Asrock like to do that thing, where they design one PCB and make a couple models out of it - one with less features, one with more…
The same as B350 Pro4 and B350 Gaming K4…
I own the X399 Taichi and I had considered the F1tal1ty but I came to the conclusion that the only difference is the 10 GBps NIC. I am able to buy a 10 GBps add-on card separately and the overall price will still be lower than the Fatal1ty. I thing that these two Asrock motherboards are really good and I am very happy with my purchase.
The only issue I have is that the computer doesn’t come back from sleep. I am in contact with the Asrock support about that. I haven’t found the problem yet but I don’t think that the motherboard is the culprit. Contrary to what I read on other forums and reviews pages about Asrock, I would say that the service is ok.
I had the exact same thought, however, after mulling it over, I decided that I wanted the 10gb card integrated to free up future uses for all the PCIe slots. I saw it as a waste of the lanes to tie them up with a card that frankly doesn’t utilize the full bandwidth of the available slots. To each his own, but I’m also happy with the fatal1ty board. Good luck to the OP in your search.
THe biggest most significant difference is the 10Gb/e like mentioned above.
For the rest appart from the design, they are totally identical.
Same vrm design etc.
If you dont really need 10Gb/e, then paying extra for the Fatality isnt really worth it imo.
