  • The 4090 isn’t that much better than the 4080, and the 4080 is much more energy efficient

    The 4090 often beats the 4080 with a margin of 25% or more often has a one percent low figure better than the average frame rates delivered by the 4080. If that is not enough for it to be considered much better, I don’t know what is.

    Regarding your comments on efficiency, generally the high end is not as efficient as the other GPUs as they are pushed beyond the ideal point of the voltage-frequency curve to extract the most performance. And even after this, in GPU bound scenarios, the 4090 does great as it uses 25-35% more power to deliver 20-30% better fps which puts it on average around 10-15% behind in efficiency which is not enough in my opinion to claim that the 4080 is much more efficient.
