As Computex 2022 is largely an online event, MSI announced its upcoming AMD X670 and X670E boards shortly after AMD's keynote earlier today. Although the official press release didn't go into too many details, VideoCardz got their hands on more detailed information from MSI, which also brings some additional clarity to the platform as a whole. The most interesting slide is the one that lists the AM5 CPU's as having 28 PCIe 5.0 lanes, rather than the 24 PCIe lanes AMD mentioned in its presentation. This makes sense based on the fact that some X670/E boards have multiple PCIe 5.0 M.2 slots for NVMe drives. MSI's X670E Godlike and X670E Ace even feature three PCIe 5.0 x16 slots, although it's likely that this is in a x8/x8/x4 configuration, as these boards only have a single PCIe 5.0 M.2 slot. The same slide also mentions that all Raphael based CPUs will have support for HDMI 2.1 as well as DisplayPort 2.0, which will also work over USB Type-C Alt Mode. Interestingly it seems like not all AM5 CPUs will support DisplayPort 2.0, based on a footnote from MSI.

Other interesting titbits include a minimum CMOS chip size of 32 MB, which hopefully means we won't be seeing a repeat of the issue that the AM4 platform had, where AMD ran out of space for the AGESA, which led to multiple UEFI versions depending on the CPU used with the board. As far as MSI specific features goes, at least the high-end models will be getting eight to 10 layer PCBs and MSI will offer up to 24+2 power phases with improved heatsinks. MSI is also promising 60 W USB PD support for the front USB-C header. Just like ASUS, MSI will also offer an add-in card for more M.2 NVMe drives and MSI calls it the Xpander-Z Gen5 Dual. A common feature among all four boards is that they'll feature AMD's RZ616 WiFi 6E module, which is technically a MediaTek solution.

Although AMD didn't provide too many details during its Computex 2022 keynote speech about the upcoming AM5 platform, the company did announce that there will be at least three chipsets for the platform and showed pictures of some upcoming motherboards. ASUS has kindly filled in some more details about its upcoming ROG Crosshair X670E Extreme, which will be one of its higher-end models. Sadly the pictures posted are kind of tiny and the company didn't provide a shot of the rear I/O. That said, ASUS did point out some of its new features that we can expect to find on the ROG Crosshair X670E Extreme.

For starters, the board will have a pair of PCIe 5.0 x16 slots, although each slot is likely to only have eight lanes each, when both slots are in use, but ASUS doesn't mention any details here. The board has support for up to five M.2 NVMe SSDs, four of which support PCIe 5.0. Only two are onboard, with the other three being via ASUS' proprietary ROG PCIe 5.0 M.2 card and ROG GEN-Z.2 card. ASUS also promises USB4 support, as well as a USB 3.2 Gen 2x2 header with Quick Charge 4+ as well as up to 60 W charging support, for cases with a front USB-C port. On top of the rear I/O is an AniMe Matrix LED display that can be user customised.

It appears that ASRock got a little bit too excited and posted a Computex video earlier today that contained a brief glimpse of its upcoming X670E Taichi motherboard. The screenshot that was captured by Wccftech doesn't give away too much details, but the board appears to have at least three M.2 slots and a pair of PCIe x16 slots, of which at least one is meant to be of the PCIe 5.0 variety. The rest of the board is covered in heatsinks and various shrouds. The board will feature Realtek's ALC4082 USB attached audio codec, as well as a ESS ES9218 DAC. It is also said to sport a 26-phase VRM setup. The board is also expected to have Thunderbolt 4 support. The video has unfortunately been taken down, so we'll have to wait until next week to find out more details.

In related news, @momomo_us has leaked details of several upcoming AM5 motherboards, of which four models are from ASRock and two from ASUS. The ASRock models are the X670E Taichi mentioned above, the X670 PG Riptide, X670 Phantom Gaming 4 and the X670 Steel Legend. The two ASUS models are the ProArt X670E-Creator WiFi and the ProArt B650-Creator. Finally Gigabyte has revealed that the company will be displaying its X670 Aorus Xtreme, X670 Master, X670 Pro AX and X670 AERO D at Computex next week. The company mentions PCIe 5.0 for both graphics and the M.2 interface, which pretty much cements the earlier rumors about AMD offering PCIe 5.0 support for the M.2 interface on the AM5 platform.
