We all know 7900 XTX is around the level of 4070 performance when it comes to rendering. I just find strange that it can deviate from this average so massively in Lone Monk scene. It’s just completely “off the charts” here for some reason.
Can anyone explain why, on the technical level? Or we can leave this to some technological anomaly/specific scene “optimisation” that just works well for RDNA3 here? It’s a demanding scene, so if anything, I’d expect the usuall bad result for XTX to get even more dramatic here.
There can be a lot of factors at play, from the specific Blender version used, along with the fact that it is just a single scene, which may well be only using Cycle features that the 7900 XTX happens to handle fairly well, while for another scene, it may not do anywhere near as good compared to say a 4090.
Add to that, the above spreadsheet list is maybe just a single run sample from a single card/PC.
For example, it lists the 3080 Ti at 185 seconds. Well, I have a 3080 Ti and just download the Lone Monk scene and hit F12.
My 3080 Ti rendered it in 163 seconds, also using Blender 4.3.2
Add to that I don’t really think it’s an all that demanding scene, it’s just that the sample count is set high at 4096. That is likely way higher then it needs to be, especially for a still render.
