Well Intel donated Thunderbolt 3 to the USB-IF for USB 4, so if a USB 4 silicon manufacturer implements all the optional features of USB 4 such as PCIe tunneling, DisplayPort tunneling, Ethernet tunneling, DMA memory protection, USB-pd, and 40 Gbps support, then that USB 4 solution will function like a Thunderbolt 3 or 4 port. So I wouldn’t be surprised for some of the higher end x670e/x670 motherboards implement either Thunderbolt or usb4. I have been using 40 Gbps usb4 cables from cable matters that cost 1/3 the cost of equivalent thunderbolt4 cables and they function just the same. Displayport, 32 Gbps of PCIe, Ethernet, and up to 100W of power delivery.@dehjomz,
I moved your post to this AMD Ryzen thread because I was just thinking of posting something very similar here. Because my Ryzen-based B550 Vision D does not have a front-panel USB-C header, I am quite tempted by the new X670E series. Many (all?) of them will feature USB4, but it remains to be seen (a) whether amd-osx gurus will develop the requisite kernel patches and (b) to what extent USB4 is compatible with macOS.
USB4 implies support for Thunderbolt 3 unless the specifications explicitly say USB4 with Thunderbolt 4. So I'm eager to see if any of these boards will support Thunderbolt 4...
I’m excited for zen 4, the x670e motherboards seem to be a cut above z690 in terms of pcie5.0 and should have longevity. AMD has stated zen 4 will support up to 28 PCIe 5.0 lanes from the CPU itself. That’s insane. Now some board partners may not utilize all the available bandwidth and may wire their boards with PCIe 4.0 on the PCIe slots. But AMD stated that all their new boards must support at least one PCIe 5.0 NVMe slot. PCIe 5.0 storage is coming this year with speeds exceeding 12,000 MB/sec which is insane. So x670 should last a long time. Most z690 boards on the other hand don’t have pcie5.0 NVMe slots although some manufacturers did implement a PCIe 5.0 NVMe slot or offer an add-in M.2 card with PCIe 5.0 capability.
With the power efficiency of zen4 I may look to it for a mini itx build. But I’m waiting to see how zen 4 stacks up against meteor lake to see which one I’ll choose for my itx build. I just want a cool and quiet small form factor build that packs a punch.
