Intel’s upcoming 600 series chipset, built for 12th Gen Core “Alder Lake-S” processors, won’t support PCIe 5.0. This is according to a PCI-SIG certification spotted by leaker KOMACHI_ENSAKA, which revealed that the chipset is limited to PCIe 4.0 speeds at 16 GT/s. The implication is that Alder Lake’s PCIe 5.0 support will be limited to their processors’ CPU lanes.

[…] with Intel supporting Gen 5.0 only on the CPU, motherboard prices may not be as expensive as they could be. It’s much easier for motherboard manufacturers to build boards around one or two Gen 5.0 PCI-e slots than to build the entire board to support Gen 5.0.

  1. Why is this an issue again. Pcie 4 and 5 were final very close to each other afaik 5 being more for servers than anything else.?

  2. “Yeah, PCI 5, we got that.”

    It’s just a marketing thing. They are pushing it CPU side so they can say they have it. Even if it doesn’t do any good. To be honest, AMD did the same thing with PCI 4, although they at least had a working end to end implementation, even if it didn’t really do any good apart from getting some pretty high benchmark storage scores.

    Not surprised.

  3. PCI-Express marches on, people already talking about version 5, but alas poor SATA has gone nowhere.

    Sure it has. It’s went to the recycle bin, and largely been replaced with NVMe. Well, I shouldn’t say that… SATA still has a place – spinners still use it, but spinners have pretty much plateaued with regard to speed and SATA is adequate for that already. But I’d say we won’t see any more evolution with SATA because it’s pretty much been replaced by NVMe as an interface, much in the same way spinners are being replaced with SSDs.
