The GeForce RTX 3090 is to be the absolute king of performance.
We recently informed you about new details regarding the specifications of the most powerful graphics cards from the Ampere family, according to which the GeForce RTX 3090 would be the equivalent of the Titan RTX. The German website Igor’sLab, which is considered a reliable source of leaks, revealed that the TGP (Total Graphics Power) factor of the top model is 350 W, and the core itself (GA102) consumes 230 W. It is, despite the use of a chip made in 7nm lithography, but Nvidia apparently does not want to compromise on performance. For comparison, the maximum power consumption in selected non-reference GeForce RTX 2080 Ti is “only” 260 W. In order to tame this beast, the “greens” must try to provide adequate cooling (this may be the new Nvidia card). The Igor’sLab portal tried to break down the RTX 3090 in terms of power consumption into prime factors, which you can read below.
GeForce RTX 3090 – approximate energy consumption and loss:
- TGP (whole graphics card power consumption): 350 W
- 24 GB GDDR6X memory (384-bit bus): 60 W (2.5 W per memory module)
- MOSFET, inductor, NVDD (GPU voltage): 26W
- MOSFET, Inductor, FBVDDQ (Frame Buffer Voltage): 6W
- MOSFET, inductor, PEXVDD (PCI Express voltage): 2W
- Other voltages and input section (AUX): 4 W
- Fans and others: 7 W.
- PCB losses: 15 W
- GPU core: about 230W
As can be seen from the above schedule, the difference in the TGP index compared to the most powerful Nvidia card from the previous generation is very large, What it should also translate into a significant increase in performance in the Ampere systems planned for this year (rumors say even 40-50%). You should also bear in mind that in this case we are talking about the GeForce RTX 3090 card in the Founders Edition. In the top non-reference models, the power consumption could be even higher.

The Igor’sLab portal also suggests that mass production of the GeForce RTX 3000 is scheduled to begin in August this year. The premiere of the first cards would then take place in September. According to unofficial reports, the GeForce RTX 3070 and 3080 would be on the market at this date. A little later, in the fourth quarter, the GeForce RTX 3080 Ti card would be released, while the weakest GeForce RTX 3060 would debut in the first quarter of 2021. It is not known when the premiere of the GeForce RTX 3090 would take place. It remains to be patient.
