The main differences will be the overclock that is applied from the factory, and that mostly depends on the quality of the cooler and fans, and the quality of the power delivery components. Lower end cards will have louder and less efficient coolers, and a less capable power delivery system which will make an overclocked card less stable and more prone to overheating. But in reality the difference is minimal, like low single digit performance difference minimal.
