The power consumption of the RTX 3090 Ti has reached as high as 450W, and the non-public versions are approaching or even exceeding 500W. For this reason, a new PCIe 5.0 16-pin auxiliary power supply interface was launched, with a theoretical power supply capacity of up to 600W.
There have long been signs that the power consumption of the next-generation RTX 40 series graphics cards will be more exaggerated, even with the new TSMC 4nm process and Ada Lovelace architecture.
The latest information given by @kopite7kimi, a hardware exposure expert, shows that the design value of the RTX 4090’s entire card power consumption is still 600W, but it will use the residual AD102 core by convention.
The full-blooded AD102 core is expected to correspond to RTX 4090 Ti (or Titan), 18432 CUDA cores, higher frequency, and 48GB 24GHz GDDR6X memory. NVIDIA is testing, and the power consumption of the whole card reaches an astonishing 900W.
This is exactly the same as the RTX 3090 Ti, but the power consumption is doubled!
to this end,The RTX 4090 Ti will use two 16-pin power supply interfaces, with a theoretical power supply capacity of 1200Wwhich is exactly the same as the GALAXY Hall of Fame and EVGA KINGPIN RTX 3090 Ti.
However, such a card is just a test argument, and whether it will actually be released has not yet been determined.
@kopite7kimi also revealed that,RTX 4080 will be AD103 core, 16GB GDDR6X video memory, the whole card power consumption is expected to be 350Wroughly the same level as the current GA102 (in fact, it is a leapfrog).
RTX 4070 is AD104 core, 12GB GDDR6 core, and the power consumption of the whole card is also 300W.
By the way, the RTX 40 series will come standard with a 16-pin power supply interface, at least the public version, but it is said that none of them support PCIe 5.0.
