Processors

I read online and discover that AMD announcement for awhile back about X570 with AM4 Ryzen 5000 processor.  The AM4 processor can produce 4 10Gbps USB ports (USB 3.2 Gen 2?).

See image. 

I recently discover that the processor only has USB 3.2 Gen 1 bus instead of USB 3.2 Gen 2 bus (that was advertised). 

I was wondering what is the  correct version of the USB 3.2 bus? Is it USB 3.2 Gen 1 or USB 3.2 Gen 2?  for the Ryzen processor's USB bus? 

Thanks

The motherboards is output USB 3.2 Gen 1, but the CPU can provide USB Gen 2, right?
