NVIDIA GeForce GTX 680 To RTX 2080 Ti Graphics/Compute Performance
GiMark saw a 42% increase in performance with the RTX 2080 Ti while the performance-per-Watt jumped up by 26%.
The Pixmark Piano test meanwhile was the most extreme example we've seen in these conventional graphics tests where the RTX 2080 Ti was repeatedly more than twice as fast as the GTX 1080 Ti and was still rendering correctly, etc.
Unigine Heaven at 1440p ran just below 30 FPS on the GeForce GTX 680 but with the RTX 2080 Ti is now 6.3x faster with a 166 average FPS.
The performance-per-Watt from Kepler to Turing with Unigine Heaven is a 3.9x improvement.
