Let’s not change the subject. The original statement was that Ryzen has 32 available lanes from the CPU and that is false.

Man , each Zen die has 32 lanes , it is quoted million times and it has been presented on every AMD presentation, and second my statement was about the fact that SATA and USB ports is directly connected to CPU (part of it), and third what you think from where did AMD pull 64 lanes for Threadripper and 128 for Epyc? That lanes are already there on CPU , AMD doesn't have separate mask for TR and Epyc , they just bin best dies for them

Sorry my bad about sata ports i completely forgot that they can be configured for something else beside sata, simply i put them with usb because they come from cpu and i totally forgot that that lanes can be used for something else. And the second thing about motherboard that supports sata ports from CPU there is bunch of them really bunch , but of top of my head here is one as you requested : ASUS TUF B350M-PLUS GAMING link : https://www.asus.com/us/Motherboards/TUF-B350M-PLUS-GAMING/specifications/ Look under storage section

It's pretty much mute point, but i'm not seeing what you're saying there under the storage section i'm seeing things like: AMD Ryzen™ Processors : 1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x 4 mode)*3 AMD 7th Generation A-series/Athlon™ Processors : 1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x 4 mode)*4 or 1 x M.2 Socket 3 with M Key, type 2242/2260/2280/22110 storage devices support (SATA mode & PCIE mode) But those are specifically talking about SATA mode, for M.2. Not actual sata ports. Personally, i'm not sure i understand the purpose of SATA mode, because to my knowledge, instead of using 4x PCI-Express lanes for the NVME M.2 drive, it instead runs over SATA. Theoretically, from what i've read, this frees up the 4x PCI-Express lanes(or up to 4x?), however, in these configurations, the extra 4x PCI-Express lanes can't be used for anything else? So you're freeing up the lanes to do...what with them? I could be very wrong in that, maybe they get freed up to use in PCI-Express slots....but that's not how i read it? But i'm also reading that is potentially automatic, depending on your m.2 SSD, and that some are designed for SATA mode and some are designed for PCI-Express mode, which again makes it all mute point lol

Loophole35:

Again show me where you can use more than 16 lanes from the CPU on the motherboard outside of the M.2 slot. I don't care how many lanes TR or EPYC has. AM4 gives you access to only 16 lanes from CPU to use how you wish.

I gave you sata port and usb and provided link to mobo that utilize that feature set,what more do you want?

AMD Ryzen™/7th Generation A-series/Athlon™ Processors : 2 x SATA 6Gb/s port(s), gray, You asked for board that uses SATA ports coming from CPU because you were convinced that there are any , and i provided link to the board, now why and how Asus choose that path is up to Asus, but the fact stands there are sata ports from cpu,you can use second m.2 drive but if you are using that sata ports then you are limited to 2xPCIE lanes for m.2 . Granted if you are not using Samsung drives (fastest) you want be bottle necked by those 2xPCIE, lots of m.2(maybe even majority) want be able to utilize 4xPCIE.

Maybe there will be a miracle and we'll get PCIe 4.0 with the 9700k.
