The 7970 and 7870 definitely had a worse price to performance vs their outgoing last gen.

The 7870 was horrifically bad offender. AMD was charging $350 for a 213mm2 die on a cheap node(vs the 231mm2 Polaris which ranged from $200/240 on a much more expensive node).
Looking at the above chart, the 6870 had 67% better price to performance than the 7870. The 7970 was pretty bad as well having the same price to performance as the gtx 580 which was Nvidia's worst card as far as price to performance while having a 520mm2 die size.
The 7970 was 351mm2 die and AMD was charging $550s for it, vs the 6970's $369(389mm2) or the 5870 $399 price(331mm2). This comparison is actually favorable to AMD because this is using initial street pricing of those products. Not the EOL or clearance pricing.
AMD's initial pricing for the 7970/7870 was the trigger of the massive price inflation of smalls chips. AMD which is usually the value company which keeps pricing in check, decided to capitalize on a 3 month window before nvidia released their cards. AMD took the savings which comes from the shrinkage of dies with a new nodal process and put everything in their pocket and charged a big premium for their new products.
Nvidia followed suit after their chips beat AMDs, thus pricing their chips relatives to their competition and we have the story we have today.
I agree the HD7970 and HD7950 had worse perf/$ than HD6970/50, BUT HD7970 was the fastest card at release and it had the same or a little better perf/$ vs GTX580 which had the performance crown at the time.
Today the RTX2080Ti is the fastest card but it has way worse perf/$ than the fastest card it replaces, the GTX1080Ti.
Even if you put RTX2080 against the GTX1080Ti the perf/$ is worse again. According to the NVIDIA slides, the RTX2080 is 13% faster but it cost 24% more than the GTX1080Ti. (prices today from newwegg)
HD7870/50 were the worst AMD perf/$ cards at the time of release, although they had the same performance as the HD6970/50 so perf/$ at the same performance level was the same with way lower power consumption. BUT again, HD7870 was faster than GTX570 at almost the same price giving the same perf/% against the competition.
