In terms of real time raytracing the RTX will blow the GTXs out of the water...

For anything else? Remains to be seen.

This is my big question too. It's pretty standard marketing: if your new product isn't impressively better than the old one on commonly used benchmarks, you invent a new benchmark where your new product is impressively better. I wonder how much of the "look how much better these cards are at ray-tracing!" actually reflects real-world improvements users will see, and how much is there to create a benchmark that shows a big improvement over existing GPUs.

I don't think it's that bad. The RTX is a whole new architecture and will have significantly more cores. The bigger question is probably just how the performance is compared to the price and power consumption.

Realtime raytracing wasn't feasible before.

For fp16, int8 and int4, the RTX blows the GTX out of the water. For fp32 it's a tiny increase. The memory bandwidth is about 40% higher as well. You'll always find people complaining about each release, but overall I think this is a solid card.
