It is almost time before we can present you our full review of the GeForce RTX series graphics cards. But first we'll be taking an architectural deep dive into the Turing graphics processors, and of course, we can share with you all specifications, you know the nitty gritty stuff.

I like the look of the Duke better than the Gaming Trio.

DLSS =
- Take angle under which 2 edges intersect
- take color information at edge
- load resulting pixel values from database

Variable rate shading =
- 1/2 precision
- 1/4 precision
- 1/8th precision
- and lovely 1/16th precision
This for sure boosts performance. Gamers will have mandatory camera tracking their eyes...

TSS =
- Bake in results into texture on the fly
- use old information to skip actual work
- update baked in texture from time to time (or at rate you feel comfortable with)
- probably would not be as bad as it seems if we had higher than 16xAF

To sum it up: New features can be paraphrased as "Way to cheap out IQ for performance gain."
Maybe good for 8K, somewhat OK for 4K. But hit to per pixel quality on 1440p will be unpleasant. On 1080p unacceptable.

Same here, Duke all the way. Regarding the architecture, it's clear where the gaps are that will be filled by the 2080+ and the Titan X (looks like there won't be a 2070 Ti). Anticipation for the reviews at like at 11.
