Its not about them jacking up the prices.
30 and 40 series GPU share similar price points
$1500-$1600 3090/4090 4090 charted better
$1200 3080 Ti/4080 4080 charted better
$500-$600 3070/4070 4070 charted better
$400/$400 3060 Ti/4060 Ti I didn't check the data at this point but they are probably close (if launch aligned)
$300/$330 4060/3060 I didn't check the data at this point but they are probably close (if launch aligned)'
If you simply look month by month the 30-series should be higher, since they launched more GPUs earlier. The fact that 40-series charted higher already is a good sign for the 40-series.
