Performance comes in around where I expected it to be. Perhaps a touch slower when the non-overclocked versions are tested, but not terrible really.
One of the things I have noticed is the reference to previous generation uplift and I really wonder if the comparison of 10xx series to 9xx series cards has skewed a lot of the expectation with the 20xx series over the 10xx series. When you look back at the 9xx series cards no one talks about the difference in VRAM at the time. A GTX 970 and 980 only had 4 GB of VRAM, (or some wags might say 3.5 GB for the 970) the 980 Ti only had 6 GB of VRAM. So when the 1070 and 1080 came out with 8 GB of VRAM, on top of the performance uplift of the Pascal architecture, and on top of the increase in GPU Core clock, all of this combined to produce a huge increase in performance uplift. As you look at today's release, the 2070 has 8 GB of VRAM, although it is faster VRAM, the same as the 1070 and 1080. It has a performance uplift of architecture, but the GPU core clocks are similar. This means it is more difficult to provide huge performance uplift, but it is still impressive that the uplift is still there. At least it is to me.
Anyway, thanks for the work on getting the review out. Funny how the 2070 release closely mirrors the Vega release, but the overall vibe I get from reviewers is much less forgiving of NVidia than they were of AMD, all things looking equal.
