My EVGA GTX 1080 ti FTW3 Hybrid had problems recently. I contacted support and received a RMA. I assume that no replacement GTX 1080 ti FTW3 Hybrids were available because I received a RTX 2080 XC Hybrid in it place. What I've noticed so far, is that at both stock speeds and at its maximum stable memory and GPU overclock, the 2080 Hybrid is giving me lower scores in some 4K resolution graphics benchmarks and lower FPS in games at 4K resolution. Also, possibly due to the lower memory capacity and lower memory bandwidth, encoding video in adobe premiere pro CC/adobe media encoder with CUDA acceleration is taking longer compared to the same video projects when I had a properly functioning GTX 1080 ti FTW3 Hybrid.
I noticed the RTX 2080 gives equal or better performance in 1080p gaming and benchmarks, but doesn't consistently give equal or better performance in 4K gaming and 4K game benchmarks. For example, with my RTX 2080, the two FireStrike Extreme benchmark scores I've been able to obtain was 12,878 with a graphics score of 14,307 and 12,920 with a graphics score of 14,282. My GTX 1080 ti scored 13,701 with a graphics score of 15,500. My RTX 2080 is able to have a higher stable overclock on both the GPU and memory than my GTX 1080 ti was capable of. Yet the RTX 2080's benchmark scores at 4K are lower at both stock clock speed and overclocked. The the results of in the game benchmarks that I tried at 4K at lower with the RTX 2080. It doesn't appear that there is anything wrong with my RTX 2080, so is the GTX 1080 ti just that much better when overclocked?

EVGA GTX 1080 ti FTW3 Hybrid
I tried with three different drivers and couldn't get better results for the RTX 2080.
I also looked up the TFLOP performance of the cards. I know TFLOPS doesn't equal FPS and is just a rough estimate of the GPU performance in certain situations. This is the info I found from Nvidia for the founders edition/reference design cards:
GTX 1080 ti 11.3 TFLOPS
RTX 2080 Super 11.1 TFLOPS
RTX 2080 TFLOPS 10.1 TFLOPS
Based on that, the GTX 1080 ti looks "faster" than the RTX 2080.
What benchmarks or games does EVGA use to determine equal performance? Is it just that the games I have do worse with RTX cards at 4K resolution for some reason? Are the cards only compared at 1080p? Did I get some magical golden silicon lottery jackpot GTX 1080 ti GPU on my FTW3 Hybrid?
I had another question about the warranty. I purchased the extended warranty and the advanced RMA for my GTX 1080 ti. The warranty from the 1080 ti carried over to the RTX 2080, but the advanced RMA didn't. Why is that?
