Then as per TPU adjusted:
4080 is 49% faster, 71% more expensive.
4090 is 96% faster, 129% more expensive. (perf adjusted as per you)
71/49 is 1.45
129/96 is 1.34
Difference is 7,59%.
The lower the ratio the better and should be seen as a better price/performance gain vs 3080.
Now take into consideration that you'll need the latest CPU to take advantage of that, maybe add the cost for 4090 of a newer PSU, possibly A/C unit

)
Anyway, under 8% difference is nothing. Ergo, if 4080 is awful, so is 4090.
LE: my numbers look at the general picture. For 3080 owners I guess isn't that great.
