The RTX50 series is about to be released, and the specifications are becoming clearer and clearer. Now we have learned the latest statement on the power consumption of the entire card of RTX5090 and RTX5080, which should not change again.The power consumption of the RTX5090 was originally said to be 600W, but is now set at 575W. This may be due to previous rumors or adjustments. Anyway, the good news is that it has been reduced. The bad news is that compared to the RTX4090, it has increased by a full 125W.
Even on flagship cards, such changes are very rare.
16-pin power supply interface
You must know that the power supply limit of a single 12V-2x616-pin interface is 600W, plus the 75W of the PCIe slot, the total is only 675W. I believe that the top non-public version of RTX5090 will easily approach this limit.
If this continues, in the next generation of flagships, a 16-pin interface may not be enough.
Taking into account the ultra-high power consumption of AI accelerators such as B100, B200, and B300, which often exceed kilowatts, it seems that the energy efficiency of the Blackwell architecture is really average.
The power consumption of RTX5080 is 360W, which is acceptable. It is much lower than the 400W rumored in the early stage. Compared with RTX4080, it has increased by 40W.
The next step has not been completely finalized, but it is said thatThe power consumption of RTX5070Ti is 300W, a comparison increase of 15W; the power consumption of RTX5070 is 250W, a comparison increase of 50W.
