I'm unsure if m.2 slots consume the CPU lanes. Two points: I need an Intel Arc GPU (x16) paired with an Intel Optane device (x4), and I'm looking for a Thunderbolt expansion card. The goal is to create a fully Intel-built system with LGA 1700 and Optane support. What should I do?

the processor features exactly that number of tracks, yet typically the motherboard includes an additional four or eight for 'slower' components such as SSDs.

On contemporary systems they typically offer four pathways to the CPU (PCIe 4.0 on newer models, often three on older ones), while adding 16 to 20 lanes or more, though performance is still limited by those initial four connections.

Most motherboard designs keep most of the main data paths hidden inside the chipset, reserving space for specific components like SATA controllers, audio ICs, and networking gear. Still, several PCIe ports and/or M.2 slots are exposed from the chipset.

It hinges on the specific Optane drives and what you're looking for. Cheap 32GB units or anything similar might not be ideal, but a more affordable Optan 905P or P5800X could work well if you require high IOPS with minimal delay. Overall, that's what I think.

It originates from the chipset. It actually has its own tracks.

He points out the limitation of available CPU lanes. In many consumer CPUs, there are over 20, with an additional 4 dedicated to the top NVME M.2 slot. The PCI-E lanes originate from the CPU itself, meaning data must be packed into a narrow bus. Usually only around four lanes connect the CPU to the chipset.
