Two reliable sources, kopite7kimi and hongxing2020, have revealed that NVIDIA's upcoming GeForce RTX 5090 and RTX 5080 graphics cards will have thermal design power (TDP) ratings of 575 W and 360 W, respectively. Previous rumors suggested that these GPUs would have total graphics power (TGP) ratings of 600 W and 400 W, which encompass the power consumption of the entire GPU including its RAM and other components. However, TDP is a more specific value that pertains to the power consumption of the GPU die or the specific SKU.
According to the latest leaks, the GeForce RTX 5090's GB202-300-A1 GPU die will consume 575 Watts, with an additional 25 Watts allocated for GDDR7 memory and other components on the PCB. On the other hand, the RTX 5080's GB203-400-A1 chip is said to draw 360 Watts of power, with 40 Watts reserved for GDDR7 memory and other components.
The RTX 5080, despite being a lower-end model, consumes more power than the RTX 5090 due to its GDDR7 memory modules running at 30 Gbps, compared to the RTX 5090's 28 Gbps modules. While the RTX 5090 may use more or higher capacity modules, the first-generation GDDR7 memory requires additional power to achieve the 30 Gbps speed. Future iterations of GDDR7 memory may be able to achieve higher speeds without a significant increase in power consumption.
