, and 45% better performance than a 3090ti while using 2% less power (at 4k).
Can't find the link now, but I saw a youtube video where they did an analysis of it at different wattage limits and it performed very nicely.
4090 draws a lot of power, but Nvidia has just chosen to work at the diminishing returns end of the curve.
It's a halo product for people who will pay for the top of the range. I mean, look at the price!
