MSI GeForce GTX 1660 SUPER Gaming X Power Consumption
I compiled the power consumption results by testing each card under idle and full stress when the card was running games. Each graphics card manufacturer sets a default TDP for the card which can vary from vendor to vendor depending on the extra clocks or board features they plugin on their custom cards. The default TDP for the GTX 1660 SUPER is 125W (Reference) while the cards I tested feature custom PCBs with better power delivery. This puts the TDP of the card around the same level as the GeForce GTX 1060 and GeForce GTX 1660 which was also at 120W.
Also, it's worth noting that the 12nm FFN process from TSMC is a refinement of their 16nm FF node. NVIDIA is cramping even larger amounts of transistors and more cores than their previous cards, making it one of the densest chips built to date. It's likely to consume a lot of power and the results are reflective of that.
