I hope for 890M, that 15% at least is really needed. Not that 880M was bad for IGPU in handhelds, but I think it is kinda not there yet entirely for games say 2016-18 in decent graphics...

I don't understand how can you compare IGPs with what they gave Sony for PS5pro, that's a pretty powerful dedicated graphics, so the same power in IGP when, like in 10-15 years?

IMHO: Whatever iGPU AMD ends up including in the Z2 (extreme or otherwise) had better be MORE powerful performance wise then what they are currently offering in their OTHER desktop/laptop chips (IE: as good or better than what they gave Sony for the PS5-Pro) otherwise Intel may have them beat in the handheld market.
