Fourteen-th generation components available in two x16 Gen 5 bays
The introduction of the 14th generation CPUs might enable motherboard makers to provide 2 slots for Gen 5 support at x16 using a straightforward BIOS update. With this change, the upcoming chips will offer an additional four lanes.
That would require a full overhaul of the motherboards. No source mentioned; I’m not familiar with that change. It seems unlikely for LGA 1700, and more lanes probably won’t appear until LGA 18xx for the 15th generation.
The distinction lies in how effectively a slightly modified motherboard performs compared to a fully redesigned one. This often comes from adding additional CPU pins to provide features like PCIe lanes. Sometimes older upgrades repurpose unused pins, though this is typically possible only on updated boards with newer chipsets. More lanes usually require a completely new socket because existing pins may not be available in the correct locations for traces. Currently, the main challenge is that PCIe 5 demands a more intricate motherboard layout with improved isolation—such as additional ground planes—to manage higher speeds. The complexity continues to rise as technology advances.
These are the leftover pins designed to match current bandwidth needs. I’m not sure if the details were outdated, but they appeared in a recent piece—we’ll check once Intel officially releases them.
It's something you could possibly achieve in theory, but only if practical considerations are met regarding unused pins for PCIe lanes. Routing these without a full redesign from the CPU die would likely be impractical. Typically, with a refreshed CPU, such radical changes aren't pursued—they require a complete chip redesign instead of minor adjustments. This kind of approach is more common in AMD, where they often make significant generational updates within the same socket. Of course, adding extra pins still demands a new motherboard, though it would remain backward compatible with older CPUs and boards generally support newer ones, even if they can't access the new features enabled by those pins.
The design must include dual x16 lanes from the beginning. Some boards provide dual gen5 x8 electrical, which translates to x16 physical, but that's the maximum available on today's consumer Intel platforms.
