Like, what mainly determines performance? Clock speed, memory clock, memory type?
For example, would a gpu perform better than a similar one if it had a slightly higher memory clock and a slightly lower core clock, or vice versa?
Thanks!

What determines performance? Primarily GPU architecture and size, not clock speeds. I have a little volt-modded GT430 clocked to almost 1GHz and a HD 6970 clocked at 880MHz that will completely murder the GT430. The best thing to look at is benchmarks. Game benchmarks and other benchmarks like 3DMark 11 or FutureMark or Unigine Heaven. The only time comparing clock speeds is relevant is within the same model of the same generation card. ie. a GTX 960 vs a GTX 960.
The one thing that is somewhat universal is VRAM, but in this current day most cards have plenty of VRAM for modern games. So it's not as big of a factor.

I'm not comparing two different graphics cards, I'm comparing two different models of one card, one has higher clock (rougly 25 mhz higher) but slower memory (800mhz slower). The other is the opposite.

I'd generally go for the one with a higher clock speed, overclocking the core clock always seems to have more of an effect than memory. But yes, what card are you referring to?

I'm looking at two models of the GTX 1080, the Amp Extreme and the Asus Strix OC.
