Comparing 4070 to 4090 is like comparing 1660 Ti to a 2080 Ti ~~ +180% more cores. +100% bandwidth and is 120% faster as average of those two components.
but there is a third one, 1660 had 48 rops. and this would be the equivalent of 4070 having 96, and it only has 64.

Now with 4090 being exactly 2x4070 faster in 4K, considering 4070 should be loosing 10% of efficiency at 4K this is a terrible result for the 4090.

4090 with 1008 GBs is the equivalent of 4070 with 336 MBs in the sense that it would be a disaster. Therefore 4090 should have 1512 GB/s and this is where GDDR7 comes into play.
And only then we can expect it to be 2.5x faster. loosing some efficiency but not as bad as a 1080 Ti and 2080 Ti that only had 38% more bandwidth and Rops than 70-class, so +55% perf. made sense.

It definitely would be interesting. My 4090 overclocks to 1152GB which is about 14% more bandwidth vs stock for a whopping 1-2% increase in performance. Hopefully GDDR7 brings better latency etc as well.
I've never had a flagship scale linearly with bandwidth there was always diminished returns the massive L2 cache is likely offsetting this a bit.

I for one am ok with 100% more performance in RT heavy games it's more than what we got last generation for about the same price increase. My guess is if the 4090 was 150% faster than the 4070 it would be a lot more expensive.

The 2080ti was 328% more expensive than the 1660ti the 4090 is only 166% more expensive than the 4070 so not a very good comparison really from a cost increase perspective. Also TPU database only shows the 2080ti as 92% faster than the 1660ti.
