Power consumption during gaming
Now we come to the power consumption in games, where the TBP of 320 watts is put into perspective very quickly, depending on the resolution and feature set of course. In QHD, the new card is even more frugal on average than a Radeon RX 6800XT, which already indicates an enormously increased efficiency. It is and remains a tangible surprise.
Even in Ultra-HD without CPU limit, it is still clearly ahead of the Radeon RX 6800XT, which is again astonishing. However, I’ll come to the efficiency analysis across all cards and resolutions later. First of all, we are talking about the wattage figures, and they are more than just pleasing.
If you use the supersampling helpers, the image is fortunately preserved. And we can also state here that the new GeForce RTX 4080 together with the GeForce RTX 4090 is virtually the measure of all things when you put everything in relation to the achieved gaming performance.
Power consumption in factory state as summary
Yes, I did run Furmark at 355 watts with the Power Target set to maximum, but that’s basically pointless and purely for the gallery. But again, I briefly checked the load peaks and found nothing that would contradict all the other measurements and statements. However, the 18 watts at idle can only be achieved on AMD systems when the BIOS has been adjusted by the manufacturer so that the PCIe slot does not stop at @4 during idle, but also clocks down.
Load sharing between PCIe slot and external 12VHPWR connector
NVIDIA has connected all 13 phases to the 12VHPWR, which makes sense that way. The PCI-SIG says in the PCIe 5.0 specification that the card may consume a maximum of 600 watts of power in the sum of all 12 connections. Although this is slightly exceeded by a few watts in extreme cases, it is still quite accurate within the permissible tolerances. Instead of the maximum possible 5.5 A, it is only 1 A in the measurements, even in extreme cases.
