Custom Nvidia network cards I guess.

Blackwell DC (B200/B300)

while the B200 chip itself could do PCIe6 as it was planned for GB200, there is no system around it with Gen6. the official DGX B200 is just PCIe5.

GB300 is indeed Gen6.

into a Gen6 Bianca board (baseboard for GB300). that's it today.

how you use those today is twofold:

- Gen5 x32 via two x16 slots (this is how most people use them)

- use actually the CX8 as your PCIe switch directly to your GPUs: https://www.servethehome.com/this-is-the-nvidia-mgx-pcie-swi...

Nvidia only for now. Precisely because they got fed up with Intel and AMD ( And Amphere as well ) for extremely slow PCIe adoption.

I believe only next Gen Intel and AMD Zen6 will get PCIe 6.0.

I am hoping Nvidia officially move into Server CPU market not only for their CPU but for wider Web Hosting as well. More competition for Server Hardware.
