I7 14700K PCIe lane issues are clear and resolved quickly. Appreciate the help!
Intel claims the i7 14700K supports 20 PCIe lanes, while you're considering an ASUS TUF Z690 Plus with Wi-Fi d4. If you install a M.2 SSD in the top slot, will it reduce the 4070 Ti's PCIe lanes from 16 to 8? Also, should you use two M.2 slots or just one? More M.2 slots generally mean fewer PCIe lanes for the GPU.
20 lanes available, 16 dedicated to the highest PCI-E port, 4 lanes reserved for the top M.2 slot. Additional PCI-E connections on the board will divide the bandwidth of the primary slot as specified in your manual. The chipset offers 24 lanes from memory, with the remaining four allocated to the PCH or controller for USB devices and other peripherals.
It relies on the motherboard's configuration and the specific model you have. For context, even though a CPU could support only 20 PCIe lanes, these aren't limited to just one port. The CPU also connects via 8 DMI 4.0 links to the chipset, while the chipset can offer 28 PCIe lanes overall, distributing that bandwidth across multiple connections. For an M.2 slot to limit GPU performance, the board must route shared bandwidth between the PCIe slot and the M.2 port—typically seen in PCIe Gen 5 M.2 designs. The Z690 TUF avoids this by not sharing bandwidth with the main x16 slot, ensuring all ports remain available for the GPU without any loss of connectivity.
