Thus my comment on mixed architectures. To be fair on AMD its only the 5600U/5700U where there is a small amount of confusion. At least they are no longer mixing entire product lines as they did before with APUs being previous gen to the CPUs.
To this day, I STILL don't know the difference between Vega 6, Vega 8, or any other iGPU AMD has used in the last decade...
