I guess you missed my comment where someone I know at one of the board makers confirmed that the PCIe 4.0 lanes are only from the CPU?
Not many companies left. I guess VIA/VLI could've done something, or maybe Cypress (they have some chipset-like stuff), but beyond that, I don't know anyone else that has the in-house tech and know-how any more. ALi and SiS are long gone from that kind of business and the other USB 3.x host controller makers don't have enough in-house know-how to make the rest. I also doubt Nvidia would step up to make chipsets for their main competitor.
You got any other suggestions?
I guess you haven't used a modern, fast NVMe drive then, but hey, you're on a forum, so maybe someone cares about your opinion...
I boot in less than half the time with an NVMe drive over a SATA drive, for starters. Large programs like Photoshop loads in less than half the time, etc.
Just because you're sour because you didn't get a B550 in a timely manner isn't our problem and no reason to diss other technology.
