It seems me in terms of market positioning it's more like a halo card, like a Titan. In terms of power/heat, it's more comparable to a dual GPU card of yore like the R9 295X2.
Do you mind elaborating on what you mean exactly by "a halo card", ie a Titan? What's a "halo" card exactly?...
So you think that the 3090 will either be a dual card or like the new Titan? Hence there will be a 3080 Ti or no? Or just a 3070, 3080 and 3090 (Titan)?...
This is obviously all just speculations and brainstorming, doesn't make it nonetheless interesting though
