The per-die price is something that has been on my mind in regard to pricing. I still see people complain about Nvidia's pricing on the 2000 series, but I think it's ignoring two factors: die size and process maturity. Basically, the 2000 series dies are significantly larger than their predecessors with the 2080 Ti (754mm²) compared to the 1080 Ti (471mm²) coming in at 60.1% bigger. The 2080 (545mm²) doesn't fare much better when compared to the 1080 (314mm²) with the difference being 73.6%, but the 2070 (445mm²) is a bit less worse compared to the 1070 (314mm²) with the difference being 41.8%.
Another important factor is whether these big dies are coming out working. Unfortunately, I can't find any yield numbers on TSMC's "12nm" process. Although, given that it's really just a modification of their 16nm process, which Pascal was already using, it shouldn't be that bad on yields.
All in all, you've got more expensive dies on what probably amounts to slightly worse yields. If Nvidia wants to keep up their bottom line, you're going to end up with a more expensive product. Now, what I think you can rightfully be annoyed at is that while Nvidia may be raising their price in line with BoM increases, the problem is that the BoM costs don't change the fact that ray tracing is pretty much useless right now.
