Something does look wrong with Doom on Blackwell right now. I see the 4070 matching the 5070 and the 4080 beating the 5080 which should probably never happen.
If you look at 5080 vs 4080 Super in Indiana Jones, which is somewhat the same engine, the 5080 should be beating the 4080 super significantly. I would guess performance numbers for this game are going to change quite a bit at launch or shortly after.
It is interesting that Hardware Unboxed has 9070xt beating the 5080 and DSO gaming has the reverse. I'll be interested in seeing more benchmarks to get a real sense on what's going on.
