Maybe it's hard to fathom an Intel chipset that actually supports more than a single generation of CPU designs; and if so, you're forgiven, because it seems the blue giant has mostly forgotten of thinking about platform longevity and upgradeability. However, we might be in for a rare treat, if the words from a Gigabyte representative are to be taken seriously. In a Q&A regarding Gigabyte's latest generation Z490 motherboards, a user questioned the Gigabyte representatives whether their Z490-based platforms would support upcoming Rocket Lake designs. The answer, which came with a caveat of "I don't know if this should be made public", was that yes: Z490 will support Rocket Lake-S.
If true, this may shed some light on why motherboard manufacturers have given so much importance to PCIe 4.0 marketing on their Z490 motherboards... Whose chipset doesn't support PCIe 4.0 from the get-go. However, with next-generation Rocket Lake-S expectedly sporting the same 14 nm fabrication process albeit with a new microarchitecture, a wider DMI 3.0 8x band, Intel's high-performance Xe graphics architecture design and PCIe 4.0 support on a platform level, it does begin to make sense that manufacturers would mention PCIe 4.0 support on the current Z490. Because if CPU compatibility is maintained, that means that users looking to drop-in a Rocket Lake-S CPU will at the very least be able to enjoy 20 lanes of PCIe 4.0 in these ready-made motherboards.
