GeForce RTX 3090 Rules But For the Price of Massive Power Consumption
The launch of Nvidia Ampere GPU is approaching. This is suggested by rumors, which have recently been multiplying on the web. From the latest leak, we learned more about GeForce RTX 3090 with 24GB VRAM, which is to replace Titan RTX and is characterized by huge power consumption.
We recently look like). Igor'sLab has tried to disassemble the RTX 3090 in of power consumption of individual components, which you can read below.
GeForce RTX 3090 - Indicative power consumption and losses:
- TGP (total power consumption): 350 W
- 24 GB GDDR6X memory (384-bit bus): 60 W (2.5 W per module)
- MOSFET, inductor, caps NVDD (GPU voltage): 26 W
- MOSFET, inductor, caps FBVDDQ (framebuffer voltage): 6 W
- MOSFET, inductor, caps PEXVDD (PCI-Express voltage): 2 W
- Other voltages, input section (AUX): 4 W
- Fans and other components: 7 W
- PCB losses: 15 W
- GPU power: approx. 230 W
As can be seen from the above analysis, the difference in TGP compared to Nvidia's strongest card of the previous generation is very big, which should also translate into a clear increase in performance in Ampere chipsets (rumors say of as much as 40-50%), which are planned for this year. It should also be kept in mind that in this case we are talking about GeForce RTX 3090 in Founders Edition. In the top non-reference models, power consumption could be even higher.
Igor'sLab also suggests that mass production of GeForce RTX 3000 is to start in August, this year. The launch of the first cards would take place in September. At this date, according to unofficial reports, GeForce RTX 3070 and 3080 would appear on the market. A little later, in the fourth quarter, the GeForce RTX 3080 Ti card would come out, while in the first quarter of 2021 the weakest GeForce RTX 3060 would make its debut. It is not known when the premiere of GeForce RTX 3090 would take place. It remains to arm oneself with patience.
