All things considered, AMD has already announced that Zen 4 CPUs, either Ryzen or EPYC, will only feature support for DDR5 memory so this means that there’s no DDR4 IMC on the Zen 4 core. If the red team was to bring Zen 4 on the existing AM4 motherboards, then it would have to make special variants of the chip that house the necessary DDR4 IMC as AM4 is an all-DDR4 platform.

The new Zen 4 Ryzen processors will have eight general purpose lanes, of which at least four will be required to be dedicated to an M.2 storage slot (always Gen 5). The other four lanes are up to the motherboard manufacturers. Some boards will use these to implement Thunderbolt 4 (Intel Maple Ridge JHL8540) or USB4 (ASMedia ASM4242). If none of these options are used, these lanes can go towards an additional M.2 slot.
With integrated graphics becoming standard on Zen 4, the first generation of AM5 processors will offer four dedicated display outputs, with HDMI 2.1 and DisplayPort 2.0 being supported, but neither being required as far as we understand. There are also four USB 3.2 Gen 2 (10 Gbps) ports and at least one USB 2.0 port coming from the processor. Three of the USB 3.2 ports also support DP Alt Mode, something we’ve seen several announced boards supporting on at least one USB-C port. This seems to be up to the motherboard manufacturers to implement once again.

AMD’s AM4 platform has profited both AMD and the company’s client base over the last five years. Yesterday evening, or this morning or afternoon, depending on your timezone, the company revealed the new AM5 platform and the company’s roadmap for the following number of years. However, what will happen to the popular AMD AM4 technology, such as the currently released Ryzen 7 5800X3D processor? Will the company offer further support? Dr. Lisa Su, CEO of AMD, has given hope to those satisfied with their AM4 processors and may have given a glimmer of hope for new designs to continue manufacturing.

The 12700K goes toe-to-toe with the 6-core, 12-thread Ryzen 5 5600X that has long been the favorite for enthusiasts because of its incredible blend of pricing and performance. These chips come with 65W and 105W TDP ratings, respectively, 32MB of L3 cache, and have only high-performance cores. Both chips support DDR4-3200 memory and the PCIe 4.0 interface.

The eight-core 16-thread Ryzen 7 5700G marks the arrival of AMD’s first 7nm ‘Cezanne’ Zen 3 APUs for desktop PCs, and today we’re taking an early look at the chips. AMD plans to use the Cezanne chips to plug big price gaps in its Ryzen 5000 lineup that dominates our Best CPU list and CPU Benchmark hierarchy, but they’re limited to the OEM market until the full retail launch on August 5, 2021. Anticipation is high, though, so we grabbed an off-the-shelf system from HP to take the Ryzen 7 5700G for a spin.

Without a doubt, the biggest shock is that the AM5 platform, at least initially on the 600 series motherboards, will not offer PCI-E 5.0 support. It appears that, at least for the moment, this will remain entirely exclusive to the Zen4 Genoa platform utilized for their HEDT EPYC processors. – The plot, however, does thicken.
It is being suggested that the AM5 socket will not be introduced until 2022 (and possibly quite late in the year). This means several things. Firstly, that it’s unlikely we’re going to get Ryzen 6000 CPU releases this year. Secondly, that Intel is going to have a pretty good head start in DDR5 memory. Thirdly though, and this is a big one, the gap is going to potentially be even bigger with Intel offering PCI-E 5.0 support while AMD, even with the launch of this new AM5 platform, will apparently not.

Per a prost from AMD via Reddit, we can expect an AGESA update shortly to address the known USB connectivity issues. AGESA 1.2.0.2 will be used to deploy this update to the masses:
We would like to thank the community here on r/AMD for its assistance with logs and reports as we investigated the intermittent USB connectivity you highlighted. With your help, we believe we have isolated the root cause and developed a solution that addresses a range of reported symptoms, including (but not limited to): USB port dropout, USB 2.0 audio crackling (e.g. DAC/AMP combos), and USB/PCIe Gen 4 exclusion.
AMD has prepared AGESA 1.2.0.2 to deploy this update, and we plan to distribute 1.2.0.2 to our motherboard partners for integration in about a week. Customers can expect downloadable BIOSes containing AGESA 1.2.0.2 to begin with beta updates in early April. The exact update schedule for your system will depend on the test and implementation schedule for your vendor and specific motherboard model. If you continue to experience intermittent USB connectivity issues after updating your system to AGESA 1.2.0.2, we encourage you to download the standalone AMD Bug Report Tool and open a ticket with AMD Customer Support.

While still yet to be officially announced, a claimed Ryzen 5 5300G has been put through some testing. User Hugo has a video detailing performance as well as specifications of a purported engineering sample. Numerous benchmarks against the 4350G, as well as other competing products are provided. Head on over and take a look.
Per a user post on Reddit, AMD has been giving out some advice on how to tackle the current USB issues with Ryzen 3/5000 series chips on the 4/500 motherboards. Somewhat unsurprisingly, the advice mimics much of what individual uses have reported doing to address the issue via C-States in the BIOS, as well as manual configuration of PCIE 3. Here’s AMD’s advice:
Based on user feedback we have received; the suggestions below could improve or resolve general USB device stuttering issues.
If you continue to experience USB connectivity problems after following the suggestions above, you may consider using either of the following workaround:
These settings are found in the BIOS. Please refer to the motherboard user manual if more information is needed.
