I just upgrated my system and changed my GPU to RTX 2080 Ti. While I waited for the new card, I sold my old Titan-X card and I managed to get my hands on Radeon HD5870 card while I waited my new RTX.
I decided to benchmark HD5870 against RTX 2080 Ti just for fun. I am very sorry about the fact that I constanly mess up with the name of Radeon HD5870 as many times I refenece it by name HD5780. But still it was fun to benchmark both of these cards
Here is these benchmarks, can you see the difference?
