AMD Adrenalin Control Center Settings
All AMD settings are set so as to be apples-to-apples when compared to NVIDIA’s control panel settings – all optimizations are off, Vsync is forced off, Texture filtering is set to High, and Tessellation uses application settings.
We use Wattman to set the RX 590’s power, temperature and fan settings to their maximums.
NVIDIA Control Panel settings
We used the latest beta of Precision X1 to set the GTX 1660’s highest Power and Temperature targets and for our overclocks. By setting the Power Limits and Temperature limits to maximum for each card, they do not throttle, but they can each reach and maintain their individual maximum clocks. This is particularly beneficial for high power cards.
Let’s check out the performance of our competing cards to conclude how they stand each manually overclocked in relation to each other.
