Frame Generation seems to be enabled, and 19 fps seems like a notoriously poor result, especially with frame generation enabled. This would be a supreme edge case, mostly because it exposes the absolute worst case scenario for a RX 6800 XT - which was horrible at ray tracing to begin with. Personally, I expect somewhere around 80% faster than 6800 XT in "real world" RT workloads, less in pure raster, which should slot it in the RTX 4070 Ti Super's performance level or thereabouts. Guess we'll see in a couple of hours, although I'm probably going to be asleep when W1zz publishes the reviews.
Given the leaked results, it does seem like the extra 100 to 120 watts over the 5070 non-Ti is relatively consistent, although it should also be faster. I did notice something though, the 5070 uses a good chunk more power than the 4070 did. GDDR7 is supposed to be more efficient, so I'll chalk that to more aggressive clock speeds and more shaders, I suppose.
