Hello, is it possible (and is there any such product already on the market) to use 16 pcie gen 4.0 lanes to provide full bandwidth 2 x 16 pcie gen 3.0 lanes (with some latency drawbacks obviously)? Can we expect a dual socket epyc rome server that is capable to serve 8 full-bandwidth pcie 3.0 gpus? Isn't g292-z40 the one (the plx model is not provided by the manual)?
