To get 192-bit security with RSA you'd need 7680-bit RSA key and with ECC you need 384-bit key as mentioned in the article. That assumes classical attacks only.

To get 192-bit security with RSA you'd need 7680-bit RSA key and with ECC you need 384-bit key as mentioned in the article. That assumes classical attacks only. For quantum attacks, the smaller key sizes used with ECC do make it weaker.
