If that's the spec these cards will barely outperform a 1080 Ti. Nope. I'll wait for what comes next unless it's at least a 30% performance improvement across the board. Updated process so about maybe 10% improvement per clock, GDDR6 so maybe another 5% or a bit more. Ray tracing is their big selling point here. Not worth the money for 1080 Ti owners. Add HBM2, then maybe it would get closer to the 20+% improvement over last gen.
...actually GDDR6 is faster in tests, less expensive, and easier to produce than HBM 2. For now, I'm content with the Titan-X I recently picked up. Yeah, a generation older than Pascal, but a big step up from what I used to have, perfect for rendering the large scenes I create and I can't complain about the price I paid.
Valid sources with actual real-world results please?
Another advantage is cost.
