The power consumption of those cards are certainly interesting.
Let's compare the 2080Ti with the rumored specs of the 3080, a valid comparison given that both have the same 4352 cuda cores. The 2080Ti is build on the less efficient 12nm compared to the 7 or 8nm of the 3080. It has 1GB more of memory on a wider bus (352 vs 320) and yet it's rated for 250W compared to the 320W of the 3080.
Where does the extra 70W of the 3080 come from? Because let's be honest, 70W is a lot, like the difference between the 2080Ti and the 2060 Super, and the faster GDDR6X memory can only be responsible of a part of that. So, again, why the extra power?
The only reason that comes to mind is that Ampere has a lot more Tensor and Ray Tracing cores than Turing, and that's why it uses so much power.
