The NVIDIA RTX 5050 Mobile is the objective winner of this comparison, securing victories in six out of seven measured specifications. Its most significant technical advantage over the NVIDIA GTX 1660 Ti is its support for AV1 encoding, which represents a 100% improvement in this specific capability. While the older card maintains a lead in memory bus width, the newer mobile component dominates the majority of the evaluated hardware metrics.

Users who prioritize modern media processing and advanced encoding features should select the NVIDIA RTX 5050 Mobile for its superior AV1 support. Conversely, the NVIDIA GTX 1660 Ti remains the appropriate choice for those who specifically require a wider memory bus, as it offers a 50% advantage in that category. Your final decision should depend on whether your workflow relies more heavily on modern encoding standards or the specific memory architecture provided by the older hardware.
