NVIDIA recently announced the GeForce MX450 based on the TU117 GTX 1650 GPU but was quiet about the specs or performance. Chinese publication Zhuanlan has managed to take the MX450 for a test ride and found that it offers a very good performance bump over the MX350. However, this is at the expense of reduced memory bandwidth and raster operator (ROPs) count along with surprisingly higher power draws compared to the GTX 1650 Max-Q.
