GPU performance questions.

Hello,
Witch specs distinguish one GPU performance from another the most? Looking at specs it looks that CUDA/Stream ,GFLOPS, memory bandwidth and fill rate is increasing on every stronger GPU. While core clock, memory clock doesn't change much or even is lower on higher end cards.
Looking only at core clock you can't say anything. Meanwhile it seems that looking at CUDA/Stream you could say witch GPU is faster. Would it be correct to assume that CUDA/Stream is main stat for a GPU?

Can it play a game at the fps you need and the settings you want. That is all that matters.

Nope, I wan't to know how it works.

How what works? You ask how to distinguish performance from one card to another, that's how. It's a game to game thing, not a universal.

Basically this, what makes a GM200 a GM200 and not GM206

As I imagine there should be a stat witch you increase others increases respectively

If you're talking about units it's not that easy. A 390x has more shading units than a 390 but barely out performs it. Clock and memory speed don't translate between different models let alone manufacturers. Price doesn't mean much and changes between regions. It really does come down to the task you have in mind to judge one GPU to another.
