I'm sure there was a specific set of use cases that NVidia found where the increased memory speeds made a difference enough for them to warrant the design choice, the question is will most gamers encounter them. But alternatively starting with GDDR6X out the gate gives them the option, later on, to maybe release cards with slower non X at a cheaper price or with more memory at the same price should the need arise and if there is a minimal impact on actual gaming than yay?
Youre not going to see GDDR6X on the 3060 and 50ti cards. Those are the cash crop cards for nVidia. Especially looking at steam hardware survey as evidence.
As far as the general user, they see a 30% uplift in performance but they dont see the little old man behind the curtain. But Im calling voodoo magic like DLSS 2 to reach this level.
Im not shilling for AMD here but being fair. It would appear that AMD doesnt have DLSS like tech as of now and thier card demo teaser shows that the raw raster performance is faster than nVidja 3080 with all of its voodoo magic tricks enabled. This means AMD is so far a much more powerful card if looking at this objectively.
So I have to ask, with all the voodoo magic on or off at least for gaming does (X) mean anything other than a bragging bullet point?
