Is that confirmed or where you think they will sit.
best guess based on Vega FE which is the came core with more ram FE boost clock is 1600Mhz vs RX Liquid's 1677Mhz
liquid will likely be able to hold that but the air cards i dont think other then AIB cards wont get any where near the boost clocks under gaming loads for more then a few minuets
Vega 56 imo will be = to Fury X
