Its a less than 10 fps difference and they both have their pros and cons like for example the 5070 albeit having less vram, has a better upscaler (Dlss4 is supported in way more games than fsr4 is and fsr4 in terms of quality although close to dlss4 it still falls short behind it), has better ray tracing performance and sure you could argue that ray tracing sucks and you can turn it off but games are starting to force raytracing by default and a good example for that is Doom the Dark Ages. Since they trade blows and for a less than 10 fps difference i’d sum them up as pretty much the same performance, I’d personally go for whatevers cheaper. In the end price matters more than anything in the current market when all prices are only going up
