Quite honestly I did not expect a card with slightly faster graphics memory to make this much of a difference performance wise. On a relative scale, everything is just that, ... relative. As seen from the regular Gaming X model I doubt you're going to notice a few FPS more. But the fact remains that just that 10% faster memory is responsible for an extra 4% in gaming performance (compared to the standard Gaming X). And once we tweak that card that difference is roughly 10% faster compared to the regular Gaming X card. And when we take relativity one step further, once you compare all the way back to a reference (Founders Edition) GeForce GTX 1080 and apply a tweak, you can again up-to 20% in performance. And that certainly is interesting. Other then that, the card is 100% similar towards its younger sibling. And sure, you also need to factor in that every and any other 1080 can be manually tweaked as well. See, everything is relative ;-)

The new 11 Gbps memory is really good, and we reached a whopping 12.7 Gbps effective (!). And as this review proofs, Pascal GPUs do like their memory bandwidth so if you can find a high enough stable tweak, definitely go or it if you are seeking that last bit of extra performance.
