It can aslo mean that the shaders aren't fully used. Some years ago, I don't remember if it was with Fury or the Vega cards, AMD had that problem. Those cards had something close to double the shaders of the regular, mainstream cards but didn't offer twice the performance because the chips wasn't well scaled and not all shaders could be used. Something akin could have happened this time to Nvidia, only to a less extend.

Another option would be that drivers still need to mature more and can't take full use of the new hardware.

Yeah, but think about it. If you say the shaders advertised are full shaders and believe Nvidia when they say their shaders can now do double the calculations, wouldn't that mean we have to expect quadruple the power when the shaders are doubled? Even with bad optimization we'd still see something like 3x the performance. Yet, despite having more than double the shaders and a noticeably higher clock we're not even at double the performance.

That can only mean that the Ampere shaders are not comparable to Turing shaders, yet they are both called "shaders". Wouldn't that be false advertisement?

Well, Nvidia's Tech Days will be later this week so we'll soon find out soon what's real and what's not.
