compared to the older gigabit controllers and has a good set of driver settings, but now the reference controller is the Killer E2500....
