Nvidia MX450 review (can use google translate)
-
@AluminiumTech Quite the opposite. It says that despite sharing TU117 with GTX1650 and only slightly cut down core count, the heavy memory bottleneck (even with GDDR6) and hopeless ROPs bottleneck means even at its highest power draw config, MX450 is a significant downgrade over the 1650M. Compared to the 1650MQ, indeed performance gap is much smaller, but since the test sample is already showing the MX450's best (i.e. highest power draw version), you can still expect major differences when using retail devices carrying either GPU.
