yea fuck intel i225, couldn't get that shit working 2.5, just bought an addin card cuz my network is 2.5gbe and split to 1gbe (for ps5 and shit)
Exactly, and most people wouldn't even know about the problem without looking into it so deeply or consulting a spreadsheet, but given how no one is using it anymore on the x870 boards, you can figure that they all said "fuck that noise" and dumped Intel altogether.
I just wish more had split the lanes in a sensible way on the new boards because if you're buying into the platform now, it makes even more sense than with the x670(e) to think ahead about future GPUs and whether or not they'll be bottlenecked, and frankly for the price of GPUs in general, fuck sharing lane with storage that is only getting cheaper. And
double fuck sharing with storage that has negligible returns that aren't even being utilized by anything.
The rub is how it's some low end boards did just that, e.g. the x870 Tomahawk handles it by sharing M.2 bandwith with the USB 4.0, because that actually makes sense:
* USB 40Gbps Type-C ports on the back panel and M2_2 slot share PCIe 5.0 x4 bandwidth. Both run at PCIe 5.0 x2 when a device is installed in the M2_2 slot. You can switch M2_2 to PCIe 5.0 x4 in the BIOS, but this will disable the USB 40Gbps Type-C ports
*** PCI_E3 slot will run at x2 speed when installing device in the M2_3 slot. You can switch PCI_E3 slot to x4 in the BIOS, but this will disable the M2_3 slot.
Meanwhile, this is the x870e Carbon that also has the privilege of costing $200 more:
* PCI_E1 & PCI_E2 & M.2_2 share the bandwidth, and PCIe version support varies depending on the CPU. Please refer to the PCIe configuration table in the manual for more details.
I'd suck it up and get the Taichi Lite without hesitation if they just did what the less expensive Nova did and give you an extra fifth m.2 slots and 4 SATA instead of the two extra SATA, but the Tomahawk is looking
mighty tempting for being cheaper than all of them.
