Quote:Intel's next-gen Alder Lake-S desktop CPUs will require a new LGA 1700 socket according to a leak from the company's official development resource website which lists the various projects that the firm is working on. Good ol' leakster momomo_us was able to grab a snap of the information there about the future Alder Lake platform(s).

The leak confirms that Intel is testing, or close to testing, power delivery and voltage regulation (VR) of the new LGA 1700 socket using the Gen5 VR Test Tool kit.

Intel only recently debuted LGA 1200 socket and Z490 chipset motherboards with Comet Lake-S and so it'll likely be a while before we see Alder Lake-S and socket LGA 1700 in action.

Rocket Lake-S, the immediate successor to Comet Lake-S, could be the first Intel platform to debut PCIe 4.0 support according to a leaked features slide (via Videocardz). Hence, the recent inclusion of PCIe 4.0 support on Gigabyte Z490 motherboards makes sense as it could be in anticipation of Rocket Lake-S and sort of confirms the existence of PCIe 4.0 compatibility on the next-gen Intel desktop lineup. So, Alder Lake-S might be when PCIe 4.0 support matures and expands to more affordable motherboard options.
