TS-100, the Su-33's fire-control computer, has a computing speed of only 170,000 times per second, while the J-15's fire-control computer has an estimated computing speed of over several million times per second.
The J-15 owns a much more advanced radar system than the Su-33. Due to its backward avionics system, the Su-33 can only serve as interceptors, and is incapable of air-to-ground precision strike.
The J-15 adopts improved materials and production techniques, and thus has greater strength and lighter weight.
Finally, the J-15 is powered by home-made Taihang (WS-10) turbofan engine, which is more powerful than the Su-33's engine. Overall, the J-15 is superior to the Su-33, and is comparable to world-class carrier-based aircraft such as the United States' F-18 and France's Rafale.
