Looks as if you are comparing to the Platinum Card without Contactless. The card construction is different when the Contactless feature is present. (As far as I know there is no option to order the new Gold card without Contactless.)
I just pointed out it's thinner cause we were all wondering if it's the same thickness as plat. But it's still a good looking card. I'd love to see how it compares to the new gold metal card.
