You have to include all of the price points or it doesn't make sense.

3090 $1100
3060ti $400

4090 $2200
4070ti $800

3060ti = 40% slower than 3090, 36% of the cost of a 3090
4070ti = 40% slower than 4090, 36% of the cost of a 4090

4070ti = As fast as a 3090, costs 37% less than a 3090

If you have $800 to spend on a graphics card, the 4070ti will be the best buy until AMD makes a counter move.

Did you just make up numbers for the 3090 and the 4090?

Pretty sure their MSRPs are $1499 and $1599 respectively.
