Hey, I see you're trying to optimize your build with the X670E Aorus Master, 9800X3D, and RTX4080. It's great that you're thinking about performance bottlenecks. Running four M.2 PCIe 4.0 NVMe SSDs—two on the CPU and two on the chipset—can be tricky. Make sure your system meets the bandwidth requirements for those drives; otherwise, you might hit limits elsewhere. Let me know if you need more tips!
The two CPU m.2 slots will always operate at maximum performance with your processor. The chipset sockets connect via a shared x4 link, and the SATA, USB, LAN, etc. connections, so they could face delays when used together or if many devices are connected to the chipset.
Welcome to the discussions! Of course, in theory there might be a delay on certain tasks. If your system has a solid CPU, slots A and B will operate at full PCIe Gen 4 x4 speed, while slots C and D share one PCIe Gen 4 x4 connection for the CPU, the 2.5Gb/s Ethernet link, the built-in Wi-Fi card, and nearly all USB ports except one. In practice, however, that connection can handle up to 8GB/s or 32Gbps in each direction—more than enough unless you're running demanding applications simultaneously. Since you identify as a gamer rather than a developer or lab setup person, you’re unlikely to hit this real-world limitation even if you push everything to its limit.
