Neowin has seen a slide showing a Raptor Lake-S platform overview and its upcoming features. This shows that next-gen Intel architecture will also be supporting DDR4 memory, just like 12th Gen Alder Lake-S did.
As you can see below, the slide lists DDR5-5600 as well as DDR4-3200 official memory support, though most kits on decent boards are typically able to run at much faster speeds.
This could give Intel a significant advantage over Ryzen 7000 and AM5 because AMD is going to be completely dependent on people wanting to move to more expensive DDR5 memory which is yet to offer tangible performance benefits.
The platform overview slide also confirms "Enhanced Core & Memory overclocking" which is likely going to be via Intel's XTU software version 126.96.36.199 which adds OC support on Windows 11 22H2 systems.
The slide was a part of the Intel 1H 2022 NAS Workshop event at Shenzhen China discussing Intel's roadmap for NAS products. You can view the other leaked images on the Weibo user's page at the source link below.
All this means that the battle between AMD and Intel is not as cut and dried as it appears. If AMD can convince users to move to DDR5 and force the price down it should do well, but this is not that likely. It is more possible that AMD will be ahead of its time and be priced out of the market by Intel, which is a rather strange state of affairs.
