Lately I learnt a lot about gpus, and it made me wonder what is the most important statistic on a video card? Is it memory clock? (probably not) amount of cuda cores? Core frequency? Amount of vram?
It made me think about because I was (and still am) planning on a gpu upgrade and ones most appealing were the 970 and the 390. The 390 is a superior card according to a number of sources I checked, and although future proofing isn't technically a thing, it has more vram, so it should run games 4 years from now better than a 970 would. But I'm really getting sidetracked although the 390 has more vram it's core frequency is lower than that of a 970, but still gets better performance in games, and I have no idea why.
So, what is the most important spec?
