New information regarding AMD's next-generation AM5 platform which would support Zen 4 based Ryzen 5000 Desktop CPUs has leaked out over at GamersNexus. The site claims that AMD will offer two key technologies in its next-generation desktop lineup when it arrives in 2022 as showcased in an internal roadmap.

AMD Zen 4 Powered Ryzen 5000 Desktop CPUs To Feature DDR5 Memory and USB 4.0 Support in 2022's AM5 Platform

According to GamersNexus, the two key technologies that are quoted will include support for DDR5 memory and USB 4.0. The information is based on an internal roadmap and those are expected to change but there has been a lot of discussions in the rumor mill about AMD's AM5 platform that is expected to replace the AM4 platform (post Ryzen 4000 Desktop CPUs) will support the stated tech when it launches with AMD's next-generation CPUs.

Other details are mentioned which highlight that PCIe Gen 4.0 protocol will be retained on the new platform but the new socket will be the first to be introduced by AMD in several years after major success in the mainstream desktop segment with the AM4 platform. We already know that several memory manufacturers are ramping up DDR5 memory production later this year.

The roadmap we received, which we are unable to share as it is likely marked to find leakers, indicates that 2022 is the year that AMD is intending to get DDR5 into its premium desktop lineup. The 2022 platform will retain PCIe4 and will likely be a Zen4 product, also intended to feature native USB4 support. The APUs for that year also presently have DDR5 on the roadmap and are listed as Zen3+ parts. The mobile roadmap has DDR5 LP5 on-board for 2022 in the premium and gaming lines. via GamersNexus

SK Hynix has already confirmed mass production in late 2020. The DDR5 roadmap shows that the memory would scale up to 8400 MHz speeds and offer up to 64 GB capacities, twice as much as existing DDR4 modules. The DDR5 DRAM would also feature a lower operating voltage of 1.1V vs 1.2V on DDR4, resulting in better performance efficiency.

The other highlighted feature for AMD's next-gen platform, USB 4, is going to deliver increased transfer rates on par with Thunderbolt 3. With up to 40 Gbps bandwidth, the USB 4.0 protocol would enable much faster transfer speeds and will be compatible with all TB3 (Thunderbolt 3) devices released to date. The connector type of choice would be Type-C which will make easy plug & play with several devices.
