from the pic,the 054A-529 is not much smaller than Sovremenys, I suspect the real tonnage of 054A that official gave,because the Art of War told us:war strategy means sneaky.
That picture does not really reveal the differences in size of these vessels. The Length of the Proj 956 vessels is 156.5 meters while that of the Type 054A is 125 meters. That's 30 meters longer. The beam of the 956 is 17.5 meters, while that of the 054A is 15 meters. Two meters wider does not seem like much, unitl you take it the entire length of both vessels, that extra width the whole length of the 054A and then the extra width and length thpose last 30 meters.
Then there is the weapons fit. The 956 has a much heavier weapons fit than the 054A.
All of this adds up signifanctly and lead to the disparity in diplacement of 3500 tons which could very easily be realized with all that extra lengeth and width and the weapons fit.
A better picture is one that shows them from overhead, at dock, next to each other directly from the side.
