The NVIDIA RTX 5050 Mobile is the objective winner of this comparison, securing six out of seven total spec victories. While the NVIDIA GTX 1660 SUPER maintains a notable advantage in memory bus width, which is 50% better than its competitor, the RTX 5050 Mobile offers a more modern feature set. Its most impactful advantage is the inclusion of AV1 encoding, which represents a 100% improvement over the capabilities found in the GTX 1660 SUPER.

Users who prioritize advanced video processing and modern encoding standards should choose the NVIDIA RTX 5050 Mobile for its superior AV1 support. Conversely, the NVIDIA GTX 1660 SUPER remains the appropriate selection for those whose specific workflows rely on a wider memory bus. By weighing the importance of modern encoding against memory bus capacity, users can determine which component aligns best with their technical requirements based on these distinct hardware advantages.
