Did Wei give up too early?

Today, in Tata Steel tournament Wei resigned against Carlsen in the following position but it seems he could have tried a bit more. This is a very difficult position to win. I tried many times against SF level 8 but with no success.

4. Rexc3 is +5.6 in Stockfish 8. White simply puts his R on the seventh and and either eats the Qside pawns or pushes the d pawn if B defends them. Black is totally busted.

Yes, I I know; but try to play against the engine.

it is carlsen and not you he is much better, even better than the stockfish lvl 8
