Power consumption in factory state as summary
The idle power consumption is disproportionately high, varying between 16 watts and up to 45 watts. With a second monitor, this quickly becomes 70 watts and more (peaks over 90 watts). We can see the different interpretations of the power limit, with the MBA card being the most sensibly configured. Sapphire’s RX 7700XT Pulse is a tad slower, but still a bit hungrier in terms of power consumption in gaming. Sapphire uses its own board, which may well result in different efficiency numbers. Or it is simply chip lottery. The two RX 7700XT don’t have anything in common (fas), whereby the card with the higher power limit is clearly ahead in gaming. The rest actually speaks for itself and doesn’t even need to be verbally expanded on.
Load distribution between the PCIe slot and the PCIe sockets
The distribution of the power supply of all four cards shows that the cards have large reserves at the PEG, which is very pleasing. While the two 8-pin connectors are fully utilized, the motherboard slot is really very much in the running. In contrast to the RX 7900 XTX(X), this looks really good.
While NVIDIA has almost completely stopped supplying via the PEG for a long time, AMD also does not use this rail so excessively now.
