Thermal Design ╬ Videocard TDP Chart - Performance / Power
Let's compare graphics cards {GALAX GeForce GTX 1080} and {KFA2 GeForce RTX 3090 HOF Premium} in thermal efficiency. Temperature control (TDP) is an extremely important indicator. The higher it is, the harder it is to cool the graphics processor when performing complex computational workloads. The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power. Find answers to important questions: - What is TDP in video card? - What is TDP temperature? - How do I check my GPU TDP? Compare the performance of the two GPUs and choose the appropriate one.
