Here’s a breakdown of each RTX 30 series GPU and their Thermal Power Specs: GPU
Fear not though, as the RTX 30 series is a little bit less demanding than that at least. Seasonic have previously confirmed that they recommend an 850W PSU for the RTX 30 series, which got a lot of people worried about needing to buy a brand new power supply for their system. But what power supply do you need for the RTX 3090, 3080, and 3070?
Rtx 3090 power consumption upgrade#
Nvidia’s next-gen RTX 30 series graphics cards are nearly upon us, launching in just over a week’s time (at least for the RTX 3080 that is) this has obviously gotten a lot of us excited to upgrade our PC hardware in time for the next-gen consoles and games. That said, I am still fairly certain that the NVIDIA premium will remain higher than Radeon counterparts - just not as high as the RTX Turing series. With the next-gen consoles rocking 10+ TFLOPs of power, NVIDIA will also be feeling a lot of pressure to not only offer higher performance but in a comparable price bracket. Since Computex is canceled, NVIDIA will likely be going with a virtual event again although we expect the timeline to be unaffected (still around September). The RTX 2000 series was relatively deadpanned compared to the reception of the GTX 1000 series and I think NVIDIA will likely want to capitalize on the opportunity of the new process by increasing their Total Available Market (TAM). I also have a very strong suspicion that you are going to see NVIDIA slash performance per dollar pricing across the board as well. We have already heard rumors that they have up-specced the RTX 3080 (and pretty much all their lineup) so users will be looking at double-digit performance gains (think 40-50%) going from the RTX 2000 series to the 3000. Shifting to the 7nm node will actually lower power consumption - all things held constant - but clearly NVIDIA wants to trade away the power efficiency gains from 7nm and instead roll out an absolute beast of a GPU. So what exactly is happening here? Well, what you are seeing is NVIDIA unleashing all of its fury in one single product. The custom boards are likely going to go even higher. All of this totals to a total board power of 350 watts for the RTX 3090 and keep in mind this is the FE. PCB losses are expected to be in the range of 15 watts and input section consumption will be around 4 watts.
The MOSFETs will consume a further 30 watts of power with the fan coming in at 7 watts. The RTX 3090's GA102 GPU core itself will draw roughly 230 watts of power with the memory drawing 60 watts. MOSFET, Inductor, Caps PEXVDD (PCIExpress Voltage) MOSFET, Inductor, Caps FBVDDQ (Framebuffer Voltage) MOSFET, Inductor, Caps NVDD (GPU Voltage) The complete breakdown of wattages (approximated to a few watts) is given below: Estimated Power Consumption / LossesĢ4 GB GDDR6X Memory (GA_0180_P075_120X140, 2.5 Watts per Module) Jensen is clearly missing his record quarters and it is showing. It would appear that NVIDIA is planning to go out guns blazing with a chip that is designed to run extremely fast and output a ton of heat. This also explains the heatsink we saw in leaks earlier because you would need an absolutely mammoth cooling solution to tame this beast. This is a massive increase in power consumption - one that will likely be accompanied by some truly phenomenal performance gains. The RTX 3090 (or whatever NVIDIA decides to call it) will have a TGP of 350W and a TDP (GPU only) of 230W. This is why this particular leak is very interesting.īefore we go any further, however, let's contextualize this leak: the RTX 2080 Ti had a maximum TGP of 260W on some custom variants. I don't know of any gamer that would rather have a power-efficient card instead of a powerful one in the same price. NVIDIA has usually played nice with power consumption on its graphics cards for the sake of power efficiency but gamers don't usually care for the same. NVIDIA's Flagship GPU RTX 3090 Gets TGP Breakdown, GPU Core TDP Itself Is 230W In other words, the TGP and its breakdown is not a rumor, although we are still not a 100% sure on the nomenclature (NVIDIA may decide to call it something other than an RTX 3090 or play around etc). The information comes from Igor, who has been an incredibly reliable source of leaks in the past and we have also independently confirmed the same. NVIDIA's next-generation RTX 3090 flagship GPU will have a significantly increased TGP of up to 350Ws.
